Showing The First Tab On PanelTabbed Component In WebCenter Portal ( Spaces )

This issue of showing First tab on panelTabbed component in webcenter portal ( Spaces ) has troubled me for long.

Page A has three tabs. When user select second or third tab and then navigate to another page. When user comes back to Page A, his last selected tab is displayed instead of first tab.

Google Search for showing first tab on panelTabbed component gives you lot many results...and mostly works for adf application. Found a very little for webcenter portal framework ...but none for webcenter portal ( spaces ),

I knew that it has something to do with MDS ...disclosed tab getting persisted. Also verified that using RedSamurai MDS Cleaner taskflow. There were MDS file getting created persisting disclosed tab information.

Found the solution ...

http://dba-adf.blogspot.com/2014/02/showing-first-tab-always-when-enabling.html



 public void tabDisclosureListener(DisclosureEvent disclosureEvent) {     
        RichShowDetailItem tab = (RichShowDetailItem)disclosureEvent.getComponent();
        FacesContext fc = FacesContext.getCurrentInstance();
        ChangeManager cm = RequestContext.getCurrentInstance().getChangeManager();
        ComponentChange cc = new AttributeComponentChange("disclosed", Boolean.FALSE);
        cm.addComponentChange(fc, tab, cc);
        ........
    }

This will reset the disclosed property when ever any of the tabs where clicked.

ADF Skinning - Styling table column And Hiding checkbox in SelectManyChoice

Few ADF Skinning Tips

Recently I came across a OTN question and some requirements on ADF Skinning. 

OTN question : How to allow user to select multiple values in selectManyChoice but not showing   checkbox ?

Well first I checked whether it is possible to select multiple values using CTRL+CLICK without selecting checkbox ...and yes it is. So only thing left is to hide the checkbox. Well then all we need is correct adf skin selectors and some basic css. Here is the sample code :

Apply the smcCheckboxHide class on SelectManyChoice component 

          <af:selectManyChoice label="TestCheckbox" styleClass="smcCheckboxHide">

          <f:selectItem itemValue="MALE" itemLabel="MALE" id="si11"/>

            <f:selectItem itemValue="FEMALE" itemLabel="FEMALE" id="s1i2"/>

          </af:selectManyChoice>

and hide the checkbox in css using below code : 

af|selectManyChoice::content-input.smcCheckboxHide {

display:none

}

Refer to http://jdevadf.oracle.com/adf-richclient-demo/docs/skin-selectors.html

af|selectManyChoice::content-input - >Style on the native checkbox of the af:selectManyChoice component.

Another requirement that came up is to have right border on few columns in adf table. Again we need to lookup for the right adf skin selectors. Sample code : 

Apply the style class on column { rightColHeaderBorder for header and for datacell }

<af:column sortable="false" headerText="Name" align="start" id="c2" headerClass="rightColHeaderBorder" styleClass="rightColBorder">

            <af:outputText value="#{row.name}" id="ot2"/>

 </af:column>

Skinning code :

af|table af|column::column-header-cell.rightColHeaderBorder, 

af|table af|column::banded-data-cell.rightColBorder, 

af|table af|column::data-cell.rightColBorder{

    border-right-color: Blue;

    border-right-width: thin;

}

System Folder Delete And Recover Artifacts ( DataSource , Repository URLS)

This post talks about how to take backup of configured datasources and repository (SVN) connection.

Follow these steps :

STEP 1 :

Take a back up of below files before you delete the old system folder

• SYSTEM_FOLDER\DefaultDomain\config\config.xml
• SYSTEM_FOLDER\DefaultDomain\config\jdbc

Folder

• SYSTEM_FOLDER\o.jdeveloper.subversion\repositories.xml

STEP 2 :

Now delete the systemFolder

STEP 3:

Restore configurations

Copy the jdbc-system-resource elements into config.xml from the backup config.xml
Copy the contents of jdbc from the back up into the new jdbc folder
Create a dummy repository connection and Copy the svn-repository elements from the back up repositories.xml

Note that these steps only restore the SVN repositories and data sources.

Unfortunately all the encrypted passwords got corrupted.

So had to clear the password save and reset the passwords.

Hierarchical Dropdown in ADF

This post talks about how to display hierarchical dropdown in selectOneChoice.

There is one method explained by Frank here. Well this method show two levels in hierarchical dropdown using two af:ForEach iteration.

What if we have multiple level, and don't know how many af:forEach would be required. Other approach is to achieve required spaces through query to show dropdown structure. Thanks to my friend Prahlad for sharing this.

In below query, emp_disp will have appropriate spaces based on the level of the employee in the employee hierarchy.

select LEVEL,FIRST_NAME,LAST_NAME,
LPAD(FIRST_NAME ||' '|| LAST_NAME,length(FIRST_NAME ||' '|| LAST_NAME)+(LEVEL-1)*4,unistr('\00A0\00A0\00A0\00A0')) emp_disp
from EMPLOYEES
start with MANAGER_ID is null
connect by prior EMPLOYEE_ID = MANAGER_ID;

All you need to do is create a VO with above sample query and use this for dropdown.

Sample is uploaded here..

Handling Ok Cancel action on Uncommited warning popup

Handling Ok Cancel action on Uncommited warning popup

There are couple of post which covers how to show uncommitted data warning popup. So I will not go in details for that, rather we will cover how to handle ok cancel action on uncommited data warning popup.

Few references for, how to show  uncommitted data warning popup : 

http://www.oracle.com/technetwork/testcontent/unsaveddatawarning-096556.html

http://www.awasthiashish.com/2012/10/uncommitedunsaved-data-warnig-on-page.html

Select af:document from page structure and go to property inspector, now set UncommitedDataWarning to on.

Before starting with implementation, I would like to refer the information found on OTN forum : 
https://community.oracle.com/message/10982006#10982006

From looking at the design specs, uncommitted data warning is a combination of ADF view and ADFc functionality. Good news is that - at least by the specs - a dirty transaction in a region should be automatically detected. The class that handles the uncommitted data warning is AdfcDirtyPageHandler. This class is registered in a text file "oracle.adf.view.rich.context.DirtyPageHandler". So if this works as with how you change the ADFc exception handler, then its by a file with this name in the application META-INF/service folder (the latter doesn't exist by default). Note that "AdfcDirtyPageHandler" is in an internal package, which means its not supported to extend it. However, the default abstract class is DirtyPageHandler and this is in a public package. 
From the Java docs:
META_INF/services-based application-scoped object for tracking whether navigation will result in data loss.  Only a single implementation may be registered per application. Registering multiple implementations will result in an IllegalStateException at applciation initialization. If no implementation is registered, a default implementation will be used. That implementation will always return false from isDataDirty and will do nothing in response to a trackNavigation call.
Maybe worth filing an ER to get a public listener / hook into this instead of dealing with your own implementation. Will file one

To handle ok cancel action on uncommitted data warning popup : 

1. Create a text file with name "oracle.adf.view.rich.context.DirtyPageHandler" under folder structure :

    TestApp/.adf/META-INF/services/

2. Create a java class CustomDirtyPageHandler which extends "AdfcDirtyPageHandler".

public class CustomDirtyPageHandler extends AdfcDirtyPageHandler 

3. Update the file "oracle.adf.view.rich.context.DirtyPageHandler" created in step1 with the name of custom handler ( full package path ).

4. Now you are good to write your logic in CustomDirtyPageHandler java class.  In sample code below, Rollback is executed on OK action. Make sure that Rollback binding is available in pageDef of jspx.

Ignore the below warning/error :

Scroll to top on Commit or Rollback

Scroll to top on Commit or Rollback

This post is about scrolling to some component on user action. Mostly when user click save or cancel, a message is displayed on top of the page. At the same time, it is required to scroll the page to top and show message to the user... rather user scrolling up to see what happened. 

Implementation is simple : 

1. Need a javascript method to scroll.

2. Next step is just to invoke this javascript method at the end of your commit call.

Invoke Bindings from PageTemplate PageDef

Invoke Bindings from PageTemplate PageDef

There are scenarios when certain method binding in pageTemplate's pageDef needs to be invoked from some button Action in page. Here are the details :

2.  Now in order to access bindings in pageTemplate's pageDef, refer below code. Enjoy!!!

Show exceptions caught in Managed Beans

There are couple of scenarios when some exception is caught while executing some logic in managed bean. The post is about how to show those exceptions to user and when it is required to do it explicitly.

For most of the scenarios, ADFm Error Handlers shows the message. But in case when some exception occurs in managedBean, it can be caught and reported to ADFm Error Handler using below code.

BindingContext bctx = BindingContext.getCurrent();
   ((DCBindingContainer)bctx.getCurrentBindingsEntry()).reportException(ex);

Note : Using the ADF model error handling for displaying exceptions thrown in managed beans require the current ADF Faces page to have an associated PageDef file (which is the case if the page or view contains ADF bound components).

Sample App is uploaded here. Following scenarios are covered  :

	Scenario Description	Button Text in Sample App	Requires Explicit Handling to show messaage to User
1	Drag and Drop AM Method on Page as command Button	throwJboExceptionFromAM	No
2	Call AM method in Bean method through bindings	Call throwJboExceptionFromAM in Bean through Bindings	No. By default, all exception are handled by ADFm Error Handler when calling AMMethod through bindings. When you check for exception in operationBinding and report it expliclity .. It is basically duplicating the message
3	throw an exception in ActionListener	ThrowingExceptionInActionListener	Yes. See the button in section Handled and it's actionListener. How the exception is reported .

WebProxy - Log Request and Response xml to console

How to view the request and response xml for a webservice call made using webProxy.

To see the soap request and response we can set a JAX-WS parameter. 
"-Dcom.sun.xml.ws.transport.http.client.HttpTransportPipe.dump=true"  ,this will dump the data in your console output.

Edit the Run/Debug Profile for the project and then run it . See the screenshot for more details : 

You can also write a SOAP logging handler ....will be covered in future posts.

Groovy : Posted Attribute Value using groovy

How to get the posted attributeValue using Groovy .

 To expose old value of entity objects, follow steps below :

1.  Create transient attribute "OLD_SALARY" in Entity Object.

2. Make sure that "Persistent" and "Derived From SQL Expression" properties are turned off.

3. Set the "Value Type" to Expression and enter the following Groovy expression into the Value field:

adf.object.getPostedAttribute(adf.object.getAttributeIndexOf(model.EmployeesImpl.SALARY))

That's it... Now  old salary attribute holds the value of salary retrieved from database. If required same attribute can be used in viewObject ...

Uploading Large Files to UCM - af:inputFile Component

This post covers uploading large files to UCM using inputFile Component.

JDeveloper Version : Studio Edition Version 11.1.1.7.0

Recently I was working with af:inputFile Component trying to upload files to UCM. I hit an issue when trying to upload files larger than 2MB. I am going to share my findings :

1. InputFile component gets stuck if trying to upload large file... and it doesn't even allow to select other small file once it is stuck. I searched google and found this :

Andrejusb Blog - Oracle UCM 11g uploading large files


Set this parameter "org.apache.myfaces.trinidad.UPLOAD_MAX_DISK_SPACE" = 20971520 in  web.xml for upload up to 20 MB.{ maximum file upload size to 20971520 bytes, or divided by 1024 and one more time by 1024 - 20 MB }

2. Now again question is - what happens after that 20MB file ... inputFile Component gets stuck. Further digging found that it is component bug and patch is available.
