Q: I have an entity object-based view object and I use vo.clearCache.However I am getting oracle.jbo.TooManyObjectsException?How to solve this?
Answer:
When you clear the view object cache with vo.clearCache(), it does NOT clear the entity cache nor change the states of entities. Thus, if you try to insert the row with a key value that already exists in the entity cache; you get TooManyObjectsException.The solution is to remove on all
the rows in the view object.

Q: How do I determine the transaction state -- that is, whether changes have been made to view objects or not?
Answer:
We can use
-->ApplicationModule.getTransaction().isDirty() - This method tells you whether the transaction contains any changes in the view objects. This works for transactions made by entity object-based view objects only.
-->OAViewObject.isDirty() - This method tells you whether a particular view object contains changes or not. This works for both entity object-based view objects and view objects
based on OAPlsqlViewObjectImpl
-->OAViewObject.isDirty() - This method tells you whether a particular view object contains changes or not. This works for both entity object-based view objects and view objects

Q: When I am executing the VO query and after that fetching the attribute value from the VO, getting the NullPointerExecption?How to handle it?
Answer:-When you execute the VO.executeQuery() method, and if your query is fetching the record, then row pointer is at position -1. Either call the vo.first() method or call vo.setCurrentRowRangeIndex(0);

Q: Is there a way to determine if someone has used the personalize links on a Self-Service Web Applications page?

And to list of the PG files in particular top, execute the

Q: Is there a way to determine if someone has used the personalize links on a Self-Service Web Applications page?
Answer:
Here are several ways to identify if there are Personalization’s made to a page and what those
Personalization’s are:
1. The first and easiest way is to go to the page you want to check for Personalization’s, then click on the 'About this page' link at the bottom left of the page. Click on the Personalization tab. Then you should see a list of 'Effective Personalization’s', what elements have been customized and when they were customized/personalized.
2. Another way is to use the Functional Administrator. The first thing to do to use the Functional Administrator is to identify the Document Path. For example, go to the Notifications link from the Workflow User Web Applications responsibility, and then click on the Personalize Page link. Notice that the Document path for the Notifications page is: /oracle/apps/fnd/wf/worklist/webui/NotificationsPG. From the Functional Administrator responsibility Home page, click on the Personalization tab in the upper left hand corner. Insert the document path for the document you want to check - for example: Document Path = /oracle/apps/fnd/wf/worklist/webui/NotificationsPG and then click on the 'Go' button to get a list of Personalization’s for this page.
3. A third way to check to see if there are personalization’s on a page is to use sqlplus and run the
JDR_UTILS program. You will need the Document path to the page in question - again using the Document path for the Notifications page: /oracle/apps/fnd/wf/worklist/webui/NotificationsPG
Run the listDocuments function to drill down and find all documents that have been personalization’s under a certain Meta Data region:

Run from sqlplus:
set serveroutput on
exec
JDR_UTILS.listDocuments('/oracle/apps/fnd/wf/worklist/webui
/');
/oracle/apps/fnd/wf/worklist/webui/customizations/
Note, you do not include the Page ID (NotificationsPG) with this query. In my test case, notice that there are 'customizations' in this MDS region webui. The 'customizations' indicates that personalization’s have been made to the 'webui' region. Run the query again with the new path and notice that there are 'site' level customizations, although there could be other levels such as user, responsibility, ...:
exec
JDR_UTILS.listDocuments('/oracle/apps/fnd/wf/worklist/webui
/customizations/');
/oracle/apps/fnd/wf/worklist/webui/customizations/site/
Run the query again with the new path and notice that the customizations are at site level '0':
exec
JDR_UTILS.listDocuments('/oracle/apps/fnd/wf/worklist/webui
/customizations/site/');
/oracle/apps/fnd/wf/worklist/webui/customizations/site/0/
Run the query one more time with the new path and notice that the customizations are made to the 'NotificationsPG':
exec
JDR_UTILS.listDocuments('/oracle/apps/fnd/wf/worklist/webui
/customizations/site/0/');
/oracle/apps/fnd/wf/worklist/webui/customizations/site/0/No

Once we have identified a particular page or pages that have customizations/personalization, then we can use the printDocument to see what personalization’s have been made
to the page:

JDR_UTILS.printDocument('/oracle/apps/fnd/wf/worklist/webui
/customizations/site/0/NotificationsPG');
-------------
xml:lang="en-US"
customizes="/oracle/apps/fnd/wf/worklist/webui/NotificationsPG">
-------------
As you can see, rendered has been set to "false" for "MainRegion.NtfView". You can then use the deletedocument function to remove this personalization exec jdr_utils.deletedocument('/oracle/apps/fnd/wf/worklist/webui/customizations/site/0/NotificationsPG');
set serveroutput on
exec
JDR_UTILS.listDocuments('/oracle/apps/fnd/wf/worklist/webui

Q: How to remove a bad personalization from an OA Framework page?
Answer:
) Login to Oracle Applications with the system administrator responsibility
2) Update the Profile Option: "Disable Self-Service Personal" = YES
- This disables the rendering of all personalization that have been created.
- You can set this at the site or user level.
3) Navigate to the page you personalized.
4) Enter the personalization UI in the same way you did to create the personalization initially
5) Click the Delete button at the bottom of the page.
- This will remove the personalization from the page.
6) Go back to Oracle Apps with the system administrator responsibility
7) Re-enable personalizations by setting the "Disable Self- Service Personal" profile option to NO
