VO got executed but is not showing the rows on the page the first time

Question

Hi, Below are my senario:
I have one jspx which contain a panel tab and 2 tabs inside it: tab A and tab B, under each tab is its own taskflow, jsff page, and its own AM and datacontrol also.
tab A have a table
tab b have a table with search panel. The view criteria that used to generate the search panel is not check "Run Automatically"
What I am trying to do is in tab A, user can select some rows and click one button, then below action happen:
1. the id of the selected rows will be pass to a AM method of tab B as string that separated by comma, and this AM method will execute the VO that the table of Tab B is based on
2. set tab b disclosure to be true to show tab B
3. The row that selected in Tab a will be shown in the table of tab b
Below are the code in the AM of tab b, it is exposed to client and it will be invoked by the button actionlistener of Tab A from the bean:
public void applyDashbaordViewCriteria(String listOfPS) {
if (listOfPS != null) {
PullSequenceSetupVOImpl psvo = this.getPullSequenceSetupVO2();
ViewCriteria vc = psvo.createViewCriteria();
vc.setName("PSDashboardVC");
ViewCriteriaRow vcRow = vc.createViewCriteriaRow();
ViewCriteriaItem vcItem =
vcRow.ensureCriteriaItem(PullSequenceSetupVORowImpl.PULLSEQUENCEID);
vcItem.setOperator(JboCompOper.OPER_IN);
vcItem.getValues().get(0).setValue(listOfPS);
vc.add(vcRow);
psvo.applyViewCriteria(vc);
psvo.executeQuery();
However my issue here is:
Whenever the first time entering the page, which will show tab A, I select some rows in the table and click the button, AM got executed correctly and before it leave above code, VO executed and row count is correctly match with what user selected in Tab A. However, the rows in the vo is not showing in tab B. Table in tab B show no rows.
Workaround for the issue:
If first time entering the page, I go to tab B first, without doing anything then come back to tab A, select some rows and click the button again, then this time, the row I selected start showing in the table of Tab B.
So my question is, how can I solved this issue to make the selected rows show in tab B without going to tab B to load the page first? Is that something to do with datacontrol scope?
I am using Jdev 11.1.1.3.0
Thanks.

Answer 1

Hi, now I think i know what is the root cause:
I overide executeQueryForCollection and executeQuery method in the VOImpl that table of Tab B is based on. And I notice the following:
Even when select row in tab A and click the button to call AM method to apply the view criteria and execute the query to return some row, when tab b loading the first time, I notice executeQueryForCollection is being fired again and invoked by executeEmptyRowSet.
It looks to me that even thought before the page load, VO already executed and have some row, somehow when ADF load the page, it will empty all the rows in the VO. And also since I have a query panel which I uncheck the Query Automatically. So even my applied view criteria still there, but VO will not get re executed again and show the result.
I think that is why this issue is happening. And also, that is why if I navigate to tab B first and come back to Tab A, now perform the same action, the selected rows start showing on the page.
Anybody can help me how can I resolved this issue? And also, I don't want to check the "Query Automatically" of the view criteria that I used to genreate the search panel because it may impact the performance.
