URGENT: executeQuery after setWhereClause causes infinite loop

Question

Hi,
- I'm using jdev 9.0.3.2.
- I have a JTable bound to a ViewObject.
- I set the vo's whereClause, the where clause has some syntax error.
- I call executeQuery
- The JBO exception is shown.
- I press ok.
BUT:
- The JBO exception is called again and again, the reason is getEstimatedRowCount called again and again by the repaint event.
I noticed the following code in JUIteratorBinding :
public void executeQuery()
synchronized(getSyncLock())
if (mIsAlive && mIsBound)
try
getRowSetIterator().getRowSet().executeQuery();
catch(Exception ex)
reportException(false /*markDead*/, ex);
reportException(false -> means do not markDead
is this OK?
Please help.
Thanks Ognian

You're hitting a reported bug 3090348
A known workaround is to reset the erring clause after execute and exception like:
private void setWhereClause_actionPerformed(ActionEvent e)
//here it starts
JUIteratorBinding ib=panelBinding.findIterBinding("EmpView1Iter");
try {
ib.getApplication().setErrorHandlerActive(false);
ib.getViewObject().setMaxFetchSize(100);
ib.getViewObject().setWhereClause("empno = xxx"); //the where clause
is intentional wrong!!
ib.executeQuery(); //one JBO exception is OK, but not an endless loop
until a stack overflow happens!
catch (JboException je)
ib.getViewObject().setWhereClause(null);
ib.getApplication().setErrorHandlerActive(true);
panelBinding.reportException(je);
ib.executeQuery();
//set a breakpoint here and go inside execute query
- this reports the exception once...
