LOV (attribute updatable while new)

Question

hi,
I have a question about the following code :
// jButton1.setModel(PanelLOVPersonView.createLovBinding(new JUPanelBinding("sec100.MypackageModule", this), jButton1, "UsrdefPersonView", null, "UsrdefPersonViewiewIter", new String[] {"Perid"}, "LOVPersonView", new String[] {"Perid"}, new String[] {"Surnam", "Fstnam", "Bldabbr", "Offnum", "Phnnum"}));
// jButton1.setModel(PanelLOVPersonView.createLovBinding(new JUPanelBinding("sec100.MypackageModule", this), jButton1, "UsrdefPersonView", null, "UsrdefPersonViewiewIter", new String[] {"Usrnam"}, "LOVPersonView", new String[] {"Usrnam"}, new String[] {"Surnam", "Fstnam", "Bldabbr", "Offnum", "Phnnum"}));
"Perid" and "usrnam" or both attributes from a view object ("UserdefPersonView")
that are Updatable while new. If i run my jclient frame then the LOV button is disabled when i am on an existing row.
But if i replace the above code with the following:
jButton1.setModel(PanelLOVPersonView.createLovBinding(new JUPanelBinding("sec100.MypackageModule", this), jButton1, "UsrdefPersonView", null, "UsrdefPersonViewiewIter", new String[] {"Perid", "Usrnam"}, "LOVPersonView", new String[] {"Perid", "Usrnam"}, new String[] {"Surnam", "Fstnam", "Bldabbr", "Offnum", "Phnnum"}));
then this feature does not happen,
does anybody know why?
And how we can make it work if we want to fill in both from the LOV?
thanks,
Bert.

Answer 1

thank you very much for the answer it helped a lot.
I wanted to disable a lov button when i was on an existing row and enable it when i am on a new row.
c the code below.
This mostly works but sometimes it doesn't.
When i startup the frame there is an automatic query so i am on an existing row but the lov doesn't get disabled. The same when I insert a row and do a rollback.
I can see (from the println) that the code gets executed (first the "navigated" and then the "rangeRefreshed".
This is what i get from the System.out.printlns :
navigated
false -> so it gets disabled
rangeRefreshed
true -> but here it is enabled?
So the lov has been enabled again between the navigated and the rangeRefreshed.
Is this the expected behaviour?
thanks,
Bert.
Ps: Your code to enable/disable the comm works correctly.
panelBinding.findIterBinding("EmpViewIter").getRowSetIterator().addListener(new oracle.jbo.RowSetListener()
* Invoked when the range changes.
* @param event a description of the new ranges.
public void rangeRefreshed(oracle.jbo.RangeRefreshEvent event){
System.out.println("rangeRefreshed");
System.out.println(jButton1.isEnabled());
public void navigated(oracle.jbo.NavigationEvent event)
System.out.println("navigated");
oracle.jbo.Row r = event.getRow();
// if (row != null)
oracle.jbo.domain.Number n = (oracle.jbo.domain.Number)r.getAttribute("Deptno");
if (n != null && n.intValue() == 30)
mComm.setEnabled(true);
labelComm.setEnabled(true);
else
mComm.setEnabled(false);
labelComm.setEnabled(false);
// oracle.jbo.domain.Char c = (oracle.jbo.domain.Char)r.getAttribute("RowState");
String c = (String)r.getAttribute("RowState");
if (c !=null && c.equals("NEW"))
jButton1.setEnabled(true);
else
jButton1.setEnabled(false);
System.out.println(jButton1.isEnabled());
});
