Mouse Navigation Problem in Forms 12c

@Michael Ferrante-Oracle We have very recently upgraded to forms 12c with the browserless webstart session option.  We are seeing an issue in some, but not all forms.  The issue is with selecting a field with the mouse vs. tabbing to that field.  Tabbing does not appear to be a problem.

Here are the specifics:

  1. Log in and go into the form
  2. Select, in this case, a drop down list item (LOV) within a list box with the mouse that is not the default item in a particular block.
  3. The cursor is in the item.  However, in this case the the list box is set to turn blue when a record is selected.  It is not blue.
  4. Select the List of Values button from the button bar and receive the error FRM-41026: Field does not understand operation, which is a message for a widget other than an LOV.
  5. If I hit TAB at that point navigation goes from the 1st item on the block to the next. 
  6. If I then mouse click a 2nd time in the LOV within the list box the cursor is there and the record is blue.
  7. Hitting the List of Values button at this point does what it is supposed to do.
  8. If I navigate away from that tab and back it starts all over again from item #2
  9. There is a when-tab-page-changed trigger on the form that designates per tab which item to do a go_item to - in this case the 1st item (intentional) which is a check box which IS set to keyboard and mouse navigable
  10. This was not a problem in 11g but now is in 12c forms
  11. This is not a problem in all screens, but I don't know the full scope of the damage as go live was 2 days ago.  It is repeatable in the screens it happens in that I have found.

What do I need to do to solve this?  I have messed with but really can't see any properties on the property pallets that seem to address this.

Could there be some web logic server level setting we are missing or is this something to be addressed in each form?

Any help would be much appreciated.

    which Version do you use

    Can you make a simple test case with a simple lov example to reproduce your case?

    I would like to check it on all three existing Versions.

    As Frank mentioned, having a test case would be extremely helpful.  Also, determining if the problem reproduces with Forms and Java 8u112 would also be a helpful data point.

    Regardless, you best bet is to work through Oracle Support.  If this is a defect, Support will be able to use your test case to confirm the issue and report the issue to development.
