Hello,

The problem occurs in a form with a tree item. At random times (during runtime) the form freezes and the java console shows the error:
  java.lang.IllegalArgumentException: oracle.forms.ui.TreeDataSource.getData(): illegal index

VERSIONS used:
 - Forms-applet 10.1.2.3.
 - Java Plug-in 1.6.0_12
 - Using JRE version 1.6.0_12 Java HotSpot(TM) Client VM

This seems to be a known/common problem (search on the internet) but the solution is not clear.

What can i do to solve this?

Thanks in advance!

Hans
