[abbot-users] JTree Support

[xiaokun <xia...@gm...>]

Hi,

I launch the app with the Costello and do a click event on a tree node.Then
an exception is thrown and it will be blocked and stay wait status. In
normal case, when I click the node it will expand with several child nodes
got from database(the data is not stable). The app runs well without
Costello.
The Costello don't support this circumstance or it is a bug?




The Exception:
java.lang.NullPointerException
at javax.swing.JTree$AccessibleJTree.valueChanged(Unknown Source)
 at javax.swing.JTree.fireValueChanged(Unknown Source)
....
...
120308 02:34:53:759
abbot.script.EventExceptionHandler.exceptionCaught(EventExceptionHandler.java:22):
Unexpected exception while dispatching events:
