Q:

Tosca - Java Exception while running Swing Application (JTree)

I am learning tosca and currently we are trying to run a regression test suite for a legacy Java Swing application.
My Test suite contains 4 modules (in JTree) and it is getting failed while clicking a node.
The Error I received on the module is,

at.tosca.javaengine.common.exceptions.ControlException: node or
  node-path not found! Detailed information contained in
  'JavaEngineException.txt above message is displayed in Executionlist

NOTE : The same Test suite is working in some other machine and not here. Both are same operating System. 

A:

The problem was TOSCA is faster than our application :)
Meaning: The frame was not loaded at the time when TOSCA was trying to scan the next page causing the error, the specific node was
 not found.
Solution: I added a TBoxWait with extra seconds, after that this is working fine.
