[news.eclipse.platform.rcp] Error in Eclipse 3.4 using TreeViewer

[inaarya@xxxxxxxxxx (Ina )]

Hi All,

I am using TreeViewer in Eclipse3.4.When I try to expand the node, I am 
getting dummy value instead of child nodes. I explicitly defined in my 
code that is getChildren length is 0, then add the nodeType as "dummy". 
But instead I should get the nodes in my case as the child nodes should 
exist. I am getting error in the Error Log as beloW:

Ignored reentrant call while viewer is busy. This is only logged once per 
viewer instance, but similar calls will still be ignored.

The exception trace seems as below:

java.lang.RuntimeException
at org.eclipse.jface.viewers.ColumnViewer.checkBusy(ColumnViewer.java:763)
at org.eclipse.jface.viewers.ColumnViewer.refresh(ColumnViewer.java:530)

The same code I was using with Eclipse 3.3 but it is working fine and 
showing 
all the children values as expected.
My Eclipse 3.4 version details are as below:

Version: 3.4.0
Build id: I20080617-2000

Please help me out in resolving this issue.

Thanks!
Ina Arya
