Hi Malu,
I haven't seen this issue before, but none of the debug views use the expandAll(), method so it's possible that you've come across something new.  Can you open a bug against debug platform and attach a snippet demonstrating the bug.

Thanks,
Pawel

Hi All,

 

We have implemented a tree viewer using TreeModelViewer (Virtual type in Lazy mode). I could see a strange behavior while running in Linux OS . If ever I try to expand the tree items using the  API expandAll(), the tree starts blinking/flickering, if it fail to fetch the child nodes. But this behavior was not there in Windows.

 

I tried to debug the code, but it went deep into some infinite loop that always try to update the tree viewer. Please see below the relevant stack trace :

                ViewerUpdateMonitor$1.runInUIThread(IProgressMonitor) line: 99      

                UIJob$1.run() line: 95    

 

Will it be any problem with our implementation ?

 

Please guide me on how I should proceed further.

 

Thanks in Advance,

Malu..
