[news.eclipse.tools.hyades] Execution Flow does not show anything

["Shady" <sh_said@xxxxxxxxx>]

Hi ,
Iam using hyades to profile the PerformanceExample  tutorial. And everything
seemed to work and I can see monitoring is working and the following views
show data: Package Statistics,Class Statistics,Instance Statistics,Object
References.
However the Execution Flow view always show displays "No Data is
available,...) . I tried refreshing, restarting but it never showed data
No error logs are found either
What is wrong, or Iam missing something?
Please Advice
