[news.eclipse.platform.swt] Re: Windows fires SelectionEvent on tree.set

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

Looks like a timing issue or are do doing something with 
Display#asyncExec()? From what you say I construct the following.

You've got a TextWidget and TreeWidget and when entry text you are 
updating the selection in your Tree and the other way round, right?

I guess we need some code to reproduce this. You should try to write a 
small snippet you can paste here and we can run.
