- AssertionFailedException in TreeViewer on Mac -
Should it be possible to use JFace elements withtout using a
JFace-application?
On windows it works without problems and on a Mac "most" of it works.
Here comes the only problem weŽve found (until now):
When the user opens a node in a TreeViewer and later collapses that node,
the program crashes with an Assertion FailedException ("assertion failed:
The application has not been initialized").
Since it looks like an assertion i was hoping, that "-disableassertions"
or "-disablesystemassertions" might work, but nothing changed (why?).
Ideas for an easy solution?
(Building a snippet takes some time, since iŽm the developer (only working
on Windows) and my colleague is able to test if the snippet does what itŽs
supposed to do).

The exception was not caused by the fact, that i used JFace elements
directly in a Shell!
Every exception that occurs in a standalone JFace application,
is accidentally converted in an AssertionFailedException, if you
use a runtime.jar version thatŽs too old.
(fortunately i found a description of this problem in Googles cache,
i didnŽt find a hint in the eclipse newsgroups).
I donŽt know in which version this was fixed, but at least 3.1M4 handles
exceptions correctly! :-)
It worked in Windows and didnŽt work on Mac because there is a different
behaviour for selection-change-event in a tree.
In Windows you always get a not empty array of selected TreeItems,
on a Mac this array can be empty!
