Has ScrollBar different behaviour in SWT and RWT? [message #1064474]

Hello,

I found out, that ScrollBar has different behaviour in SWT and RWT. Strange to say, that ScrollBar´s behaviour in RWT is more correct as in SWT?!?!
The Problem:
With RWT the following code works as expected:

oScrolledForm.pack();
oScrolledForm.getVerticalBar().setSelection(100);

With SWT the following happens:
1) when I call pack() before setSelection(100), nothing happens, the scrollBar cannot be manipulated
2) when I DO NOT call pack() before setSelection(100), the scrollBar gets scrolled down, but the content in the ScrolledForm doesn´t scroll down.

What I do wrong?
Or is it a Bug?
Is there any workaround?

Thx

Hi Andreas,
as you don't have complaint about RAP behavior, maybe the RCP forum is a
better place to ask this question :-) . Please keep as informed if you
find something about the problem.
Thanks,
Ivan
