I have recently moved from Eclipse 3.0 to 3.1 (tried both M3 and M4). My
problem: From my RCP app, I am opening a new shell using the following
code:
Shell shell = new Shell(SWT.ON_TOP | SWT.CLOSE | SWT.TITLE | SWT.RESIZE);
shell.setBounds(100,100,640,480);
shell.setText("Title");
GridLayout layout = new GridLayout(1, true);
layout.marginWidth = 1;
layout.marginHeight = 1;
shell.setLayout(layout);
browser = new Browser(shell, SWT.NONE);
browser.setLayoutData(new
GridData(GridData.FILL_BOTH|GridData.GRAB_HORIZONTAL));
label = new Label(shell, SWT.NONE);
label.setLayoutData(new GridData(GridData.FILL_HORIZONTAL |
GridData.GRAB_HORIZONTAL));
label.setText("Single click selects elements.");
shell.open();
This used to work perfect in Eclipse 3.0. But in 3.1, the shell opens
empty, i.e. without any widgets. Could this be a bug in Eclipse 3.1 or is
something in my code "dirty" that Eclipse 3.0 used to tolerate, but 3.1 no
longer does?
Thanks for any advice!

Just some added Info to my problem that might be useful: the widgets that
are appended to the shell (in the example below a browser and a label,
though I tried all sorts of widgets and it doesn't make a difference) are
"technically" there, i.e. I can access them with getting Nullpointer
exceptions. For some strange reason they are just not drawn onto the
shell. P.S.: redraw & update don't help either.
Hm... It looks like a bug to me. Hopefully someone can comment on this!
Thanks in advance!

... I can access the widgets WITHOUT getting a Nullpointer Exception (just
correcting a typing error in my last post. sorry)

You are correct. As of 3.1, the behavior is consistent on all platforms.
