BUG: Null Pointer Exception

[kite]

OS: Windows XP with SP1
Eclipse: 3.0 M4
SWT-Designer: 1.2.0 Free Edition
Description:
I have created a SWT Application, select a layout , then add a sash form, add two components into sash form, if I delete one component , I can't add any component into sashform. Or add a composite into sashform(left component), then add a sashform into this composite, sometimes generated source has problem, for example, setWeights(new new int[] { -63, 287 }).

And if you create a Toolbar in a CoolItem, sometimes Designer will not work until you reopen it. In .log file you will see Null pointer exceptions .

How do see that you can not add new component? Do you see exception? Or cursor becomes disabled? Or you can add component, but it is placed in wrong position?

Or add a composite into sashform(left component), then add a sashform into this composite, sometimes generated source has problem, for example, setWeights(new new int[] { -63, 287 }).

Sorry, I can not reproduce this. Can you please provide more precise scenario?

And if you create a Toolbar in a CoolItem, sometimes Designer will not work until you reopen it. In .log file you will see Null pointer exceptions .

Can you provide error log here?
