Rectangle rect = (Rectangle) super.getConstraintFor(request, child); Rectangle cons = getCurrentConstraintFor(child); if (request.getSizeDelta().width == 0) rect.width = cons.width; its reasonable to expect that rect != null However there are reasonable usecases when getCurrentConstraintFor(child) == null, causing NPE here
Created attachment 205453 [details] trivial - fixes NPE
Is there an ETA when this fix will be available? Which GMF/Eclipse version can we expect this fix to be in? Thanks Markus
Hi, I just commited the fix. If the tests are running well also on server it will be part of Eclipse Juno. regards,
tests passed
Thanks, Aurelien
