Hello!
I've installed the new LinuxMint 16 64bits., and the Eclipse Kepler JEE SR1 package, and also the WindowBuilder from the official update site via Eclipse IDE.
I have a great problem of not being able to create windows with Design option.
The error I am facing with is:
org.eclipse.wb.internal.core.utils.check.AssertionFailedException: No special container association and no component creation association for {new: org.eclipse.swt.widgets.Shell} {local-unique: __wbp_shell} {/new org.eclipse.swt.widgets.Shell(org.eclipse.swt.SWT.NONE)/ /__wbp_shell.setLayout(new org.eclipse.swt.layout.RowLayout())/} and {new: org.eclipse.swt.widgets.Shell} {local-unique: no-variable-yet} {}

I have spent hours with different combinations of Eclipse's (from Juno to Luna), but I cannot make the problem gone. I have removed the complete openjdk stuff and replaced with oracle's java, still no way to solve. I am working nearly a year with WB, but I could hardly find a proper Eclipse+WB match, which is a desolating fact.
I don't understand why is WB so fragile? Are there any viable solutions for this error?
I would really appreciate your answer!

I'm glad you got it working. That it ended up being an issue with a window manager does not surprise me at all. There are lots and lots of Linux window managers and many of them have serious flaws. Almost any of them can break update to update, so it is quite a minefield from our POV.
WB needs to render the live widgets off screen in order to get the WYSIWYG images you see in the design view. If the window manager fails to render them, you get nothing in the design view. What I have typically seen happen is that the window managers decides to disable off screen rendering as an "optimization". That often happens in one update and is reverted in the next once the authors of that window manager get enough complaints and realize their "optimization" actually breaks stuff.
