java.lang.ClassCastException when maximize mpart - exception

Question

I have a Eclipse E4 application with some different MParts. Now when I maximize the MPart by double clicking on its tab I got the ClassCastException. Also when I minimize it again, the same exception will be thrown. I looked at the error but could't find a place in my source where this exception can be thrown. Can someone help me with this? Below you can find the full stack trace of the error.

Answer 1

I found the issue. Some old code was still in my class to draw the a Nattable.
The code was a GridFactory that places the table on a grid. Removed this line fixed my problem.
