Bug 484457

Description Michael Fritscher 2015-12-16 03:05:09 EST

Trying to use the snippet in https://bugs.eclipse.org/bugs/show_bug.cgi?id=484456 in a View's createPartControl leads to the message Could not create the view: Could not initialize class . If I click in "Details >>" it makes a big boom:

On RAP 3.0, I don't have exactly this problem, but in general clicking on "Details >>" on similiar errors worked.
