The Article:
http://www.eclipse.org/articles/Article-WorkbenchSelections/ article.html
contains an example plug-in that has the SelectionView class. There were
problems opening the view, so I thought perhaps the project was too old,
and I moved the view class into my own project (version 3.3.2).
Even after adding the view to my plug-in however, I got the following
error message:
"Error creating the view.
redo6_5.views.SelectionView"
Can someone explain what is going on? The extensions panel in the project
clearly shows that the class has been found when "browse" is used.
Here is the full error message for reference (it's quite long, and I
cannot make sense of it beyond the first line). Thanks in advance!
