[news.eclipse.platform.rcp] Re: Use Java-Code-Editor in an Dialog

[Johann Rosner <johann.rosner@xxxxxxxxxxx>]

Hello, now I have solved one problem. There was a problem with the 
plugin version. Now I can show the Dialog.

But the Dialog ist still uneditable! I have attached a screenshot and 
some code.

Have you an idea what's wrong?

Thanks in advance,
Johann Rosner
