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

[Johann Rosner <johann.rosner@xxxxxxxxxxx>]

Hello i have tried your solution. But I failed!

I have appended my code (code.txt).

My problems are:
- sourceViewer.configurer(...) takes infinite time. The method never 
return. I don't know why. Any idea?
- The sourceViewer isn't editable. Can i change this? (2) doesn't work.
- How can i (in code) insert Text into the sourceView?
