Description Elias Volanakis

2011-02-16 18:57:58 EST

The method disableEclipseProgressManager() in AbstractApplication causes an NPE and prevents startup. Seen with the 3.7.M5 target.

Reproducible with: 

- Mail Sample (Riena UI)
- Riena Demo Client

Reason is that there is no Display when this is called.

Stack trace:

java.lang.NullPointerException

Could reproduce the problem running the Riena Demo Client.

Added the Method void initializeUI() in AbstractApplication as a hook to create the PlatformUi Display instance. 
Implemented in SwtApplication.

Heiko, das hat nicht geholfen. In RAP bekomme ich noch folgende Exception:

java.lang.NullPointerException

I try to reproduce ..

Comment 6 Nobody - feel free to take it

Can reproduce the bug under RAP

I now use the RapDetector to check if RAP is available before disabling the ProgressManager. Behaviour of ProgressManager in RAP and indigo RCP is different concerning registration of job listeners.
Code now works for rap and rcp.
