Re: [e4-dev] Nullpointerexception when launching a clean e4application project
|
I just checked and it looks like we are NOT writing out a warning about
the fact that we have no DS running.
I think we should try to look up one of the DS-Services we know and in
case it it NULL we print out a warning message saying DS is not running,
and exiting the launch.
