| Calling eInstance on RCP fails [message #1385718] |

Hi,
I am working on an Eclipse e4 application and use a generated emf model. As long as I work under Eclipse directly from source there is no problem. But as far as I export my RCP and call MyFactory.eInstance nothing is going to happen. The factory isn't null, the code execution of this method just stops. The program itself doesn't hang up but as a result, all the button and menu items are disabled. I guess it is a dependency problem but there are no error logs or the like. So I have no idea what to do.
Greetings

Anduril,
It's impossible to diagnose the problem from your short description.
Note that you can remote debug an application. I.e., put lines like
this in your application's *.ini
-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8123
And attach to the process. You can set suspend=y to stop the process
very early (immediately) to see initialization, i.e., it doesn't really
start until you attach the debugger.
Most likely you've not included something in the build.properties for
binary bundles that are needed at runtime.

Thank you very much for your help! I wasn't aware of the remote debugging possibility and this really saved me a lot of time. The problem was, that I generated my EMF-Code into a src-gen folder instead of src. So it wasn't included in the binary build. I thought Eclipse would be more intelligent. Again thanks very much for your tip with the remote debugging which directly pointed me to that problem.
