Hi,
I have some trouble getting EMF Forms running inside an SWT Application. I followed the hints at eclipsesource.com/blogs/tutorials/emf-client-platform-how-to-customize-the-editor-layout/#embbededitor but when I try to show a EMF Forms based view inside a composite of my SWT test application I get a NullPointerException.
Exception in thread "main" java.lang.NullPointerException
at org.eclipse.emf.ecp.view.spi.provider.ViewProviderHelper.readViewProviders(ViewProviderHelper.java:55)
at org.eclipse.emf.ecp.view.spi.provider.ViewProviderHelper.getViewProviders(ViewProviderHelper.java:48)
at org.eclipse.emf.ecp.view.spi.provider.ViewProviderHelper.getView(ViewProviderHelper.java:109)

at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3759)
at amelie.ui.swt.app.Main.main(Main.java:55)
The part where I call ECPSWTViewRenderer looks like this:
Method eobject = new Amelie_modelFactoryImpl().createMethod();
eobject.setName("New EObject");
ECPSWTViewRenderer.INSTANCE.render(MainView.getMainComposite(), eobject);
The project dependencies are:
* org.eclipse.swt
* org.eclipse.emf.ecp.ui.view.swt
* org.eclipse.emf.ecp.view.model.provider.generator
* org.eclipse.emf.ecp.view.model.provider.xmi
* My Ecore project
* My Ecore.edit project
I'm definitely missing something here but I can not find any decent documentation on this topic.

Hi,
just to be sure: Ia your final goal a non-OSGi application? This use
case is currently not supported, as EMF Forms relys on extension points
provided by core.runtime. In general it would be possible to provide a
plain Java version, too, but we would to refactor a bit for that.
If you want to be based on OSGi, then not the dependencies are the
issue, but the run configuration (which decides which bundles are
started). To get a running run configuration, I propose you start with
the feature based configuration as described in the getting started
tutorial and add your bundle to it. This way you make sure everything
required is in.
Best Regards
Jonas

I am curious: What is the reason you want to avoid OSGi? It could also
be considered as a main advantage :-)
I am not sure, whether you will get happy with a RCP application without
using OSGi, too.
Best regards
