Hello Lorenzo,
Hello Vincenzo,
Hello Parsley team,
Hello users,
I already posted this issue in the EMF forum without any responses
I'm completely stuck since several days with an OSGI NoClassDefFoundError exception
I have RAP application using Parsley deployed with equinox.
I'm doing a custom contextual menu with emfMenus exactly like described in the documentation.
Here is my code for the GuiceModule
module com.merckgroup.bio4c.deviceshape.editor.signal extends ViewEmfParsleyGuiceModule {
parts {
viewpart com.merckgroup.bio4c.deviceshape.editor.view.signal{
viewname "Signal Editor"
viewclass SignalSaveableTreeFormView
}
}
/*
FIRST TEST WITH SAME ISSUE
menuBuilder{
emfMenus{
Signal s -> #[
actionChange("Add a reference", s,
[
signal |
val ref = ReferencesFactory.eINSTANCE.createSignalReference
ref.^label = "REF:"+s.name
])
]
}
}*/
bindings{
type ViewerContentProvider -> SignalContentProvider
type EditingMenuBuilder -> SignalMenuBuilder
}
}
Here is my EditingMenuBuilder
public class SignalMenuBuilder extends EditingMenuBuilder {
public List<IMenuContributionSpecification> emfMenuContributions(final Signal s) {
DeviceShape deviceShapeLoaded = (DeviceShape) RWT.getUISession()
.getAttribute(DeviceShapeConfigurations.DEVICE_SHAPE_LOADED);
//HERE I do not have the issue the ChangeRecorder is found by the class loader
ChangeRecorder changeRecorder = new ChangeRecorder();
final IAcceptor<Signal> _function = (Signal signal) -> {
var ref = ReferencesFactory.eINSTANCE.createSignalReference
ref.setLabel("New Ref");
signal.getReference().add(ref);
}
};
IMenuContributionSpecification _actionChange = this.<Signal>actionChange("Add a new reference", s, _function);
return Collections.<IMenuContributionSpecification>unmodifiableList(
CollectionLiterals.<IMenuContributionSpecification>newArrayList(_actionChange));
}
When I'm right clicking on my tree and clicking on the action I do have the following stack trace :
!ENTRY org.eclipse.rap.ui 4 0 2021-05-03 22:56:42.852

Has someone get an idea when I'm facing this issue ? Is this a problem with the packaging of org.eclipse.emf.edit or something like that ?
Did someone already faced this issue or can someone can guide me ?
Is there in the example project an example for menuBuilder to try if I have the same issue ?
Thanks a lot,
JB
