[EMFForms] TableControl Master/Detail Error [message #1619661] Mon, 16 February 2015 13:54 Go to next message
Eclipse UserFriend
Hello,

I generate a ecore model from a xsd. I get follow error when i create TableControl with a panel. If you click the + button, the error will occur.

All projects+models are attached.
The Problem is the Position-->Length object in the detail view, but i don't understand the problem.
The Preview in eclipse ide works.

Anyone have an idea what is wrong?

The Problem is in VFeaturePathDomainModelReferenceImpl the rootEObject is wrong. This the rootEObject from the view not from the panel view. Bug?
	EObject iterateEObject = rootEObject;
		for (final EReference eReference : getDomainModelEReferencePath()) {
			relevantChange |= eReference.equals(notification.getStructuralFeature())
				&& iterateEObject == notification.getNotifier();
			if (relevantChange) {
				break;
			}
			iterateEObject = (EObject) iterateEObject.eGet(eReference);
		}



EDIT: If i use a viewmodel in a seperate file then it works

Hi Dennis,
you found a bug in emfforms. The detailView is not resolving correctly.
You already found the solution, using a seperate view model. This is actually the preffered solution because we will remove all inlined detailViews with the next major release.

Cheers,
Eugen
