I have set the data context on a widget.
The data context is a dynamic emf model.
When loading the xwt form, I will get this error:

Caused by: java.lang.IllegalArgumentException: Could not find property with name connectionid in class class org.eclipse.emf.ecore.impl.DynamicEObjectImpl
at org.eclipse.core.internal.databinding.beans.BeanPropertyHelp er.getPropertyDescriptor(BeanPropertyHelper.java:177)

at org.eclipse.e4.xwt.jface.XWTObservableWrapper.checkDelegated (XWTObservableWrapper.java:202)

It seems that the correct data provider is not recognized. XWT is using the object data provider instead of the EMF data provider.
The ..xwt.emf plugin is available in the runtime and is added to the required-bundles header in my plugin.

You need to call EMFBinding.initialze() before use XWT It register the EMF
data provider..
