Bug 343445 [model] transient data does not notify
The new transient data map <String, Object> does not notify about changes and the owner contains a setTransientData(*) member. It should be more like org.eclipse.e4.ui.model.application.MContribution.getPersistedState() PW
bundles/org.eclipse.e4.ui.model.workbench/src/org/eclipse/e4/ui/model/application/impl/ApplicationElementImpl.java
return CONTRIBUTOR_URI_EDEFAULT == null ? contributorURI != null : !CONTRIBUTOR_URI_EDEFAULT.equals(contributorURI);
			case ApplicationPackageImpl.APPLICATION_ELEMENT__TRANSIENT_DATA:
				return transientData != null;
			case ApplicationPackageImpl.APPLICATION_ELEMENT__CLONABLE_SNIPPETS:
				return clonableSnippets != null && !clonableSnippets.isEmpty();
		}
		return super.eIsSet(featureID);
	}
	/**
	 * <!-- begin-user-doc -->
	 * <!-- end-user-doc -->
	 * @generated
	 */
	@Override
	public String toString() {
		if (eIsProxy()) return super.toString();
		StringBuffer result = new StringBuffer(super.toString());
		result.append(" (elementId: "); 
		result.append(elementId);
		result.append(", tags: "); 
		result.append(tags);
		result.append(", contributorURI: "); 
		result.append(contributorURI);
		result.append(", transientData: ");

		result.append(')');
