Hello,
I posted my problem in GMF section, but there are no answers, so I decided to post it here too ( http://www.eclipse.org/forums/index.php?t=msg&th=152579& amp;start=0&S=0af8f2b4cf467d9a4c4284607c0496aa )

If few words:
a CompositeMode is part of my model, it can contain subModes and conditionalConnectors, a connection between these two nodes exists, but I want to allow such connection if both nodes are in one and the same CompositeMode.
I tried with the following target link constraint in the GMFMAP:
CompositeMode.allInstances()->exists(cm| cm.subModes->exists(sm| sm = self) and cm.conditionalConnectors->exists(cc| cc = oppositeEnd))
and this doesn't work because allIntances doesn't work for me, here are the debug logs:
[OCL] Evaluate: remes::CompositeMode
[OCL] Result : org.eclipse.emf.ecore.impl.EClassImpl@9cd7cd (name: CompositeMode) (instanceClassName: null) (abstract: false, interface: false)
[OCL] Evaluate: remes::CompositeMode.allInstances()
[OCL] Result : null
[OCL] Evaluate: remes::CompositeMode.allInstances()->exists(cm : CompositeMode | cm.subModes->exists(sm : SubMode | sm.=(self)).and(cm.conditionalConnectors->exists(cc : ConditionalConnector | cc.=(oppositeEnd))))
[OCL] Result : OclInvalid
[OCL] Evaluate: remes::CompositeMode.allInstances()->exists(cm : CompositeMode | cm.subModes->exists(sm : SubMode | sm.=(self)).and(cm.conditionalConnectors->exists(cc : ConditionalConnector | cc.=(oppositeEnd))))
[OCL] Result : OclInvalid
Please help me to fix this problem.
Thanks in advance,
Ivo
