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 )
| Quote: | Hi all,
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

Hi Ivo
As you say, allInstances() 'does not work' it returns null; presumably
because you have some scoping problem that makes the model or its
conmtents inaccessible.
You'll have to hope that some GMF guy can help explain how to set up the
scope.
