Hi,

I have a Node object with a [0..*] relationship to other Node Object.
Creating edges works fine. I have a problem in the delete action of this edge using an "Unset".

I tried to do that :

Begin
|_ Change Context var:element
|_ Unset (Feature Name = "etapes"; Element Expression = "[elementView.oclAsType(DEdge).targetNode.oclAsType(DNode).target/]")


index.php/fa/20207/0/

But it doesn't work and i don't know how to solve it.

Anyone can help me or tell me other solution to delete my relationship?
Thanks for the attention.

Hi,

THe change context should reference the edge source semantic element by
using the same expression you defined within the unset
"[self.sourceNode.oclAsType(DNode).target/]"

The unset "element expression" have to return a collection of elements
to unset from the feature (the edge semantic target in your case)

try with Element Expression =
"[elementView.targetNode.oclAsType(DSemanticDecorator).target/]"

Hi Florian, thanks for your answer.

I followed your instructions but i still have the problem with the following error message :
!MESSAGE Compilation error for expression [elementView.oclAsType(DEdge).targetNode.oclAsType(DSemanticDecorator).target/] : Unrecognized variable: (DSemanticDecorator)

I tried to do that :

Begin
|_ Change Context [elementView.oclAsType(DEdge).sourceNode.oclAsType(DNode).target/]

|_ Unset (Feature Name = "etapes"; Element Expression = "[elementView.oclAsType(DEdge).targetNode.oclAsType(DSemanticDecorator).target/]")


Thank you for your help.

Replace DSemanticDecorator by viewpoint::DSemanticDecorator; (the
acceleo parser needs of the package in this case)

That's strange. And if you replace DSemanticDecorator by a more concrete
type ? (DNode, DNodeList, following what is the real element behind)
