Child Reference Containment Feature [message #216106]

I want to place a Node(NodeA) inside a Compartment(Slice). But I get the
error message "'Containment Feature' must be owned by 'Domain Meta
Element' or its super type of this reference parent Node Mapping".

Does any one know how to solve the problem?

The class model is as follows:

class Network contains:
- nodes:NodeA (Containment)
- slices:Slice (Containment)

class NodeA
- network:Network (Reference)
- slice:Slice (Reference)

class Slice:
- nodes:NodeA (Reference)
- network:Network (Reference)

The top node reference at gmfmap file looks like this:

<nodes>
<containmentFeature
href="psc.ecore#//Network/slices"/>
<ownedChild>
<domainMetaElement
href="psc.ecore#//Slice"/>
<labelMappings>
<diagramLabel
href="psc.gmfgraph#SliceCompartmentLable"/>
</labelMappings>
<tool
xsi:type="gmftool:CreationTool"
href="psc.gmftool#//@palette/@tools.0/@tools.2"/>
<diagramNode
href="psc.gmfgraph#SliceContainer"/>
<children
compartment="//@nodes.1/@ownedChild/@compartments.0"
referencedChild="//@nodes.1/@ownedChild/@children.0/@ownedChild ">
<containmentFeature
href="psc.ecore#//Network/nodes"/>
<ownedChild>
<domainMetaElement
href="psc.ecore#//Node"/>
<tool
xsi:type="gmftool:CreationTool"
href="psc.gmftool#//@palette/@tools.0/@tools.1"/>
<diagramNode
href="psc.gmfgraph#SliceNode"/>
</ownedChild>
</children>
<compartments
children="//@nodes.1/@ownedChild/@children.0">
<compartment
href="psc.gmfgraph#SliceContainerCompartment"/>
</compartments>
</ownedChild>
</nodes>

Hello Martin,

instead of:
> <containmentFeature href="psc.ecore#//Network/nodes"/>

you have to use:
<containmentFeature href="psc.ecore#//Slice/nodes"/>

(if Slice/nodes reference is a containment reference).

Hi Alex,

no unfortunately Slice/nodes is not a containment feature. The containment is Network/nodes.
A modified solution from posting "Shortcut for 1:1:n containment reference chains in
NodeMapping/ChildReference" should help me.

thanks, Martin

Hello Martin,

In this case you can still specify Slice/nodes as a containment feature,
ingnore warnings, do generate code and then modify generated code (corresponding
creation command) to put newly created node into the proper containment feature.
