Re: [gmf-dev] problem with xsd derivated model and containment features

This kind of questions should be directed to http://www.eclipse.org/forums/index.php?t=thread&frm_id=16& instead of this list.
I believe the problem you're talking about is the same as described in https://bugs.eclipse.org/bugs/show_bug.cgi?id=146535

Hi i'm facing a problem when trying to specify a gmf solution for a
xsd-derivated emf model. This model generates wrappers for collections
that prevents setting the right containment feature ( the wrapper object
is resolved instead ) in a top mode reference (gmfmap file). The
wrappers are generated due to the xml is full of complextypes.
Next, i'll present the  case:

My xsd specifies the following  schema :

 <xs:element name="step">
   <xs:complexType>
     <xs:sequence>
       <xs:element ref="external-permissions" minOccurs="0" />
       <xs:element ref="actions" minOccurs="0" />
     </xs:sequence>
     <xs:attribute name="name" type="xs:string" use="required" />
     <xs:attribute name="id" type="xs:string" use="required" />
   </xs:complexType>
 </xs:element>

 <xs:element name="steps">
   <xs:complexType>
     <xs:sequence>
       <xs:element ref="step" maxOccurs="unbounded" />
     </xs:sequence>
   </xs:complexType>
 </xs:element>

 <xs:element name="workflow">
   <xs:complexType>
     <xs:sequence>
       ..
       <xs:element ref="steps" />
       ...
     </xs:sequence>
   </xs:complexType>
 </xs:element>

This schema allows specifying an xml like

<workflow>
<steps>
<step id=.../>
...
</steps>
</workflow>

When i derivate this schema to EMF, three Eclasses are created
WorkflowType, StepsType and StepType. The first have a reference to a
StepsType instance and this last has a list to StepType instances.Here,
the StepsType works as a decorator for the stepType list.

In my GMFmap specification, i set the WorkflowType as cambas' domain
meta element.  when trying to set the StepType container feature at a
top node reference, it is not available due to it is provided by
StepsType which actually is available.

How can i set indirections in containment feature of top node
reference ?

regards
