Hello there,
I have an ecore model, read from schema.
I have a question about this structure:
Model
package Core
class CmisPropertiesType
Package Messages
class CreatedocumentType
property properties of class CmisPropertiesType
In Ecore this all look well.
When I convert to UML the property shows up as :
<<eReference>> <property> properties
and the association is set to
Association <Association> A_properties_createDocumentType
In this assoc the member end is set to:
Member End <<eReference>> <Property> properties, <Property> createDocumentType : CreateDocumentType
It seems that I have somehow lost my reference to the CmisPropertiesType and end up with a loopback association to CreateDocumentType.
When i look at it in text it looks like:
<ownedAttribute xmi:id="_JNucdFEREd-RXfSJpGgrjw" name="properties" isOrdered="true" aggregation="composite" association="_JNuchVEREd-RXfSJpGgrjw">
<type xmi:type="uml:Class" href="CMIS_Core.uml#_JOBX_lEREd-RXfSJpGgrjw"/>
</ownedAttribute>
Where this id can't be found in file CMIS_Core.uml (in fact all reference-ids to this file begin with _JOB. which is not in the file. ( the equivalent reference in the exported ecore file can be found in the CMIS_Core.xmi file)
Is this expected behaviour?
Best Regards,
Mobius

Hi, Mobius,
Sorry, I didn't understand from your first post that the type of the
"properties" attribute wasn't resolved: it wasn't clear to me what the
XML snippet was indicating.
If you have cross-document references, then you need to ensure that all
of your documents are converted to UML in one step, otherwise I suppose
badness will happen. I take it this is what you are doing? If so, then
probably you have a test case for a bug report. There shouldn't be
anything you can specify in a wizard that results in malformed outputs. :-)
Cheers,
Christian

Christian,
In ecore:
EType CmisPropertiesType
in UML:
Type <Class>
I would expect class CmisPropertiesType in the UML.
Somehow the info is retained, because there is a (wrong, see post) reference to the other uml file in the xmi.
I understand I mistook the referce member end for some sort of loopback ( which it actualy is!), but still I think the type in uml should be CmisPropertiesType.
The link into the 'other uml file' gets lost because the xmi:id of the referenced class gets scrambled.
Bug!! or what???
BR,
Mobius
