generalization [message #49498]

Hi.
Having created simple gmf editor for UML.ecore i've got trouble
setting generalizations. For two classes A and B where A extends B my
editor generates following uml2 file

<?xml version="1.0" encoding="UTF-8"?>
<uml:Package xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:uml="http://www.eclipse.org/uml2/2.0.0/UML">
<packagedElement xsi:type="uml:Class" name="A">
<generalization general="#//B"/>
</packagedElement>
<packagedElement xsi:type="uml:Class" name="B"/>
</uml:Package>

And then UML Model editor fails to open it with this exception:

org.eclipse.emf.ecore.xmi.UnresolvedReferenceException: Unresolved reference '//B'. (platform:/resource/test1/test1.uml, 4, 37)
at org.eclipse.emf.ecore.xmi.impl.XMLHandler.handleForwardRefer ences(XMLHandler.java:1001)
at
org.eclipse.emf.ecore.xmi.impl.XMLHandler.endDocument(XMLHan dler.java:1066)

From the perspective of my editor this looks like generalization is lost
when diagram is being closed/opened.

Domain meta information properties of the corresponding Link mapping in my
gmfmap file are:

Containment feauture: EReference generalization
Element: EClass Generalization
Source Feature: not set
Target Feature: EReference general

Any help is highly appreciated as well as some explanation of what all
those Source/Target Features and their values
(general/source/target/specific, etc.) are.

wbr, eugen.

Eugen,

I looks like your editor is using the wrong resource implementation to
serialize your model - the resource implemenation in UML2 makes use of
UUIDs, but it appears that your resource does not.

Thank you for your answers. But i still can't find 'Invariant
Prefix' property anywhere to get sources generated properly... could you
please give some more hints where to look for it?

wbr,eugen.

Eugen,

The 'Invariant Prefix' generator model property will only be available for
UML2 generator models, i.e. models for which you have taken advantage of
some of the UML2-specific options when importing your UML model. One way to
ensure this it to press the 'Process All' button in the importer.

Once you have a UML2 generator model, the property will show up in the
Properties view when you have the generator model (root) element selected.
