Why does my link disappear? [message #223923] Wed, 01 April 2009 15:53 Go to next message

I've defined a node State and a link StateLink in my xsd:
<xsd:complexType name="State">
<xsd:attribute name="name" type="xsd:ID" />
</xsd:complexType>

<xsd:complexType name="StateLink">
<xsd:attribute name="name" type="xsd:ID" use="required" />
<xsd:attribute name="fromState" type="xsd:IDREF"
ecore:reference="sc:State" />
<xsd:attribute name="toState" type="xsd:IDREF"
ecore:reference="sc:State" />
</xsd:complexType>

I can draw my states and my links, they are displayed and the XML is
correct.
<state name="State 1" task="Task 1"/>
<state name="State 2" task="Task 2"/>
<stateLink fromState="State 1" name="Test" toState="State 2"/>


When I reopen the diagram, the links are not displayed any more and when I
save the file again, my links have no fromState and toState attributes any
more:
<stateLink name="Test"/>

What am I doing wrong?

Thanks,
Peter

Hello Peter,

Can you open this file using EMF-generated editor? Can you see correct link
there?

Thank you, Alex!

It seems to work now, but I don't really know why...

It did work in EMF-Editor before, but GMF did not seem to understand the
Links correct after reopening.

Even though it works now, can anyone tell if my previously posted
configuration is ok?
