Internal error when trying to open an aird file [message #1697464]

Hi all,

When opening my aird file I'm getting the following error: An internal error occurred during: "Loading models". The stack trace can be found below [1].

The last modification has been made by a colleague of my and it seems that he's still using the Luna SR1 release while I'm using the Luna SR2 release. We didn't expect that within the Luna release this should give us problems. So any idea what can be the issue and how to solve it?

[1] The complete strack Trace:

It seems that the model is modified during the resolveAll done by Sirius:
org.eclipse.xsd.impl.XSDSimpleTypeDefinitionImpl.createFundamentalFacets(XSDSimpleTypeDefinitionImpl.java:3037)
at
org.eclipse.xsd.impl.XSDSimpleTypeDefinitionImpl.getCardinalityFacet(XSDSimpleTypeDefinitionImpl.java:3000)

A getter try to complete the model before returning the value.

It seems you use a metamodel based on xsd, did you make some changes in
your metamodel ?

Hi Maxim,

The metamodel is in an ecore file, but what we did (and since then we are having problems) was exporting it to an XSD scheme in order to use it in another tool.

Is it possible that the XSD exporter (xml - xsd schema definition SDK) is causing problems?

Cheers
Steven

Hi, did this one get resolved? Am getting the same error message with trace... The error occurs when I open the modelling perspective.
