Profile with enumeration in same file as model -> ClassCastException [message #470230] Fri, 09 February 2007 11:23 Go to next message

Hi,

I have a Model on which I apply a Profile. The model and the profile and
saved in the same unique file.
The profile defines a stereotype with a property whose type is an
enumeration, defined in this profile as well.
This stereotype is applied to an instance of the model, an the property is
set to an enumeration literal.
No problem to save this model. The file format looks good, all necessary
information is there.

But I get a ClassCastException when a reload the resource.
This is because the resource is loaded using
XMLResource.OPTION_DEFER_IDREF_RESOLUTION=true (in UMLResourceFactoryImpl).
By the time the xmi reader try to set the value of the property, the type
of this property is not already set (forward references are not resolved,
we did not reached the end of the document).

I suspect this problem would be solved by saving this profile in another
resource, but I need the ability to save the model and the applied profile
in one unique file.

Using Eclipse 3.2.1, EMF 2.2.1, UML2 2.0.1.


Here is the uml model:

Hi Sebastien,

Hi Sebastien,

I'm seeing this stack trace..

With slight modifications I can open the model and can see the following .



Please raise a defect and this will be taken care of.

Thanks for the quick answer.

Bug reported:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=173843

My current workaround is to call resolveForwardReferences() in UMLHandler:

protected void processTopObject(EObject object) {

// DynamicEObject -> resolve forward references
if (object instanceof DynamicValueHolder) {
handleForwardReferences();
}

super.processTopObject(object);
}

This assumes stereotype applications appear in the file after the profile,
which is true in my case.
I hope I don't break things by adding this...

Sebastien,

Yes, putting profiles in the same resource as models can only work if the
profiles appear before the models. Note that the problem you are seeing
happens regardless of whether idref resolution is deferred or not - as
you've suggested, we'll need to ensure that forward references are handled
after each profile has been parsed, to ensure that their metadata has been
completed processed before potentially being used in the model that follows.

Hi Sebastien,

I'm seeing this stack trace..

With slight modifications I can open the model and can see the following .



Please raise a defect and this will be taken care of.

Regards.

Thanks for the quick answer.

Bug reported:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=173843

My current workaround is to call resolveForwardReferences() in UMLHandler:

protected void processTopObject(EObject object) {

// DynamicEObject -> resolve forward references
if (object instanceof DynamicValueHolder) {
handleForwardReferences();
}

super.processTopObject(object);
}

This assumes stereotype applications appear in the file after the profile,
which is true in my case.
I hope I don't break things by adding this...

Sebastien

Sebastien,

Yes, putting profiles in the same resource as models can only work if the
profiles appear before the models. Note that the problem you are seeing
happens regardless of whether idref resolution is deferred or not - as
you've suggested, we'll need to ensure that forward references are handled
after each profile has been parsed, to ensure that their metadata has been
completed processed before potentially being used in the model that follows.
