whenever i try to connect an EType the object selection dialog does not show any objects...

this was working earlier today. restarting eclipse did not solve the problem

any ideas how to solve this?

PS: note that in the ecore properties i get the correct objects in the dropdown.

Ludwig,

What do you mean by the selection dialog verses the ecore properties?
Are you both referring to the properties view? Are you editing an Ecore
model or your own model?

on an open ecorediag file, when i select a class,
go to properties view -> model -> EType. the list of selectable items contains only null
whereat if i have the ecore open and select the same property, i have the full and correct list to choose from.

additionally i noticed that renaming classes sometimes leads into invalidity (class gets renamed but not updated in the ecorediag model)

Do you mean when you select an attribute? An EClass doesn't have an
EType property.

I tried this myself just now and it works fine for me.

They'd need to be a bit careful that all proxies are resolved, because
proxy URIs for Ecore use the name of the class in the fragment path.
I'm not sure if they're being careful about that.

i know that an Class can't have a EType, as it is an etype itself Wink

Wink

i meant, when i select a function, which returns an EType (if you dont set one its void...) and i am not able to select that in diagram
(NOT ON ALL OBJECTS - but sometimes it simply disappears - happened now a few times - i do not know what it causes...)

Ludwig,

Yes, I see the same problem looking at the Change model. It looks like
there's a bug you'll need to report. There's really no support for
generics either.

I suppose you'll need to open the underlying Ecore resource to change
these things, and to work with things that involve generics. :-(

the generic does not work in ecore either... for me

reporting a bug is no problem, but reporting the bug so people understand what i mean might be the problem (as it took 3 posts to show you what i meant)

Ludwig,

Be sure that "Sample Ecore Editor -> Show Generics" is enabled. You
won't be able to edit generics without that.

Try to create as simple a model as possible and explain the exact steps
to see the problem. Someone should be able to load your model into
their workspace (so exporting a project containing the example that they
can import into their workspace helps), and click on a few things to see
the problem.

Ludwig,

You've opened the *.ecore resource directly? With what editor?

omg - iam blind?!

ok, there is the menue, but show generics is already checked and i do see the option EType Parameter, but the list is empty.

ah wait - i have to create a new child to be able to edit it...

the workflow in EMF could be optimized Wink

Wink

some things should be created by default as creating every bit takes ages.
eg. to create a body for a function you first need to create eiter a documentation for it or include the correct annotation source for it.

So you've selected an EGenericType and for that you can set either the
EClassifier or the ETypeParameter. You'll only have the choice for
ETypeParameter if the containing EOperation or EClass defines an
ETypeParameter, which likely you don't have. On an EGenericType whose
classifier is one that defines ETypeParameters, like EEList does, you'll
be able to use the context menu on that EGenericType to create a
contained EGenericType (which represents an argument) and for that
EGenericType you'll be able to specify an EClassifier or ETypeParameter.
