How to resolve this error? [message #1059883]

Warn: The generic type associated with the 'DataCollection' classifier should have 1 type argument to match the number of type parameters of the classifier.
Error: The typed element must have a type

here is a picture of my model:
index.php/fa/14997/0/

i defined DataCollection as generic F, which extends GUID.
and all of these informations are defined
any ideas whats going wrong?

thanks in advance

I don't see a use of DataCollection in your screen shot. To specify the
type arguments at the point of use, ensure that Sample Ecore Editor ->
Show Generics is enabled, and use "New Child -> EGeneric Type Argument"
to create the arguments; they'll start out as a wildcard but via the
properties you can reference an EClassifier or an ETypeArgument.

I don't see what causes this error in the screen capture. Which typed
element doesn't have a type?

my model is pretty big, so i just copied the part, which i thought is of interest.
the model is split into two ecores. one defining the data classes and one defining my controller.

i cannot find ANY elements without type definition.
generics are enabled and i added them exactly the way you described above.

note: first i had one single ecore file which was generating with genmodel fine!
then i had to split it to data & controller
generating the data model for texo works fine.
but i do not even get the chance to generate the model with emf because it moans about the DataCollection (which was fine before i split up?!)

i compared the two ecores and cannot find any differences! (but references to the GUID, which is now in another ecore)

if you want i can email you the two ecore files (i am not allowed to put em here in the forum.)

The where is the error? If it's in the problems view, double clicking
it should navigate to the object with the problem...

The generator will turn to a tab with the problem indications, but you
can turn to the main tab and still generate. You can also tell it to
create problem markers, or you can invoke Validate on each Ecore model
in the Sample Ecore Editor which will also produce markers you can use
to locate the source of the problems.

You should be able to locate the problems using Validate in the editor.

both ecore files report no errors nor warnings when i call validate!
the genmodel shows me errors & warnings.

Hi

Are you using the right Validate? If you have WTP installed, it
contributes another absolutely useless menu entry; almost seems designed
to cause trouble.

arr, you are right, there are two validate (did not notice that until you point me on it now :-/)
as i now use the right one, i get pointed to the error.
and was able to resolve it within minutes (i lost some days due this damn second validate entry)

thanks for your help ed.

isn't it possible to remove the other validate when EMF is open? RFC *hint.hint* (i do remove other generated menues etc in my app too)

or call the emf validate different (eg validate EMF model?)

Hi

I couldn't possibly comment further than observing the date on which
https://bugs.eclipse.org/bugs/show_bug.cgi?id=197617 was raised.
