[news.eclipse.modeling.gmt.amw] Re: dynamic attribute type

[Aram Hovsepyan <Aram.Hovsepyan@xxxxxxxxxxxxxx>]

        What I'd like to do is best shown by this example:

        class Modification
        {
                attribute type : EcoreType;
                attribute newValue : type;
        }

        so the newValue depends on the selected type. Of course, the sample above
is not correct. Is there any way to do this? This should be possible in the
weaving tool rather then in the further steps when I read the weaving
model.

        thanks in advance very much.

        regards,
                Aram.
