[news.eclipse.modeling.m2m] Re: [ATL][UML] set stereotyped tagged value

["James Bruck" <jbruck@xxxxxxxxxx>]

Hi Ivano,

>From  the stack trace it looks like there is an exception coming from the 
application of the Stereotype but you mention that the error is from the 
setting of the 'type'  value;  is the problem with the application of the 
Stereotype itself?  The Element.applyStereotype() will throw 
IllegalArgumentExceptions if the stereotype had previously been applied or 
if the extension or definition could not be found.

In general, setting a tagged value to a Stereotype is not currently 
supported since you could run into problems if the Profile gets updated. 
If you are not worried about migration issues, then it should work.      I 
believe a defect already exists on that issue.

Cheers,

- James.
