Hi,

although I'm working with Eugenia, I've posted a message in the
eclipse.modeling.gmf newsgroup, because I think my question is more
retated to GMT than to Eugenia. But, as I have no answer until now, I'd
like to confirm that the problem is a GMF one and not an Eugenia one.

Below I have reposted the question I previously wrote in the gmt newsgroup.

Thanks in advance,
To

Hi Toni,

At a first glance it looks like a GMF issue but I'll have a closer look
and get back to you.

Cheers,
Dimitris
