However surely this type of thing comes up all the time, and there
are a whole bunch of widgets for which it would be pretty easy to
package a generator template for them.

Well, references to files will typically not be portable across
machines, so it doesn't seem such a common thing to persist in a
model... You can quite easily create a custom cell editor for your
type though:<br>
<ul>
<li class="toclevel-2"><a
href="http://wiki.eclipse.org/EMF/Recipes#Recipe:_Create_your_own_property_editor_in_a_generated_application"><span
class="tocnumber">3.1</span> <span class="toctext">Recipe:
Create your own property editor in a generated application</span></a></li>
</ul>
<br>
<blockquote cite="mid:j8p51i$jgl$1@news.eclipse.org" type="cite">
<br>
Is there some project that goes this extra step, and provides a
sort of widget layer on top of ecore?
<br>
<br>
(ps I am looking at some of the emf/gwt crossovers at the moment,
so that would be ideal)
<br>
<br>
Thanks
