Hi all,
In my GMF-based project, I wanted to have a model element with a
reference to another element that was part of my development environment.
This was possible, but I was having a problem with the 'href' attribute
automatically turning relative, rather than an absolute
'platform:/plugin/xyz/...', which it should have been.
Eventually, I found out that the solution for GMF was to modify
XXXDiagramEditorUtil.getSaveOptions(), and add the line:
saveOptions.put(XMLResource.OPTION_URI_HANDLER, new
URIHandlerImpl.PlatformSchemeAware());
Perhaps this could be added as an option to .gmfgen? I've implemented
this as a dynamic template for my project [1], but I think it is a
fairly common request, and the dynamic template is fairly fragile.
Hope this helps someone else :)
Cheers
Jevon

Jevon,
Why do you feel is "should" be absolute? It actually works fine to be
relative...

Hi Ed,
The problem was that platform URIs were converting into relative URIs
like so:
<type
href=" ../../../../plugin/org.openiaml.model/model/datatypes.xsd#// foo "/>
Thus, if the runtime model instances were moved into a parent or child
directory, the URIs would have become invalid. Yes, it worked fine, but
if the model instance was moved to a different project or folder, I
think things would start falling apart.
Cheers
