Hi
I am sorry that Ihave not used UML with Acceleo so my advice is limited
however...
Provision of the UML registrations was always a pain and got worse after
the upgrade to UML 2.4 and then 2.5 support. A UMLResourcesUtil.init()
helper method was therefore provided. Any failure to use this method is
likely to encounter significant difficulties.
However Acceleo has unfortunately created unique challenges by trying to
fudge an equivalence between edit-time and run-time URIs and so what I
recommend may not be helpful. You need to check whether your style of
UML URI exposition is compatible with the fudge. When I was using
Acceleo for OCL, I needed to override some of the start up methods to
bypass the fudge.
[The "librairies" typo in:
uriMap.put(URI.createURI(SysmlResource.LIBRARIES_PATHMAP),
uri.appendSegment("librairies").appendSegment(""));
probably does not help. There should be a SysMLResourcesUtil.init() to
avoid such typos. Raise a Bugzilla.]
Regards
Ed Willink
