Acceleo M5's custom URIConverter at

	tempBundle = AcceleoCommonPlugin.getDefault().getContext().getBundle(
						Long.valueOf(segments[i]));

invokes a plugin that is not initialised when running standalone.

Comment 1 Ed Willink

Workaround:

a) diagnose problems by searching module for unresolved proxies

b) load the URIResourceMap with resolutions so that Acceleo doesn't get confused.

The BundleURLConverter is a class we use to resolve inter-plugin dependencies; it should never be used in standalone. This is a known oversight which will be fixed in the next milestone.
