| [QVTo] UnitResolverFactory weiredness [message #856161] |

Hello,
when using QVTo transformations programmatically, the method
InternalTransformationExecutor.doLoad() executes this code:
UnitProxy unit = UnitResolverFactory.Registry.INSTANCE.getUnit(fURI);
if (unit == null) {
/* ... cause error and return */
}
So obviously a UnitResolverFactory must be there which handles the input
URI (specifying the *.qvto script). However, the default
UnitResolverFactory which is present is the EclipseUnitResolverFactory,
does not accept my URI.
What I did now is I wrote my own
public class MyUnitResolverFactory implements UnitResolverFactory...
and registered it at the org.eclipse.m2m.qvt.oml.unitResolverFactory
extension point. However, while that works, I'm extending a private
interface so it's a bit shady.
What is the recommended way for this to "just work", be it in a runtime
workbench or not? The same question was asked here, but was never
answered: http://www.eclipse.org/forums/index.php/t/238973/
Thanks
Marius

Hi
You haven't provided your URI so it is difficult to tell whether
your URI is bad
the QVTo code is bad
the QVTo interface should be public

Well it's a normal platform URI, generated by
URI.createPlatformPluginURI(). It looks like this:
platform:/plugin/my.plugin.com/adir/transform.qvto
Again: if I simply squeeze in a custom UnitFactoryResolver that looks
exactly like the UnitResolverFactory.BasicRegistry it works. My only
problem is that this registry is not registered when running the debug
workbench, and that I have to hack it into it using the
org.eclipse.m2m.qvt.oml.unitResolverFactory EP.

Marius
