[CDO] Custom query handlers on arbitrary container? [message #1063736]

It seems that custom query handlers have be registered on IPluginContainer.INSTANCE, if using a different container
server's ContainerQueryHandlerProvider.getQueryHandler does not seem to be able to find them:

Is this by design or should one be able to register custom query handlers for an arbitrary container?

If you're using a container different from IPluginContainer.INSTANCE you need to inject a respective
IQueryHandlerProvider into the repository, e.g.:

IManagedContainer myContainer = ...;
InternalRepository repository = ...;
repository.setQueryHandlerProvider(new ContainerQueryHandlerProvider(myContainer));
