Re: [mdt-sphinx.dev] Issue
Hi,

from Sphinx side this NPE should be avoid. For this can you please open a bug in the bugzilla (https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Sphinx).

From your side, I think you need to initialize properly the environment (registry...) in a standalone mode for getting contributed extension points.

Dear All,

I would like to report an issue on sphinx :

Issue :

use case : Load a model with ARTOP 4.4.0 in standalone mode.

Sphinx Versions : 0.8.1, 0.9.0 M4 and M5
Hardware : Win 7 / 64
Observed Behaviour:
NullPointerException. See below for stack trace.

By "standalone mode" I mean Java with no OSGi and no Eclipse headless/workbench/workspace.

It's desirable to support standalone mode because its is significantly lower compared to launching OSGi/EclipseHeadless. This is valuable for JUnit tests and console applications, such as transformers, generators and compilers.
