may be related to #22.

Did you update your HEADS IDE? See README in tutorial 3 for the update procedure. Tell me if it improves the situation or still crashes.

[skorsky]

The stack trace shows that I'm using org.sintef.thingml.resource.thingml.ui_0.6.0.201502122331, which is the latest according to http://thingml.org/dist/update/.

[brice-morin]

I tried to clean some of our plugin.xml, which might solve that particular issue. It might be some other exceptions poping up, but nothing blocking. We'll fix the non-blocking Eclipse-related issues later on.
You can try to update your HEADS IDE in a few minutes.

[skorsky]

The menu entry Run as --> thingml Application is gone from the context menu of a thingml file. Thus, exception is not reproducible.

[brice-morin]

AFAIK, this menu was deprecated. One should use the HEADS/ThingML menus available by right-clicking on the thingml files, as explained in the README of tutorial 1.

@ffleurey can you confirm that?

[brice-morin]

I checked with Franck and that menu was deprecated anyway. I consider this issue solved then. We might later on re-introduce a proper Run as --> ThingML where you could choose which compiler, etc you want to use, but it is not on top of the list right now, since the other ThingML menus can achieve that already.
