When a rule based renderer is used, it is not possible to activate symbol layers.

Hi Anita, I'm running master here, and using Rulebased Renderer in a python plugin.

But I can add rules, and for every rule I can open the style and then add other symbol layers...

(trying with polygons here...)

What do you mean with 'not possible to activate'?

Sorry, I meant symbol levels not layers.

There are related tickets #13282 #13099 #12892 with quite discussions. There were some more discussions on the dev mailing list.

I am somehow reluctant to enable usage of symbol levels for rule-based renderer because this would limit us to one rule per feature. For qgis 1.7.0 it was decided to apply a patch that allows symbol levels for rule-based renderer. But for longer term (qgis 2.0) I would like to see a different approach of defining rules similar to SLD.

If it's a conscious decision to not allow symbol levels in rule based renderer, I think the button should be greyed out. Otherwise users start to wonder why it simply does not work.

I'll close this as duplicate of #13099
