symbol levels ignored for rule based rendering

[mayeulk]

Using the new symbology with rule based rendering, symbol levels are ignored

Step to reproduce: have some roads with two layers for the symbols. Click on "Symbol levels". Check "Activate symbol levels". Define levels. Click OK, then apply. Symbol levels are not applied.

---

Related bug: Just after defining symbol levels and clicking apply: Click on "Symbol levels" again, levels defined are still there. Click OK; click OK again to close the layer property. Click on "Symbol levels". They are gone.

Same bug as on version 1.5.0 tested today on latest trunk version 1.6.0 r14309

This is addressed in patch #2832

Hi, this has never been solved and was closed by mistake (the following comment acknowledged that symbol levels are ignored for rule based rendering: ​http://trac.osgeo.org/qgis/ticket/2832#comment:7 )

And in fact, symbol levels are still ignored. As I wrote in the mailing list, for now, all NG renderers (Single symbol, categorized, graduated) have a working "Symbol level" button, except the rule-based renderer (which has a non-working) button ; the patch at #3222 will give similar behaviour on all renderers. For the moment we have a button that does nothing. jctull is correct here: ​http://trac.osgeo.org/qgis/ticket/2832#comment:11 : "We still don't get the symbol levels"
