[Qgis-developer] [2.6] QGIS-server: failed to show one layer rules-based styling

[Yves Jacolin]

Hello,

I am testing QGIS server 2.6 for one of my QGIS project with a lot of layer. 
We are requesting layer via WMS service. There is, however, one layer not 
working properly (well not at all). This layer has 9 rules for styling which 
seems create the problem.

If I use a single class or graduated/continue classes, I can see my layer. The 
rules have this scheme:
* group 1 (one filter and no style)
  - class 1 : filter + style
  - class 2 : filter + style
  - class 3 : filter + style
* group 2 (one filter and no style)
  - class 1 : filter + style
  - class 2 : filter + style
  - class 3 : filter + style

Does rules-based styling could be a problem for QGIS-server?

Thanks,

Y.
