I'm investingating why QWC is giving me problems with QGIS Server 2.4.
I've spot a difference between QGIS 2.2 and the master code which seems to cause problems during the GetProjectSettings response parsing.
In previous versions of QGIS Server addDrawingOrder worked for project layers  while for embedded layers we had addDrawingOrderEmbeddedGroup .
Now we have only addDrawingOrder which seems to work only for embedded projects.
The result is that, without emdedded layers, the <LayerDrawingOrder> element will always be empty.
This seems to cause some problems on the QWC side. In fact now QWC works only with GetCapabilities, while it worked both with GetCapabilities and GetProjectSettings before.
