Hi all,

there is a problem when I have two projects with one or more layers that are present in both projects.
If I set different styles for this layers in QGIS Desktop and I see the two projects in QGis Server I have no difference styles for this layers.
It seems that the first project load in QGis Server is ruling.

I'm using QGIS 1.8

Best regards

Do the layers have the same layerID?
The layer id is meant to be globally unique. Otherwise, the QGIS server won't be able to cache layers and styles (and thus loose performance).

No problem if the layers have different id.

But in a classic workflow is possible that fot the preparation of a project we start with a template project.
So, in this case, the layers of the template project have the same id in all the derived projects.
If I change the associated style of one of this layers in a derived projects I don't have change in the WMS result.

Anyone had the same problem and know the way to resolve it?

A solution may be the association layer id / project at Qgis Server level?

All the best.

Agreed, a pretty annoying issue; having IDs as a combination of the project name and the layerid seems the way to go

Please test with a recent QGIS release (2.18 or 3), if the issue/request is still valid change the affected version accordingly, if is fixed/implemented then close the ticket. Thanks!
