[Geoserver-devel] GWC issue with layer group in version 2.6

Romulo_Vieira_da_Sil · March 2, 2015, 5:54pm

Hello everybody, I have a question about the GWC with layer group.
I could’t use the GWC with layergroup. I debug the code and found the following in org.geoserver.gwc.GWC in the method verifyAccessLayer:
LayerInfo layerInfo = getLayerInfoByName (layerName); //catalog.getLayerByName(layerName);
if (layerInfo == null) {
throw new ServiceException (“Could not find layer” + layerName, “LayerNotDefined”);
}

Is at this point that the error occurs, maybe because it is not searching in layergroup. I try this and worked:
LayerInfo layerInfo = getLayerInfoByName(layerName); // catalog.getLayerByName(layerName);
LayerGroupInfo layerGroupInfo = getLayerGroupByName(layerName);
if (layerInfo == null && layerGroupInfo == null) {
throw new ServiceException("Could not find layer " + layerName, “LayerNotDefined”);
}

I looked for something in the bug list, but I not found, so I suspect that I have done something wrong.
Any suggestions?

Thanks.

Is this layer group in a workspace? If so, that’s a known issue that is fixed in 2.7. The fix is not backportable but there is a work around. Add a Parameter Filter to the layer named WORKSPACE and make the default value the name of the workspace.

Thanks for your support. I forgot to tell that the layer group is in workspace.
I not understand right. In Parameter Filters don’t have a WORKSPACE for me, but i wrote in the text box and set the default value the same name of the workspace, but doesn’t worked.

Links to show how i did:

in this step, i wrote directly in the text box the velue WORKSPACE an selected List of Strings
