Hello there
we also have had some problems upgrading a geoserver instance from 2.2 to 2.7
we copied the data dir from one to the other and everything worked except for the cached layers… they gave the error below: Current styles of layer not available
we saw that manually going to the layer in the web admin and clicking save fixed it.. and then looking in the (gwc) layer file in the config we see that a new section has been added:
<parameterFilters>
<styleParameterFilter>
<key>STYLES</key>
<defaultValue></defaultValue>
<availableStyles class="sorted-set"/>
<defaultStyle>raster</defaultStyle>
</styleParameterFilter>
</parameterFilters>
we then wrote a little python script to GET the layer xml to a file, then POST the same XML back, which appears to have simulated cliking save on each layer and it is mostly working now.. except for a different GWC bug which I will now write a different email for.
so get the list of layers using:
curl -u admin:xxxx "http:// localhost:8080/geoserver/gwc/rest/layers/"
# write XM to a file
curl -u admin: xxxx "http://localhost:8080/geoserver/gwc/rest/layers/workspace:layer.xml" > xml.xml
# post xml back to simulate save
curl -u admin: xxxx -XPOST -H "Content-type: text/xml" -d @xml.xml "http://localhost:8080/geoserver/gwc/rest/layers/workspace:layer.xml "
maybe this helps someone

Sorry about taking so long to respond. I'd hoped to find some time to look into it in a bit of depth but I've been rather busy. I can't think of anything in particular that would cause this beyond, as Andrea said, the setLayer method not being called or the state of the filter being cleared after having been set. Figuring out why that's happening (or not happening) would require replicating it and doing some debugging.

Hi,
after upgrade to GeoServer 2.7.0 (running under Tomcat
6.0.41-2+squeeze6, Oracle Java 1.7.0.76, Linux Debian 64bit) I have
problems with a layer that used to work with 2.6.2.
The layer is accessed using the global /gwc/service/gmaps Service.
Example:
http://<server>/geoserver/gwc/service/gmaps?layers=naturpark:v_np_border&zoom=9&x=267&y=178&format=image/png8
Shortly after a restart of Tomcat everything is working as expected.
After some time (30min) a status 400-Page (text/html) is returned:
GeoWebCache
400: Current styles of layer not available.
The error persists until the next server restart.
This is what is in the log for a failed request (DEBUG Logging):
2015-03-26 14:40:21,917 DEBUG [ows.OWSHandlerMapping] - Matching patterns for request [/gwc/service/gmaps] are [/gwc/service/**]
2015-03-26 14:40:21,917 DEBUG [ows.OWSHandlerMapping] - URI Template variables for request [/gwc/service/gmaps] are {}
2015-03-26 14:40:21,918 DEBUG [ows.OWSHandlerMapping] - Mapping [/gwc/service/gmaps] to HandlerExecutionChain with handler [org.geoserver.ows.Dispatcher@anonymised.com] and 1 interceptor
2015-03-26 14:40:21,928 ERROR [geowebcache.GeoWebCacheDispatcher] - Current styles of layer not available. http://<server>/geoserver/gwc/service/gmaps
2015-03-26 14:40:21,928 DEBUG [geowebcache.GeoWebCacheDispatcher] - Current styles of layer not available.
This is actually an exception throw by the StyleParameterFilter class, it seems the setLayer method
never got called... but I don't know why. Kevin, do you have any clue?
Cheers
Andrea
