I am having trouble forming a properly formatted CQL request using geoServer cross layer filer functions and was hoping others could assist. My request is as follows:
http://localhost:8080/geoserver/wfs...cts','the_geom','CODE=A1')))&version=1.1.0The intent is to select the towns that are within a selected District shape.
With the above request a null data set is returned:
I think the formatting of my query string 'CODE=A1' is wrong, so geoServer returns a null set for the queryCollection, meaning the intersection is being performed against a null set. (Note: CODE='A1' works fine if I query Districts directly.)
I have also tried 'CODE='A1'' and some other variations but this nesting always causes an exception similar to the following:
Could not parse CQL filter list. Encountered "A1" at line 1, column 92. Was expecting one of: ")" ... "," ... "/" ... "*" ... "+" ... "-" ... Parsing : INTERSECTS(the_geom,collectGeometries(queryCollection('AU
istricts','the_geom','CODE='A1''))).I have looked at lots of examples but cannot find one with a filter string in the queryCollection function.
Any help would be greatly appreciated.
Thanks, Nigel
