That's actually what I had been doing previously by creating an attribute Expression off a field in the DBF and using a bunch of filter.or(exp) to point at the attribute. However I thought it might make more sense to use the FIDs since they are unique and it de-clutters the DBF a bit.
One last question: In the case of a shape file "service" is the FID always the form "fileNameNoExt.ID"?

Cc: [email protected] Subject: Re: [Geotools-gt2-users] FIDs and file name changes There is good alternative to StyledMapPane now on geotools trunk :-) I am afraid the FIDs more represent a selection on a single service (in this case a file) rather than something abstract. If you had an ID attribute in your file you could use that for a stable filter regardless of data source.
