But then you have two different attributes, in my case I had a third-party
shapefile with one attribute for the image url. An other workaround : use
some split/concat functions to achieve the same result you got with two
different feature attributes.
Nevertheless, I guess a vote doesn't help a lot. The best way to get it
resolved would be bringing it back to agenda on the geotools mailing list.
You can find the discussion right here
