Hello Guys,
I created an issue for this problem a while ago :
https://jira.codehaus.org/browse/GEOT-3137 and attached a patch that solve
this problem. I guess the main reason why its still open is, that a few API
changes were required and I didn't requested on the geotools mailing list
for voting again..
Do you agree with me, that this feature should be in the core? Than should
we renew the request and let the PMC members vote on this...
Cheers, Frank
