Hi Mauricio,
WITHIN-POLYGON combination works with CQL and ECQL.
It's the WITHIN-ENVELOPE combo that doesn't work with ECQL. I just
reported the issue because WITHIN-ENVELOPE worked with CQL.
If I run ECQL.toFilter("WITHIN(the_geom, ENVELOPE(0, 1, 0, 1))").toString()
I get back
[ 1 within POLYGON ((0 1, 0 0, 1 0, 1 1, 0 1)) ]
One of the coordinates, "1" was used instead of the geometry attribute,
"the_geom" in the filter expression.
But just like what Andrea and Jody said, if it's not really your intention
to support the conversion of ENVELOPE to POLYGON, it might not be an issue
then.
Cheers,
