[OpenLayers-Users] [Geoserver-users] Filter Encoding

[bartvde at osgis.nl]

Your code can never work, OpenLayers.Util.getParameters() returns an Object
not a string.

Write you poligona.params.Filter to the Firebug console
(console.log(poligona.params.Filter)) and check if it is really correct.

Also you have a ; before the + for string concatenation which cannot work
as well.

+'<Literal>'+OpenLayers.Util.getParameters();+'</Literal>'+

Best regards,
Bart
