Hi all!

I'm working with MapScript Java Interface. I need make query's in a user =
selected layer. So, when the user select a layer, I call =
layer.setTemplate("any.html"). When the user select another layer, I =
call layer.setTemplate("") in the previously selected layer. This don`t =
work, and mapObj.drawQuery() method hilite elements in the two layers =
(the first selected and the second). I need hilite only the second layer =
in the last case.
I try this: layer.setTemplate(null): produce a segmentation fault =
outside de Java Virtual Machine.

Thanks in advance, and sorry my english.
