[Chameleon] LocateByAttribute and zoom to result

[Danilo Furtado]

Hi list,
I'm new in chameleon and mapserver and i trying to use the 
LocateByAttribute widget to search attributes in the shapefiles and then 
offers a zoom to option results.
Everything is wheel except the zoom to the extents of a selected 
feature, that don´t work.
The data Spatial Reference Systems is EPSG:27492

        <!-- Locate attribute -->
        <cwc2 type="LocateByAttribute"
            searchall="true"
            zoombuffer="50"
            height="90"
            width="400"
            highlight="true"
            allowdownload="true"
            popup="false"
            VISIBLE="TRUE"/>

Any help/direction would be appreciated.

Tanks and best regards
Danilo
