Will posted the following yesterday in regards to one of my questions:
When you extend the NavTool widget you need to reference the Map object
So your array of layer names would be like this:
Hope that helps,

Subject: [Chameleon] oMapSession and MapQuery object
I am writing a custom widget, based on the 1.99 Query widget, which
displays results in a popup window. My intent is to exectue a point
query on a layer, but not use a popup window. I just want the query
I've got my new widget working. It extends the NavTool widget and I'm
trying to move the code from Query/QueryResults.phtml (this is the
source for the Query popup window into my custom widget.
But I seem to be having trouble with $oMapSession, used to create a
MapQuery object: $oMapQuery = new MapQuery($oMapSession);
In my widget I have:
include_once( CHAMELEON_PATH."/common/wrapper/map_query.php" );
The MapQuery->executePointQuery() is returning no results. I suspect
the $oMapSession because the $oMapSession->$oMap->nLayers is not set.
In my widget I can successfully use:
$oMap =& $this->moMapObject->oMap;
So perhaps my problem is how to access $oMapSession in a NavTool widget?
Very similiar code in the QueryResults.phtml works fine.
