Hello list,

now i can change class expression into my layers, but i can't see the 
resulting map modified. :(

I redirect the query to a php application through event manager as i saw in 
the documentation:
[...]
goEventManager.registerForEvent( 'ON_QUERY', 'my_query' );
[...]
function my_query () {
	var url = 'query.phtml?x=' + nX + '&y=' + nY + '&sid=' + 
document.forms[0].sid.value;
	frames['list'].location.href=url;
}

So the query action calls the "query.phtml" script that modifies the class 
expressions and ends with:
$_SESSION['gszCurrentState'] = $oMapSession->saveState();

But now, how  I can reload the map?
If I set the "highlightresults" proprierty to "false" in the query widget, map 
doesn't reload. Why?
Can I reload the map from my iframe?

Thanks in advance
