[Cartoweb-users] Make Outline plugin draw a ms_shape_obj

[Simon ORTET]

Finally I found why the layer was being activated.
When i do the
    $styledShape->shape = 
$pluginManager->mapquery->queryByIdSelection($mySelection);
in the handlePreDrawing function of my plugin, the 
queryLayerByAttributes function of mapQuery plugin do a
        // Layer has to be activated for query.
        $msLayer->set('status', MS_ON);

I added a
        $msLayer->set('status', MS_OFF);
at the end of the function and it's ok.

Do you think that could be a problem for the query plugin?
