Change queryable layers - Essentials

Hi all,

I want to change the queryable layers of my GVH application on the fly. I'm able to change "queryable" property of a layer ($site1.site.essentialsMap.mapServices[0].layers[0].queryable) from a VertiGIS Studio Workflow. These changes have effects before the QueryBuilder is first run. But it seems that once the module has been initialized, changing the queryable property does not have any effect anymore.

Is there another way to change these queryable layers on the fly? Or is there a way to re-initialize the QueryBuilder module?
