[Cartoweb-users] Show layers in a defined order

[Simon ORTET]

Hi Oliver

On line 478 I have : $this->orderedMsLayerIds[] = 
$this->selectedMsLayerIds[$id];
Cartoweb can't find the $id index in the selectedMsLayerIds collection.
I made a print_r of the selectedMsLayerIds collection and i miss a layer 
that i checked by javascript /chargeVue() /function. So i assumed that 
Cartoweb needs first a /CartoWeb.trigger('Layers.LayerShowHide');/ call 
to gather the layers checked in the tree and update its collection. And 
only then, i can make the CartoWeb.trigger('LayerReorder.Apply'); to 
reorder these layers.

The problem is that i want to do that in only 1 ajax call. I'd like to 
avoid writing a new plugin. What could you advise me?

Thanks for your help.
