[Cartoweb-users] layers.ini dropdown

[Oliver Christen]

well, this case was simply never handled.

the function getLayersMask that handle the children layers of a dropdown 
doesnt check if a layer is restricted or not before trying to set the active 
layer. (or in other words, the children layer list is not updated to take 
into account the change of accessibility level)

it would certainly be possible to modify the function a bit to handle that 
case. I cant say more without testing myself.

regards
Oliver

The restricted (just for logged users) layer RNP was previously selected. In 
case a public layer ist selected the error won't occur.
