[Geoprisma-dev] mapfishlayertree and initialview

[Alexandre Dube]

Yves,

  The behavior you're describing doesn't apply to the Shortcut widget, 
see the example [1].  The MapFish layertree already listen to the 
"visibilitychanged" and "changelayer" events (see 
MapFishLayerTree.xslt).  I don't know what's going on, but maybe a look 
at the source of the layertree and shortcut widgets could help.

  Regards,

Alexandre
