[Chameleon] Can LegendTemplate keep legend-unvisible layers map-visible after update?

[Paul Spencer]

yes it is possible, but you have to trick the widget a bit to make it 
work.  Try adding the following:

[if name=layer_group oper=neq value="Bestemmingen"]
[if name=layer_status oper=eq value=1]
<input type="hidden" name="legendlayername[]" value="[leg_layer_name]"]
[/if]
[if name=layer_status oper=eq value=2]
<input type="hidden" name="legendlayername[]" value="[leg_layer_name]"]
[/if]
[/if]

The way php processes GET/POST will ensure that the layer names for 
other layers that are "ON" will be included in the array legendlayernames.

Cheers

When starting the application I want the user to be able to turn on the layers contained in the 'Bestemmingen'-group. So only the layers in from this group are shown with a checkbox in the legend. Therefore a use following code in my legend_template.html:

> Turn on the layers from the 'Bestemmingen'-group works fine this way, but the problem is after the update of the map the other to groups of layer which by default have status=ON are turned off. Is it possible to keep their status ON all the time?
