[Cartoweb-users] layer dependings

[Oliver Christen]

well, it seems the "hidden" stat is conflictual with aggregate usage

since the layer activation/deactivation is handled via javascipt, I suppose 
you can try to modify the AjaxPlugins.Layers.Actions.LayerShowHide function 
in Layers.ajax.js
to check/uncheck the "hidden" layer when checking/unchecking the visible 
layer, just before calling the buildPostRequest.

its a bit hacky, but it should work

Oliver

that's the problem...
As I wrote, I tried make layergroup with aggregate parameter, but it
runs incorrectly.

Activate/deactivate of 2 children layers works good until use:
mapInfo.initialMapStates.default.layers.swdemo_budovy.hidden = true
Then are children layers displayed in legend but not in map.

I use:
layers.budovy.className = LayerGroup
layers.budovy.label = Budovy
layers.budovy.children = swdemo_budovy, swdemo_budovy_doplnok
layers.budovy.aggregate = true

Names of children layers in legend comes from mapfile.map, I don't know why.
For example:
LAYER
  NAME swdemo_budovy
  TYPE POLYGON
  STATUS ON
  CONNECTIONTYPE postgis
    CONNECTION 'user=fero password=h dbname=gis host=localhost port=5432'
    DATA "the_geom from swdemo_budovy"
  CLASS
  #  NAME "Swdemo_budovy"
    # TEMPLATE
    COLOR 235 200 120
    OUTLINECOLOR 182 130 17
  END
END

In legend is displayed name: "Swdemo_budovy"

I have to comment line "NAME" in CLASS bacause
mapInfo.initialMapStates.default.layers.swdemo_budovy.hidden = true
doesn't work properly when is not commented.

Why it takes the names of children layers from mapfile.map?
Is it correct?

I'm little bit confused...
