[Users] UrlLegend

[florent.gravin at bluecham.net]

Hi,

i would like to use URL to set my layers legend, instead of WMSLegend. The
point is that i add my layers after the legendPanel is rendered (because
the user can choose to add some layers).

As i understood, i have to

1. add my layer to the Map (this triggers to add a record to the
GeoExt.mapPanel.layers and this trigger to add its legend to the
legendPanel as WMSLegend type)

2. get the new layer record (mapPanel.layers.getAt(idx))

3. set lengURL param to the record..

so when i specify i want an URL legend it's too late, it have already been
aded to the legendPanel as the wrong type..

so how could I specify that i want a url legend for my layers before all
geoext events have been triggerd

thks for help
