Description

Hi,

With a map with grouped layers, when the parent group is off and the user changes the layer status of any of the sub-layers there is a map refresh.

Because the parent group is off the map image will not change but a request is sent to the server adding load and implied performance issues (user sees the "Night-Rider" loading animation).

Should a map load be suppressed with layer edits when parent group is off?

This is currently not possible because the map image request has to be made to make layer/group state changes as well as getting back an image.

Ideally there should be a separate operation for fiddling with layer/group states, or the GETDYNAMICOVERLAYIMAGE operation needs a do-not-render flag, so you can fiddle layer/groups visibility without needing a rendered result.
