[OpenLayers-Users] Question on having multiple layers

[bradleyspencer]

Ali,

I have done this is what I would call clumsy javascript.

Have a look at the demo at http://ozdemo.getmyip.com/interopDemo.html

To do a getFeatuerInfo (GFI) the user needs to make a layer 'active' and
then I disable all mouse events and register a new doubleclick event for the
GFI request.

The problem I have not solved yet is that once I disable all mouse events I
lose things like doubleclick zoom-recenter and I am unable to reactivate
them after the user makes a subsequent layer active that does not have GFI
capability (i). Maybe you can help me?

Cheers,

Brad....

some what. This much I knew already but I was hoping to grab the layer
visible as well so I knew which layer to query data for.
