[OpenLayers-Dev] allOverlays question

[bartvde at osgis.nl]

Hi list,

I am tracking down an issue in my application. I am using allOverlays true
on the Map object. When I start up my application, a layer with no scale
info set is as the lowest in the stack and hence acts as the "base" layer.

However, I have a control which raises this layer (a marker layer) to the
top, and then another (WMS) layer acts as the "base" layer. This layer is
however scale-dependent, which means the map is not zoomable anymore after
1:500.000.

Is there a way around this, or is this a side-effect of allOverlays? Do I
need to resort back to my dummy base layer?

Best regards,
Bart
