[mapguide-internals] FW: [mapguide-users] Ajax viewer zoom tool

[Jason Birch]

Hmm...

That's unexpected; I wouldn't have expected BaseMapLayerGroup to have a
minOccurs="0".  Does this mean that the BaseMapDefinition and its
associated FiniteDisplayScale were intended to constrain the scales of a
map when there are no base map groups defined?  If so, wouldn't it make
more sense to have the finite scales as a child of the MapDefinition?
My first though was that this is just an oversight in the AJAX viewer...

Is this something that will work with Fusion (I kind-of doubt it, but
could be surprised)

YES!

Well done Kenneth. That's the one. The only thing I thought would be an
issue was that I took out the <BaseMapLayerGroup> and <BaseMapLayer>
from your XML and left in the scales. It now works very smoothly without
that juddery redraw of base layers. I'm able to see the scales in Studio
now even though there are no base layers. Why can't you do that anyway?
Excellent work - you win the cold christmas turkey!
