Re: [udig-devel] Help wanted for testing

["andrea antonello" <andrea.antonello@xxxxxxxxx>]

- info tool on WMS with 3 layers loaded: cities, parks, elevation/bath

I click on a park:
- cities is empty as expected
- parks shows info, as expected
- elevation shows the following error:

Hi Jesse,
was answering Adrian, so a part of what you ask is there.

The summary of that all is:

What people expect to happen is that if they have a projection set for
a map, if they add layers without projection info, the layer is
interpreted as being in the projection of the map. No doubt about
that. Arcview does it like that and people expect it to be like that
:)

So the scenario is just one: if no prj information is there, the layer
(shp, tiff, whatever) should be interpreted as living in the prj of
the map. If the layer is the first, and the prj is not yet defined, it
is ok to go in the generic 2d space.
