[udig-devel] Mapserver WFS, PostGIS and uDig

[Jody Garnett]

Welcome! (comments are inline) I should of course ask what version of 
uDig you are using?

We do have a long history of oddities with the Mapserver (and indeed 
*all* WFS implementations) uDig follows the specification to the letter 
so it is very easy to configure MapServer incorrectly and confuse matters.

The raster stuff is *great* - but only on trunk :-) The underpinnings 
have been rewritten over the course of a couple of years for another 
project and uDig only just has started to benefit from it. I hope we can 
make something available for you to download over the next couple of 
months, right now it is only available in source code form.

That does seems strange - it sounds like the code to create a default 
style is choosing the wrong one. uDig does check the table information 
in order to figure out what kind of geometry is available, I will see if 
I can reproduce the problem here - if not I will have to ask you more 
questions.

Often their are configuration problems at all three :-)  Can I ask if 
your MapServer is working correctly as a WMS for uDig?
