I am writing a data source plugin that connects some of our CORBA device
control objects as GIS features. Some of the devices have multiple
camera snapshot images. I was thinking of having a multi-attribute named
"snapshot_url" that would be repeated for each camera snapshot
available. I would them provide a custom FeatureInfo.slt that would
convert those attributes to <img> elements. I have it working for a
single element, but not multiple.
Gotcha. Well if you want to live on the bleeding edge, which will
definitely evolve in to the sustainable geotools core, then do check out
the complex features branch. It will be the main focus of the 2.3 release.
If you want a quicker solution that involves more hacking, then modify
MultiAttributeType.
What are the errors your getting when compiling with maven? And what
version of GeoTools are you using? If you're just hacking on multi
attribute type it probably makes the most sense to just download
2.2.RC1. Get the source code, and you should be able to build it with
maven.

Apologies, I don't think MultiAttributeType has ever really been used.
It was an experiment, but none of our parsers ever put things in to
it. Why exactly are you trying to create a MultiAttributeType directly?
If you're needing complex functionality, then you should check out the
complex features branch. I think this:
http://svn.geotools.org/geotools/branches/complex-features/ is the svn
link. This branch completes the experiments with a full feature
model, that works with datastores and complex schemas.

I am trying to use a MultiAttributeType. But when I create a feature
using an ArrayList for the attribuite, it complains that it wants a
java.util.List not an ArrayList. I think the problem is that in
ListTypeAttribute.java, it checks for:
if(obj instanceof List){
perhapse it should be
if(obj implements List){
I tried to make the change and compile the code, but after an hour of
trying, I could not get either maven 1 or 2 to compile the project
(it complained about problems in project.xml).
Any thoughts?
