The alternative is to simply stick with the method of copying the
featuring to a list in memory.
Like Andrea said earlier, GetFeatureInfo isn't meant to get a long list
of Features. Usually even just one.
*Normally* there shouldn't be a problem. I guess I'll just give up on
trying to do it otherwise :/

One thing you can do (do you control the html template that is looping
over features?) You could add some logic to check if the iterator
implements FeatureIterator and if so close it at the end?

This works fine, but what is a pity is that in theory there is no
absolute guarantee that the iterator will be closed.
It is possible to do a break inside a collection loop in your
template, and not finishing with the last item. I don't see why you
would do that with features, and it is not done in any of the
existing template I think, but...
can we maybe include in the documentation that it is not advised to a
break when looping over the features in a HTML template?

Well one evil thing to do would be to scan through once and collect
the feature ids (perhaps you could do that efficiently?); and then
make a collection that produces an iterator that fetches the
matching feature for each feature id in turn?
Not the best idea; but something.
The problem with that would be performance again.
But I'm looking at something now that might work. Textmarker
actually has its own Iterator model, and what I am doing is
implementing that one, which wraps a FeatureIterator and
automatically closes after the last read. Something like this:
|public TemplateModel next() throws TemplateModelException {
if (!hasNext) {
return null;
}
Object o = iterator.next();
hasNext = iterator.hasNext();
if (!hasNext) {
iterator.close();
}
return new BeanModel(o, wrapper);
