Or put a duplicate of the collection in the context with a different reference
name. During the loop, you can remove the item from the duplicate because you
aren't affecting the Iterator of the original. Then work with the modified
duplicate.

Hi Chris,
It seems to me that in java, Iterator can not be modified during the
iteration loop. It is not particular to Velocity though.
If you want to remove elements, maybe during the loop, you could mark the
indexes for the items to be removed, then, remove them afterwards?
Cheers,
Jian

All,
I'd like to mutate a collection during template evaluation --
essentially, I'd like to call Iterator.remove() during a loop. Is that
possible? Does Velocity expose an Iterator or anything like that to the
template?
Or, am I forced to iterate over one collection and add to another one?
For that matter, is there a convenient way of creating an empty
ArrayList or something similar?
Thanks,
-chris
