Re: How to check if an iterator is empty inside a s:subset?

[Cristian Peraferrer]

Finally I've found that:

<s:if test="#attr.myListIterator.hasNext">

did the trick. The thing is that I wasn't able to figure out where to
find out "var" defined objects. Now I know that are accessed trough
#attr.

I hope it will help those people with a similar problem.
