[S2] JSP/OGNL - displaying iterator length

[yitzle <yi...@users.sourceforge.net>]

I got an iterator that works fine and does what I want it to:

<s:iterator value="iterator">
...
</s:iterator>

A few lines above, I try to print the iterator size:
Total: <s:property value="appRegistries.length"/>

Doesn't display anything.

The OGNL Guide says it supports .length for arrays.
Does is not support iterators? Especially since the iterator is simple
an array container?

The iterator class doesn't have a length property:

http://java.sun.com/j2se/1.5.0/docs/api/java/util/Iterator.html

you are going to have to get the size from the collection itself.
