Hi Chris

I guess something like that but that is what an iterator does.  ZTUtils 
just doesn't provide a method to get the values out of it (which it 
could if the methods were available).

Well, by hand is not the solution either.  It is not as simple as that 
since I am using portlets in CMF and there are forms in portlets too.  
You can't just number them like 1,2,3 etc because you end up with 
conflicts in tabindex values when your templates are rendered.  This is 
the second problem I am trying to solve because ZTUtils allow you to 
pass into it whatever sequence you want.  You could give it a different 
sequence to start with so when it iterates using its own sequence, 
results keeps the tabindex from conflicting.  This is more of a case of 
looking at an existing tool to perform this so you can retrieve from 
your ZPT (that doesn't require you to write one with all the security 
bypasses to make it work).  It appears ZTUtils is the tool that could 
do this.  I mean it is an object, it iterates, it iterates on values 
you pass it , it knows its current state and the security has been 
bypassed to let you call it in a ZPT, it just doesn't provide a method 
to obtain its values directly.
