[Zope] ZTUtils.Iterator value in ZPT

[David Pratt]

Hi Chris. Thanks for your reply.

My understanding (which may be flawed) is that ZTUtils iterator 
provides values of a sequence as you iterate over them with a repeat 
statement.  I believe what I am trying to do is sensible.  I have 
looked at the api and can't seem to get the right magic using the 
methods  provided.  Tabindex for forms keeps track of tab position so 
when you use tab key it moves the cursor to next field tabindex in form 
.  So if I have 5 input fields from top to bottom, I want to define an 
iterator object, and obtain the next number in the iterator when zpt 
does its thing to create the form so that I would have a tabindex 
starting at 1 and next field value would be 2, then 3 etc.

A range by itself doesn't do the trick since it provides all values to 
the variable where I am looking only for a single number incremented to 
the next value.

Regards,
David
