Christian E Gruber commented on TAPESTRY-1830:
----------------------------------------------

Hmm.  True, but Howard's suggestion still requires that something be coded into 
the page class. (ie, the loop component itself).  I'd like to see no 
requirement for that for purely "internal" local variables.

when you say "can access the component", are you meaning something like 
${component:<comp_id>:<variable>} ?

> allow local value and index parameters (i.e. not page class variables) in 
> loop, count ... components

> index and value parameter in loop (and all components like it) often used 
> just in page templates and there is no need to access or change them in page 
> class.
> sharing this parameters to use directly in page templates, may help 
> developers to write most cleaner page classes.
