listener desired on "For" component

Hi there --

I have a situation where I am displaying (using a For component) a list of
editable items. When the form is submitted I would like to have a listener
defined by the component containing the For component called for each iteration
through  For's body after all the components within that loop iteration have
been rewound. 

There doesn't to be any to do this gracefully. I am settling on making one
compound component as the body for the For component. This compound component
has the listener method, which is being called manually within the component's
cleanupAfterRender(cycle). It seems like there should be a better way and I was
wondering if anyone had any suggestions? 

Should I modify the For component so that a listener method could be defined?

Thanks for any ideas.

What I would like:

<span jwcid="definesListenerA">
    <span jwcid="@For" afterIterationListener="listener:processItem">
        <span jwcid="thisThing"/>
        <span jwcid="thatThing"/>
        <span jwcid="oneMoreThing"/>
    </span>
</span>

Thanks ... I didn't think to look for another component. It doeslook like
InvokeListener is the correct thing to use.

Try putting an @InvokeListener component in your @For loop.

Subject: listener desired on "For" component 

Hi there --

I have a situation where I am displaying (using a For component) a list of
editable items. When the form is submitted I would like to have a listener
defined by the component containing the For component called for each
iteration
through  For's body after all the components within that loop iteration have
been rewound. 

There doesn't to be any to do this gracefully. I am settling on making one
compound component as the body for the For component. This compound

Should I modify the For component so that a listener method could be
defined?

Thanks for any ideas.
