I have an inline item renderer, bounded to a data source, which is
an array collection of objects. These objects are used to
dynamically display controls in a datagrid. Everything seems to work
fine for awhile. I can slide the slider down and up and down, but
when I try to slide it back up the second time I get the following
error:
RangeError: Error #2006: The supplied index is out of bounds.

In my item renderer, I first removeAllChildren(), and I think this
is what is causing this error. I just can't figure out why it only
does it after I slide the slider up for the second time. I have been
working on this for weeks now it has taken an unbelievable amount
of time and I still can't figure it out.
Any help is VERY MUCH APPRICIATED!!!
Thanks
