I've used repeaters before so I definitely know how they work as a whole. I've
never had
the issue I'm about to describe and I've been fruitless in my search efforts.
I have built a custom-component (sort-of a menu) that uses a repeater to list
out the
menu items. In the mxml I've set its dataProvider to (hypothetically)
this.parentDocument.myArray (also tried parentApplication out of desperation
which didn't
help at all). When i place items into that array I can do
myComponent.myRepeater.executeBindings and the new items show up just fine.
The problem comes when I want to completely clear the list, remove an element
of it, or
set the list to something else (myArray = myOtherArray). Whenever I do any of
these and
then attempt to execute bindings, i get a huge error message...which follows:
TypeError: Error #2007: Parameter name must be non-null.

For clarity, ALL I'm doing is running executeBindings() and this happens. I've
verified over
and over that the data in my dataProvider array is clean and correct.
The only difference between this repeater and ones I've done in the past is
that this
repeater is part of a custom component instead of part of my main mxml program.
I can't
imagine why this would be creating any issues, but whether or not it's related
to that, I'd
be VERY appreciative of any help that you all could give. I've been working on
this on and
off for four days now and I can't seem to get anywhere with it.
Thanks, RV
