I don’t want the whole data record. Just a few fields that you need. Maybe
make a class like this:
[Bindable]
Public class DataClass
{
public funciton DataClass(fee_chosen:int, fee1:int, fee2:int...)
{
this.fee_chosen = fee_chosen;
this.fee1 = fee1;
...
}
public var fee_chosen:int;
public var fee1:int;
...
}

Know an easy way to export my SQL data as something I can post here? Something
like an SQL to XML conversion, so I can include the data in a text file that
the test-program can read?

The data grid IS editable, and one of the columns has renderer-as-editor set.
NOT the column that's giving me the trouble. In fact all the columns have
editable set to false, except one column -- again, NOT the one that's giving me
trouble.

Not 100% certain what you mean here... Check to see if the selectedItem isn't
null? The problem I'm having is not that the selectedItem changes (or appears
to change) when you scroll. It's solely in the drop-down. The data that
appears in the drop-down will change from time-to-time as you scroll -- but the
selected value doesn't change ever, unless you change it manually. And when
you do change it manually, it shows the value it's supposed to show! Then you
re-open the drop-down and THAT show's the correct values, too! That's what's
so weird about this problem.

I've never used the commitProperties() function... What does it do? And when
does it get called? Would that work 100% of the time? Basically you're
telling me to do "super.data = value" in the "set data()" function, then
populate the drop-down and selectedItem stuff in the commitProperties()
function? Is that what you're saying?
I'll be working on writing a test-case -- the biggest part of it seems to be
exporting my data. I can't find a shortcut to doing that. But if you can
answer my above questions, then maybe I won't have to write the test-case?
Anyway, thanks a bunch!
