Datagrid Combobox itemEditor dynamically created in AS

-

i'm trying create inline cell editor datagrid dynamically created metadata api call. depending on data type, i'm specifying itemeditors on columns. i've been able fine on other data types need, except comboboxes, have custom attributes specific each column (the picklist values). these values loaded via api call.

my question is, since datatype of datagridcolum.itemeditor classfactory, meaning can't pass in instance of combobox (which makes sence since grid reuses editors) how can dynamically specify, using actionscript code, possible values of combobox are?

any suggestions appreciated. examples found in mxml , statically populated. thanks!

wow, after 2 days of messing this, took hour after posting figure out these 3 lines...
