Hello Experts,
I have following piece of code from main mxml and below that I have
component code for Combobox. Please let me know what is wrong in my
code. It wipe the value once I select values from combo box. I am
using label function to decode values as Yes/No when populating Data
Grid from the database. Also I will appreciate if I get a standard way
to display Yes/No list to display and store values(Y/N) in database.
My code is based on various examples given on this topic. Sorry if I
have made the Code-cocktail.
Thanks a lot.
Arshad
