Hi
I have a store created and it loads the JSON Data which is in the form
show below. Now I am trying to get the list Controller to use the store
and display the ACCTNO+" "+ID1 for example "0001 Transfreight" in the list.
I obviously need to bind the store to the controller but I am not sure
how to do this given that the list controller is expecting an array. Any
clarification would be appreciated.
Thanks,
Simon
