Also consider using a ModelLocator to store this list of persons. Have a
look at Cairngorm - it helps.

i think i am going to take your suggestion and use the person
instances themselves as the dataprovider for the combobox, thanks for
setting me straight!

If you really need to find a Person instance based on its ID, that
would depend on how and where you stored the Person instances. In
an Array? In an Object with the IDs as the keys and the instance
references as the values?
But it sounds like it would be easier if each item in the
dataProvider for your ComboBox was a Person instance.
Then comboBox.selectedItem would give you the selected Person
instance. You'd simply specify labelField="Name" to make the
ComboBox display the names.

*Subject:* [flexcoders] get class instance by property
hi,
i think i have painted myself into a procedural corner, i have
numerous instances of a class 'Person' in my application. Now i
have a combobox with the ID and Name of all these 'People'. When
I select a name in the combobox, i want to run a function on that
instance of the Person that ID belongs to- but have no idea how to
get that instance when all i have is the ID to get it by.
How do you reference a class instance by one of it's properties?
