So I have an object that is a detail to an account. However, on the visualforce page I'd like to select a field off of the account to associate the account instead of the account name
Example: Account: Name, Acronym. Relationship between the custom object and the account is on the account name.
Entry Page: I want to display the acronym instead of the account name after selecting from the lookup.
I have my own custom controller if that helps.
As a frame of reference in C# forms you'd have a dropdown with 2 columns and the first column would be the relationship and the second would be the display field and you'd hide the first column. Similar concept here.
