JoinFieldValue Functionality
Following is the procedure whihc i implemented in field setup of contact.
In Contact Field Setup I have created new field with following properties.
Display Name :Test
Field Type : Text(Short)
Default Value: JoinFieldValue('<Account>',[<AccountId>],'<Location>')
PostDefault : Yes
I have added this new field to Contact Page layout and i can see it on UI.
Now when ever i am creating a new contact and assiging an account to that contact and saving it, This test field is populated with the Location of that Account which is associated with newly created contact.
It is fine till here. Now my issue when ever i edit a perticular contact and change the associated account with that contact, the above field should also change its location value to the location of new account, but this is not happening.
