1. I create Leads by calling REST API, it works fine.
2. Later I create an after_save logic_hook for Lead Module. In the code, i have only one line: $bean->retrieve($bean->id).
3. Now if i try to create leads by calling REST API, the email is not saved! Actually, the email information is totally lost!

My question is: my code is in after_save logic hook. Shouldn't the email address had been saved before running my logic hook code?

By the way, if i create a Lead within Sugarcrm, the email can be saved properly.
