please provide more details.
I have run through the Create pages wizard and set a field to be encrypted using the HASH encryption type.
Afte the pages are created, i edit the Insert record behavior on the insert page and the column is properly bound to the form element using the HASH Encrypting type. I don't quite follow you explanation of the issue.
For adding the insert behavior, it looks like it is adding the wa_hashencryption.php require once line after the insert behavior code, i am logging a bug for this issue.
