Append MultiUpload Before Submit


I have a transaction form which let user to key in inputs and they need click submit button to submit the transaction.Before submitting the transaction, they could  upload multiple documents as they wish.

My concern is that transaction id is created after submitting the transaction.How should i keep those uploaded document before the transaction is submitted.And tie the uploaded documents to the transaction id after submitting the transaction. 

Does anyone has idea how to do this?Help

Hi Johnson,

You can do something like the Multiple File Upload component ( does:

  • Have an Entity where you store the file.
  • That entity will have the file (Binary Data) and the session id as  attributes
  • When you save the transaction you update the Entity with the transaction Id for the records with the session Id.
