there are an alternative for múltiple load file in Bonita Community ?

No, you would have to write your own,

here is one possible design...

Pool data ListOfFiles is type DocumentList ListOfFilesTable of type list LoopingAdd of type Boolean

Step 1 Form has a file widget and an empty table (pointing to ListOfFilesTable) with TWO submit buttons (1) add to list of documents, (2) Submit.

On button (1) add an action that takes the file widget data (DocumentValue) and stores it in ListOfFiles, and save the name to the the ListOfFilesTable. NULL the file widget.

Add another action to set LoopingAdd to true

On button (2) Add an action to set LoopingAdd to false

Gateway1 is rather simple...if LoopingAdd == True, Loop back to the beginning of Step 1

if LoopingAdd == False, then continue on to next step...

So all your document data is now in a DocumentList...

Sort of tested as a proof of concept but not used in earnest yet.

Hope this helps,
