It is possible to ask for a boolean from within a process via processUI.ask(String, Callback).
However, we needed a solution to ask for a input string (e. g. the TAN during a SEPA transaction), rather than a boolean. So i implemented the askForInput(String, Callback) method. Now it is possible to ask for booleans and strings.
This is exactly what i was looking for !
Juste tested the web part and it works like a charm !
Thanks for the contribution, and thanks for the testing.
I integrated with development branch.
I'm attaching a sample usage class with BankTransfer.java for documentation purposes - please notice the timeout implementation to avoid long locks
