Hi Rasa Rockers,

please help me, are migrating the code from 1.x to 2.x. where i am facing a challenge to convert the form action into formvalidation. I have pasted my class code here ,

my code stops working on utter_dispacher, I have slots for this form and here i have some business logic for each slot, so going forward ,Will post my submit classes, if it is required. why uttr_dispacher is not working for “text” not sure. someone help me on it.
