"is not a valid value" error after a server event from interactive form to SAP Webdynpro Java




I am getting this strange error when ever there is a navigation from Adobe interactive form to Webdynpro Java.

And it happens only with one of the subform.

I have 3 subforms on my Adobe form, and I have the same Button events for all the three subforms. Whenever there is a navigation to webdynpro when this particular form is visible, the form gets reloded and I get this error "is not a valid value". But it is not going to the onActionSubmit() method because I have a messagemanager statements written in my code, but it is not printing those statements.

And this happens to only one subform.

This is my form structure


-> sfHeader

-> sfForm1

-> sfForm2

-> sfForm3

-> sfButton - this has all the buttons and is common for all the 3 subforms

I get the error when we have sfForm2 visible and there is a server event happening.

Can anyone help me out with this.

Thanks and Regards
