Request to share your inputs in one of the OAF issue. I have created a standalone stack layout region and inside that i have created 3 fields along with submit button in the child region of this standalone region. when I run the standalone region in jdeveloper, ProcessRequest method is called without any issues but when i click on submit button, ProcessFormRequest is not called at all .Even debug messages inside the ProcessFormRequest ,so ProcessFormRequest is not all called even after clicking submit button.Am I missing anything here.Please share your thoughts on this
