I am able to create a button dynamically and attached the action
Below is the code.
data:root type ref to cl_wd_uielement_container,
bt type ref to cl_wd_button.
root ?= view->get_element('ROOTUIELEMENTCONTAINER').
bt = cl_wd_button=>new_button( text = 'Submit' on_action = `SAY_HELLO` ).
cl_wd_flow_data=>new_flow_data( element = bt ).
root->add_child( bt ).
In the method 'SAY_HELLO' I have written code to show one message. But it gives dump and does not allow me to create onactionsay_hello method even.
I have created SAY_HELLO as method type 1(i.e event handler method).
My expectation is :
One button should be created dynamically and after clicking it should prompt some message . and everything should happen dynamically.
