I am developing one web dynpro application to display the records in MARA table.
I have created a radio button.Logic is if radio button is selected then displaying of the record should be done.
NODE_PARENT consists of NODE_CHILD ( which consists of fields to be displayed ) and key holder ( attribute which is used to check whether radio button selected or not ).
In radio button properties i used selected key as attribute of the node NODE_PARENT.
Now in supply function i am reading the parent element attributes i.e. radio button and checking if it is selected then read the data from MARA and bind it.
But i am getting the runtime error
" Context binding of property SELECTED_KEY cannot be resolved: Node MAIN.1.NODE_PARENT does not contain any elements "
what is the reason for this error.
Thanks in advance.
