Just like the insert page, RAD has created inputText components for each selected field in the database table and
bound the fields to the RR data components. RAD has also created two buttons that will invoke the update and delete
functions in the pagecode class (i.e., UpdateEmp.java). If you look at the UpdateEmp.xhtml source code, you'll see
that the EL statement for each button's action parameter invokes a particular method in the bean/pagecode class
(pc_UpdateEmp). For example, the Submit button invokes the doEmpRRUpdateUpdateAction method. Where did that
method come from? RAD automatically generated these methods when the Updating option was selected in step 3.
Although RAD has done a wonderful job, the default text for the Submit button should be changed. Submit does
not really describe what clicking the button will do, so we will change the text to Update.
