Thanks for the reply. I didn't see your reply until today (April 4). Last night, I made a few functional changes (unrelated, I thought), and one of them seems to have solved the problem.
There were a couple work fields stored in the form bean (ActionForm), called
userAction and systemAction, that were being used to determine which
buttons to display based on what the user was trying to do. I removed
the field called systemAction..... And when I ran the next test, the
system did a doPost but did not follow that with a doGet. How this could have solved the problem, I can't even begin to imagine....
When I get home from work tonight, I'll check the code rendered by the validator framework, as you suggested. I am using html:submit for my buttons; perhaps changing them to html:buttons would also have solved the problem (and a better solution as well).
Thanks for your help.
