I am using in the submission of the form, the option to "send pdf with
email", and when submitting the form, the exception was thrown.when i
receive the email, there will be pdf attached if its a successful
submission.maybe that's why the PAexecute82 error occurs. Could there be
some timeout issue going on? cos after i restart the aem server, it will
work again. But it could be i put my computer to sleep and didn't
shutdown the aem server before putting it to sleep.
