In my component, I'm have a table for "Professors". The table stores all sorts of information about the professor, and in the case of a new record, creates a new Joomla user account. I have this all working just fine in the postSaveHook function with the fields generated from the XML.
To finished, I have to obtain the password for the Joomla user account, so I need an input field for the user to provide it, but the password is not to be stored in the table with the other Professor info, only used in the CreateUser function. The postSaveHook function only provides the data that was saved (and described in the related XML), so if I put such an input on the page, where is it available "in the flow of things" so that I can create the user account with the password that the user provided with the input field, but not have to save in in my table?
