• Do the self registration by sending a key to the registered email address. Only by using that key the account can be activated. This way at least on ensures a proper email address initially. There are however ways to temporaryly generate email accounts, which kind of bypasses this system. Furthermore, if an email address becomes invalid because the domain is switched off, this does not help.
  
• Email at least an error notification to the admin in case of failure.

Just answer it myself : I thought of the checkboxes in front of the attributes as boolean. However, it has to to with the browse feature filtered browsing =1= In this way you can, when checking one of the checkboxes, browse to the same item clicking the next and previous button. Sorry , my question was about RTFM ( Read The Fucking Manual ) So this question is solved.

However , it would be nice to have a checkbox in front of one attribute. Suppose you have a lot a entries in a record ,that are readonly( predefined). The user of the form must only confirm that a job is done by checking the checkbox without going to the edit mode. So, the checkbox is writable in readonly mode. I can inmagine something like : attribute record check = attribute in the configuration file. In this way the user of the form says : job done. There can be only one checkbox for the record.

[ job done]  [ customer ] [ activity ] [ What should be done ]
[X]           BLA          Check job1   Backup mail check
[]            BLA1         Check job2   check error report
[X]           Bla2         Check job3   check MQ jobs
