[TYPO3-dev] looking for a hook to use before rendering a backend page

[Ivano Luberti]

Hello all, I'm currently modifyng itypoexpiringfegroups to tightly 
integrate it with the TYPO3 group management so that the usergroup field 
reflects the content of itypoexpiringfegroups field. I'm planning to 
make the changes available if the actual maintainer agrees with my changes.

I have already been able to hook the process during frontend user logon 
and even to hack current extension javascript to modify values of 
usergroup field in the backend form when itypoexpiringfegroups is edited.

The last thing I want to achieve is that when the form to edit a user is 
called, before showing the values, I can hook the process to possibly 
modify the value of usergroup field taking into account expiration or 
starting validity of groups contained in itypoexpiringfegroups field.

I have already found

$TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_tceforms.php']['getSingleFieldClass']

but even if I can change value in the DB before showing them, I cannot 
update the $row['usergroup'] value. So backend user would see 
potentially expired values and save them back erroneously.

Does someone knows if exists a suitable hook for my needs?
