[TYPO3-mvc] Domain model records without pid-column

[Dennis Ahrens]

Hi again,

I've had a deeper look into how extbase handles other fields from tca 
and how the mapping is done for them in the persistence backend.

You can find a small patch
http://prserv2.rz.fh-hannover.de/dahrens/extbase_r2279_models_without_pid.diff
which changes the behaviour in the following way:
Each table has to define
$TCA['fooTable']['ctrl']['pid'] = 'pid-column-name';
If the pid-column should be respected.

If this field isn't set the pid is not handled by extbase when inserting 
a new row.

Pro:
  - the TCA configuration behaves like the others around (tstamp, 
crdate, etc.)
Con:
  - breaking change, because each model using the pid has to define it 
in TCA's ctrl-section

Any opinions?

regards
Dennis
