[TYPO3-mvc] Mapping of none extbase tables like pages, tt_content, tt_address and fe_users

[Stefan Kruse]

Hi, 

i make some tests with the extbase mapping of none extbase tables like named
in the subject.

I wonder why I have to mapping the columns by tt_content, tt_address BUT not
by fe_users.

By fe_users I only need to give on the tableName but not explicit the
columns.

Could somebody explain me why this is so?

Regards and thanks
Stefan K.
