[TYPO3] Accessing flexforms from backend module

[Steffen Gebert]

Hey list,

Is there any way to use flexforms in a backend module AND later access it's
values in the same backend module?

We want to extend aux_newsmailer to enable user to select records, which
should be sent and so have to select records in BE and read out (at
sending), what was selected.

Because of it's a backend module, we can't access pibase::get_FFValue
(right?) - so is there any solution or any better way to give user the
ability to select multiple records out of a list (of tt_news records).
