[TYPO3-mvc] $query->statement('MYQUERY') doesn't count for <f:paginate />

[Domi]

Hello List,

I just using the <f:paginate /> over an queryResult but have following 
error:

Because of the use of

$query->statement('MYQUERY WITH SOME WHERE CONDITIONS');

If I make a count over $result->count() it counts all elements without 
my statement conditions. This results an incorrect <f:paginate />, 
because the count is wrong.

How shall I deal with $query->statement(), that the count is right for 
the view?

Thanks!

Dominic
