[TYPO3-mvc] RFC #10487: MM_match_fields not respected on UNIONs

[Franz Koch]

Hey there,

this is a SVN patch request.

-----------------------------------------------------------------------
*Type:*		Bugfix
-----------------------------------------------------------------------
*Bugtracker:*	http://forge.typo3.org/issues/10487
-----------------------------------------------------------------------
*Branches:*	trunk
-----------------------------------------------------------------------
*Problem:*

Extbase currently doesn't respect MM_match_fields for UNIONs. Those are 
f.e. created by queries refering to properties of childObjects in their 
constraints.

Example:
$query = $this->createQuery();
$query->matching(
	$query->equals('childObject.propertyName', 'someValue');
)->execute();

As soon as the relation to the childObject depends on MM_match_fields 
you currently will get wrong results.

-----------------------------------------------------------------------
*Solution:*

Simply add the MM_match_fields to the UNION WHERE statement.
-----------------------------------------------------------------------


PS: still looking for a nice RFC template and experimenting ;)
