[TYPO3-dev] bidirectional mm relation via TCA

[stefano cecere]

hi Franz, and thanks.. but i didn't get your point...
i have to tell the "foreign" table TCA, to use the _mm table in "reversing" the uid_local and uid_foreign values!

example:
table tx_myext_a linked to table tx_myext_b by table tx_myext_a_b_mm

TCA for tx_myext_a:
"link_to_b" => Array (		
	"config" => Array (
		"type" => "group",	
		"internal_type" => "db",	
		"allowed" => "tx_myext_b",
		"size" => 5,	
		"maxitems" => 100,	
		"MM" => "tx_myext_a_b_mm",
	)
),

TCA for b:
"link_to_a" => Array (		
	"config" => Array (
		"type" => "group",	
		"internal_type" => "db",	
		"allowed" => "tx_myext_a",
		"size" => 5,	
		"maxitems" => 100,	
		"MM" => "tx_myext_a_b_mm",
	)
),

you see.. a->b works
b->a doesn't works well (the values are inverted because b should use uid_foreign as locals!
