[TYPO3-mvc] Cannot update mm-relation (missing tablenames)

[Kevin Ulrich Moschallski]

Hi Franz,

thanks for your reply. I'm looking forward to test your patch, but there's no attachment. Maybe the list cuts attachments or properly you forgot to attach it. Could you please (re-)post it as attachment or as a link, thanks.

Regards,

Kevin

When i now add a relation with extbase all my relations are overwritten and the value for tablenames becomes tx_specialoffersmvc_domain_model_item like the code suggest:
>>> 
>>> $row[$columnMap->getRelationTableRelatedTableColumnName()] = $columnMap->getChildTableName();

>>>                        $row[$columnMap->getRelationTableRelatedTableColumnName()] = $arrayMatchFields[$columnMap->getRelationTableRelatedTableColumnName()];
>>> 		}

I you like you could test attached patch which implements that TCA type and also fixes some other issues I came across with this, but please not that this is experimental code and subject to change before getting implemented in extbase.
