[TYPO3-mvc] Extendig of other model fails

[Stefan Kruse]

Hi David and all others,

It works now with the follow ts:

config.tx_extbase{
	objects {
		Tx_In2snippets_Domain_Model_Code.className =
SK\In2snippetsextening\Domain\Model\Code
	}
    persistence{
        classes{
            Tx_In2snippets_Domain_Model_Code {
                subclasses {
                    Tx_In2snippetsextening_Code =
SK\In2snippetsextening\Domain\Model\Code
					
          		}
            }
            SK\In2snippetsextening\Domain\Model\Code {
                mapping {
                    tableName = tx_in2snippets_domain_model_code
                    recordType = Tx_In2snippetsextening_Code
                }
            }
            
    	}
    }
}

I need the objects row.

Could somebody explain where the difficult is behind objects and
persistence.classes and when I have to use what?

Thanks a lot for great helping.

Stefan
