[TYPO3-mvc] Extending of extbase model fails

[Stefan Kruse]

Hi,

i have to reask my question. I want to extend another extbase extension.For
exactly the model. I want to extend the model with some new fields. I
creaste the ext_tables.sql with the new database fields. I create a model
with the new fields and extend the other model. Then I made the mapping in
the ext_typoscript_setup.txt like this:

config.tx_extbase{
    persistence{
        classes{

            \Tx_In2snippets_Domain_Model_Code {
                subclasses {
                    Tx_Skin2snippetsextending_Code =
SK\Skin2snippetsextending\Domain\Model\Code
					
          		}
            }
            SK\Skin2snippetsextending\Domain\Model\Code {
                mapping {
                    tableName = tx_in2snippets_domain_model_code
                    recordType = Tx_Skin2snippetsextending_Code
                }
            }
            
    	}
    }
}

And in the ext_tables.php I made the tca config. The fields are shown in the
backend form. But when I made a debug output from the model the new fields
are not there.

Has anybody a tip? Do is miss something?

Thanks Stefan
