I'm sure I'm doing something stupidly wrong but I'm not able to store multiple field values in an extension I'm working on.

As far as I know, processRawFieldData() is taking care of the data processing. The passed data array looks like this:

Array
(
    [relation_id] => Array
        (
            [0] => 2003
            [1] => 
        )

    [tab] => Array
        (
            [0] => Deutsch
            [1] => Englisch
        )

)

Which should be stored as two separate entries in a table that looks like this:

`id` int(11) unsigned NOT NULL auto_increment,
`entry_id` int(11) unsigned NOT NULL,
`relation_id` int(11) unsigned DEFAULT NULL,
`tab` varchar(255) NOT NULL

This is how my function looks like:

function processRawFieldData($data, &$status, $simulate=false, $entry_id=NULL) {
    $status = self::__OK__;
    if(empty($data)) return NULL;

    return $data;
}

Nothing gets stored and there are no errors.
What am I doing wrong?

Should the array become? Not sure.

[0] => 'relation_id' => 2003, 'tab' => 'English'
[1] => 'relation_id' => NULL, 'tab' => 'Deutsch'

Best place to debug would be in Field::setDataFromPost which is where processRawFieldData is called from. Are there any existing extensions that do the same thing, that you can look through?

The select field does it like this:

    public function processRawFieldData($data, &$status, $simulate=false, $entry_id=NULL){
        $status = self::__OK__;

        if(!is_array($data)) return array('value' => $data, 'handle' => Lang::createHandle($data));

        if(empty($data)) return NULL;

        $result = array('value' => array(), 'handle' => array());

        foreach($data as $value){
            $result['value'][] = $value;
            $result['handle'][] = Lang::createHandle($value);
        }

        return $result;
    }

Okay, forget about this. There was a typo in displayPublishPanel() which caused a general saving failure. Still it's strange that the error wasn't shown anywhere.
