[Typo3-dev] Flexforms and Radio-Buttons

[Peter Huppertz]

Hi List,

I'm trying to use a radio-button in the backend to extend the ms_survey 
Ext. It is configurable using a flexform. This is the way I tried it:
[...]
<answerSaveMode>
    <TCEforms>
        <label>LLL:EXT:ms_survey/locallang.php:ff_answer_save_mode</label>
        <config>
            <type>radio</type>
            <items type="array">
                <numIndex index="0" type="array">
                    <numIndex 
index="0">LLL:EXT:ms_survey/locallang.php:ff_answer_save_mode_text</numIndex>
                    <numIndex index="1">0</numIndex>
                </numIndex>
                <numIndex index="1" type="array">
                    <numIndex 
index="0">LLL:EXT:ms_survey/locallang.php:ff_answer_save_mode_number</numIndex>
                    <numIndex index="1">1</numIndex>
                </numIndex>
            </items>
        </config>
    </TCEforms>
</answerSaveMode>
[...]

And this is the way I try to retrieve the valus in PHP:
$this->pi_getFFvalue($this->cObj->data['pi_flexform'],'answerSafeMode', 
'sDEF');

But this doesn't return the value of "answerSafeMode" ...

By the way, would be nice to have an example for it in the Typo3 Core 
API Documentation?!

Greetings
