[TYPO3-english] Flexform questions

[Robert Wildling]

Jigal - thank you VERY VERY MUCH!!! In general, my little scripts now 
works and thanks to your explanations I can read and understand the 
documentation better! Again: THANK YOU!!

Could you maybe help me understand the following behaviour?

When the debugging statement after the loop is commented out:

...
	while ($row = $GLOBALS['TYPO3_DB']->sql_fetch_assoc($res)) {
       		$config['items'][] = array(0=>$row['header'], 1=>$row['uid']);
       		$i++;
       	}
-->   	debug($config['items'],'configItems',__LINE__, __FILE__,5);
	return $config;
...


the debug page contains twice the same result. This does NOT happen, 
when only the first field is filled in in the flexform (which indicated 
the Page ID). But as soon as the second field (the column indicator) 
appears (ONLy appears, not even has a value), the debugger throughs 2x 
the same result.

The behaviour is the same, no matter how many more field I add to the 
Felxform...

Is this an expected behaviour? If so, why?


Thank you!
Regards,
Robert
