[TYPO3-english] Function/class 'b' was not prepended with 'user_'|

[Jeppe Donslund]

I get this strange error:

Function/class 'b' was not prepended with 'user_'|

and it disappears if comment out the marked line:

$confx = array(
   // Link to current page
   'parameter' => $GLOBALS["TSFE"]->id,
   //'no_cache' => 1,
   // Set additional parameters
this one --->  'additionalParams' => 
'&tx_mstplugin_pi1[vote]='.$vote.'&tx_mstplugin_pi1[spot]='.$spot, 
<---------- this one
   // We must add cHash because we use parameters
   'useCacheHash' => true,
   // We want link only
   'returnLast' => 'url',
);

$url = $this->cObj->typoLink('', $confx);
print $url;
return $url;


What can be wrong?

Best regards
