for the record.
Frank W. pointed me to the right direction.

In order to use the Label-widget to label OCG and local layers on the
fly it is needed to change this to make mapinfo-tab-files working.
Change from
	$oShape = $oLayer->getShape($nTile, 0 );
to
	$oShape = $oLayer->getShape($nTile, 1 );
in LayerAttributes.php:178

Cheers
	Stephan

PS: just a dirty hack...
