[TYPO3-dev] Versioning and foreign field as label

[Michel Georgy - 4eyes GmbH]

Hi all, 

There seems to be a little Problem if you work with versioning/workspaces and have a intermediate table where 
the label of this table is a foreign field. 

If you create a new version in DRAFT Workspace there will be generated 2 records in database, an actual draft version and 
a placeholder. And here's the problem in "class.t3lib_tcemain.php:883":

	$newVersion_placeholderFieldArray[$TCA[$table]['ctrl']['label']] = '[PLACEHOLDER, WS#' . $this->BE_USER->workspace . ']';

As the label is a foreign field and therefore just a integer in our case, an error is shown because insertDB now tries to 
save a string value ("PLACEHOLDER, WS#1") to the Integer field. 

As a workaround i changed the type of the column to varchar. In my opinion just suitable as a tempory solutions. 

Did i miss something? Any suggestions for better solutions or confirmations for this problem are appreciated. 

Best regards

Michel
