[TYPO3-project-formidable] Why are the template methods ifEmpty / ifNotEmpty commented out?

[Hauke Hain]

Ok,
I think I know why.
   case "ifNotEmpty": {

    if(tx_ameosformidable::templateDataAsString($mData) === "") {
     return TRUE;
    }

    return $mData;
    break;
   }

If TRUE is returned the part that is empty is shown.
And if you set it to FALSE:
   case "ifNotEmpty": {

    if(tx_ameosformidable::templateDataAsString($mData) === "") {
     return FALSE;
    }

    return $mData;
    break;
   }

It works like it should, but a JavaScript exception arises.

Can you fix this problem or tell me how I can achieve that a part of the 
template is only shown if
storedData("dbfield") is not empty?

Now I use:
<!-- ###storedData("backup").ifNotEmpty() perimeter### begin-->

But also
<!-- ###storedData("backup").isTrue() perimeter### begin-->
would be possible if isTrue would use "==" instead of "===", but thats not 
really a solution...


Kind regards,
Hauke
