[TYPO3-project-formidable] Renderlet CAPTCHA: FIX errormessage from locallang.xml

[Hauke Hain]

Hello,

if you set in a XML-File all labels etc you may also want to save the 
errormessage from the captcha there.
So you put something like that in your formidable XML:
<errormessage>LLL:err.captcha</errormessage>

But for some reason only "LLL:err.captcha" will be displayed on the page, 
not the content from the XML.

Here's why:
Open class.tx_rdtcaptcha.php

Find line 145:
    $sError = $this->aElement["errormessage"];

As you can see you get what you typed in your fomidable XML-file. To change 
that just replace the line with the following code:
$sError = $this->oForm->_getLLLabel($this->aElement["errormessage"]);


Have fun!

Hauke
