[TYPO3-dev] Bug in ForViewHelper -> only first element shown

[Michael Bakonyi]

Hello there,

under certain circumstances there seems to be a bug within 
\TYPO3\CMS\Fluid\ViewHelpers\ForViewHelper resulting in an output which 
only shows the first element of e.g. 3 elements to be shown.

We could track down the problem to the foreach-construct on line 108: 
although all necessary elements are present in the "$arguments['each']" 
when entering the foreach its loop is left after the first time already. 
Our guess is, that the pointer of the foreach is manipulated during the 
renderChildren-process as the problem disappears when the foreach is 
quick&dirty replaced by a custom for-construct [1].

I added the main code of the very simple extension to pastebin [2] and 
you can also download the full extension [3]. After installing and 
adding the plugin just create two records of type "Test" for the 
checkboxes to be shown in the list-view. You'll see that only 1 checkbox 
is shown in the frontend (recently tested with introduction-package 
6.1.3 running with PHP 5.4.9 stable extended.

Before filing a bug-report I'd like to ask you to have a look at this to 
be sure that we didn't miss something essential here.

If you need additional information just let me know.

Thx,
Michael
