TYPO3.Fluid

Somewhere in renderChildren the {some_digit} placeholders are being removed.

I traced it so far and can't go further as I don't know how to debug the closure function.

To be clear... the example from the flow3 documentation guide:

<f:translate source="someLabelsCatalog" arguments="{0: 'foo', 1: '99.9'}>Untranslated {0} and {1,number}</f:translate>

becomes:

Übersetzt  and 99,9

I don't know if maybe this was necessary at some step and is related to some important design decision or if it is a glitch.
If it's a glitch I hope someone can find it.

Otherwise I would suggest creating a StringFormatter like I did for myself, so one can then use:

<f:translate source="someLabelsCatalog" arguments="{0: 'foo', 1: '99.9'}>Untranslated {0,string} and {1,number}</f:translate>

Here is the StringFormatter

<?php
namespace TYPO3\FLOW3\I18n\Formatter;
