php - Object variable don't display in a twig template -

i find strange behaviour when using twig (v1.23.3)

in templace have array of objects : use dump function display it, :

<pre align="left" style="text-align: left; font-size: 80%"> {{ dump(current_balances) }} </pre> {% key, val in current_balances %}     {{ val.name }} : {{ val.balance | number_format(2, '.', ' ') }} €<br> {% else %}     aucun solde trouvé. {% endfor %} 

the output of dump expected :

        array(2) {       [0]=>       object(record)#20 (3) {         ["name"]=>         string(32) "bank 1 - account"         ["balance"]=>         string(7) "2000.00"       }       [1]=>       object(record)#21 (3) {         ["name"]=>         string(32) "bank 2 - account"         ["balance"]=>         string(8) "1000.00"       }     }  

but output of loop not correct. {{ val.name }} displayed, {{ val.balance }} empty.

i dit kind of loops hundreds of time - code merely cut-and-paste template works.

event more curious that, if invert order of vars in object (as matters), putting balance before name, balance displayed, , not name !

don't know one. of course, template rendered controllers calling models, little part of code.

i think found bug, similar variables not replaced in twig template it's hard tell.

that's not bug ! enable cache in twig , looked @ resulting code. guess ? non-printable char has find way near val.balance. "cat -a" on template file shows :

{{ val.name }} : {{m-bm- val.balance }} m-bm-^bm-,<br>$ 

and result in in compiled template :

$this->getattribute((isset($context[" val"]) ? $context[" val"] : null) 

noticed space before val ?

lost 1 hour one. source problem obsolete frenck keymap in debian....
