[TYPO3-mvc] desperation with f:form.checkbox

[Philipp]

Hi

I really thought i finally managed to work with fluid. Having to write a viewhelper for each and every babyshit requirement seems okay to me.... But what really makes me freak out is the f:form.checkbox viewhelper

No matter how i want to use it, everytime it throws me some other error.

This time a assign an array to the view set it as object for my form-viewhelper. Just like:
<f:form object="{search}" objectName="search">

Okay, then i need this checkbox and place it like
<f:form.checkbox property="filtergroups.2" value="{category.uid}"/>

In my controller i assign the filtergroups-property as array to search. For each filtergroup i have set in my plugin i additionally assign one array to the filtergroups array, makes my search-property looks like:
search [array]
- filtergroups [array]
-- 0 [array]
-- 1 [array]
-- 2 [array]

so search.filtergroups.2 is definitly an array, if i do a f:debug i get array (empty)

But anyway...... the checkbox viewhelper tells me:
Checkbox viewhelpers can only be bound to properties of type boolean or array. Property "filtergroups.2" is of type "NULL"

I really have to say: I dont have time for those fluid problems anymore.
Can someone tell me why this happens at that point?

i mean, a template engine is supposed to make templating easier... i really appreciate the work you put into the typo3 project but why didnt you just use Twig or something really approved? Fluid is completely underpowered and also pretty slow.
