[TYPO3-mvc] Condition in if-ViewHelper quesion

[Thomas Hempel]

Hi,

I'm currently trying to understand how the the if-ViewHelper works. 
Unfortunately I can't find the place where the condition argument is 
parsed and checked. Can somebody please point me to a direction?

The background for this question is that I pass a negative value to a 
variable and check that in an condition. The weird thing is, that the 
result is always true. I somehow think that the value is not treated as 
integer but as a simple string.

Here is what I mean:

In the controller:

$this->view->assign('value', -1);


In the Fluid template:

{value}
<f:if condition="{value} > -1">
	<f:then>
		is greater than -1
	</f:then>
	<f:else>
		is smaller or even -1
	</f:else>
</f:if>


The result is:

-1 is greater than -1



Greets,
Thomas
