[xwiki-users] [1.1] Velocity, summing properties

[BOUSQUET Jeremie]

Hello,

 

I would like to perform a sum in a velocity script.

The following works well:

#set ($a = 1)

#set ($b = 1)

#set ($c= $a + $b)

 

$c returns 2

 

But if I modify with

#set ($b = $categoryDoc.getObject("Blog.Categories","name",$bcategory).get("color_red"))

 

... the sum does not work anymore. It seems that $b is considered as a string and gets appended to $a instead of added. The property retrieved "color_red" is of type Number.

 

Is there a way to convert it in order to perform arithmetics on it ? I looked at velocity dev guide but I'm quite confused ...

 

Thanks,
