How to get String[] Size in Velocity

Question

Having trouble getting the size of a passed in String[] object. I can access individual elements fine with "$var[x]", but trying "$var.size()" results in a NullPointerException being thrown by the velocity template object.

Am I misunderstanding the docs? Or does JIRA not use Velocity 1.7?

None of these seem to work. I just switched to using an ArrayList<String> object. That seems to have worked fine.

Try also ".size()" or ".size"

I've tried ".length" and ".length()", both being displayed as text instead of being interpreted. I've used ".getClass()" to confirm that the variable being passed in is a String[]
