How to get String[] Size in Velocity

[Jackson Farnsworth]

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?

Hi @Jackson Farnsworth

Yes, Jira use velocity.

If both $var.size() and $var.length() comes with the same error,

Then you better check that you pass/access your "var" correctly...

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

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

Hi Jackson,

Confluence uses Velocity, not sure about Jira. Try $var.length()

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[]
