ScriptRunner post-function: Auto create Subtask, conditions help

[Timothy Ryner]

I am trying use Scriptrunner's "Create a sub-task" post-function to automatically create a subtask on a particular transition when number custom field (named "# Maps") has a value above 25.  We'd like to create a subtask for checking maps when the parent issue indicates there are a lot of maps.

I can't figure out the syntax for the post-function's condition.  Below is basically what I need, but of course, the ">=" isn't valid.  

cfValues['# Maps'] >= '25'

Jira Server v7.9.2
ScriptRunner v5.4.12

Any ideas?  Thanks in advance!

Even though your custom field is numeric, perhaps the cfValues[] array treats all custom fields as strings. Try casting to an int, i.e.

(int)cfValues['# Maps'] >= 25

Gave it a quick test, and that appears to have done the trick!

Much obliged!
