Can't pass variable to predefined function in

Question

I am trying to create a live template where the second variable is simply an uppercased version of the first variable. The predefined function capitalize(String) seems like exactly what I need but I am at a loss as to how to actually pass the variable in. Every time I try to set the parameter in the expression, it just resets to String.

Template Format:

What I think should work:

But every time I tab out of the field, it just reverts to:

How do I get class to take instance as input and capitalize it?

In addition, there is a request for rethinking this dialog:

So at the moment you may hit 'Enter' after changing the parameter from 'String' to 'instance' (it will be applied) or type the whole expression manually.

Answer 2

The solution is to hit the OK button with your mouse after setting the field. Do not hit enter or tab.
