cannot get live templates working

Morning,

I want to include some templates in a plugin. That's all working well, but I have a problem with File Templates with "Enable Live Templates". I can't even get this working when just creating templates in the IDE settings.

I create a template with extension java:

 public class SomeClass {
    // #[[$Something$]]#
    #[[$END$]]#
 }

My understand is that when I do New Java Class, and pick this type, the Something text should be highlighted so that I can overtype it.

Instead I end up with:

All I want to do here is add a template to New Class, which has two or three placeholder variables that the user is guided to modify.

cheers, jamie
