Is it possible to use system.db.refresh() on a custom property on the root container?
The reason being, I have a query that returns a datetime, and a Label that is bound to that custom property with an Expression binding. Refreshing the label's binding does not do the job and Ignition yells at me if I try to grab the root for the system function.
Because it is documenting the method names. Methods are called with parentheses. Jython auto-populates properties on java objects that have NetBeans-compliant getter and/or setter methods. Which is why java methods of the format .getSomething() magically also become .something in jython. Pretty much everywhere in jython for pretty much all java classes. (Not an Ignition feature, but a jython language feature.)
Property access is "cheaper" than method calls, so you should use the short forms.
