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.

Thanks

Not quite. Use either

`.rootContainer`

or

`.getRootContainer()`

The former is slightly more efficient.

Been a while since I used Vision (why does that article exclude the ())?

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.

@coatl-dev - on that note, been meaning to suggest adding the NetBeans-compliant properties to ignition-api for us layfolks who use VSCode/CPython

Took me a minute to figure out I had to use this `window = system.gui.getWindow('path to window')` to be able to use the `getComponent()` method.
