Hi everyone,  
I have a vision template and from “ **power table** ” in this template, under “ **Extension function** ”, I want to _ **access to one custom properties** _ of my Template which is under root container.

Any idea?  
to access to root container’s customer properties, it is:

**event.source.parent.getComponent().NameofCustomProperty**?

For event routines (no `def` at the top), it would be `event.source.parent.NameOfCustomProperty`. In other routines (with `def`), use `self.parent.NameOfCustomProperty`.
