I'm trying to pass parameters from a client event script to a property change window. And I'm getting the error that "Property (blank) doesn't exist in window." Essentially I believe it's telling my that (blank) isn't a root container property in the object. When printing "nameOfContainer = system.gui.getWindow('ParentContainer').getComponentForPath('Root Container.Blank')" is I print nameOfContainer.name, it prints Blank. How do I pass a dictionary into a definition of this object in this format. system.nav.openWindow(pathToObj, {nameOfContainer.name : nameOfThing}) without flagging root container issues?

Share your code, or a simplified version that demonstrates your problem. Please don't use a screenshot. Instead, after pasting the code, highlight it all and click the "Preformatted Text" button in the forum's comment editor.

Also post the "full" error message you're getting (again, in a formatted text block).

Also note that the various `.getComponent*()` methods don't return properties. They return components. You probably need to leave off `.Blank`, then access `returnedComponent.Blank` in your code.

If working with dynamic property paths, you will likely need to use python's `getattr()/setattr()` builtin functions for that last path element.
