Overview

Every script begins with an initial context that is dictated by the particular script. Quite often, though, you'll want to access information somewhere else within the data hierarchy. That's when context transitions come into play. A context transition allows you to move through the hierarchy, progressing to objects either above or below the current context. These transitions can be chained, allowing you to move through a sequence of contexts to reach the desired destination.

From within a given context, you are only able to transition to a specific set of other contexts. The sections below identify what the valid transitions are for each context.

NOTE! If transitions are utilized that result in an invalid (i.e. non-existent) context, any subsequent target reference will be invalid. If this occurs during run-time, the operation will be ignored and the target identifier will return zero. A suitable error will generally be displayed, but not always. An example of an invalid context is when a pick attempts to transition to a field that does not exist within that pick.
