Creating CHA hierarchies

A CHA hierarchy is a set of two or more CHA contexts arranged in a tree structure. The root context has one or more child CHA contexts, these child contexts may have one or more children, and so on.

To create a CHA hierarchy:

  1. In the Editor view, select the CHA tab.
  2. From the Connection palette, select Connection.
  3. Click the parent context. This action highlights the parent.
    Note: The CHA Editor does not permit circular connections or multiple parents.
  4. Click the child context.

Repeat the procedure until you have created the entire hierarchy.

Note: The root context has a null value for its parent attribute.
