Overriding attributes of a collection's reference

In a collection, you can override the attributes of any of the collection's reference sub-elements. The override is local to the collection and does not affect other instances of the data element being referenced. This enables you to, for example, specify a different implementation class for this collection only. The Property View displays the overridden attributes and their values in the Override property.

To override attributes, perform the following steps:

  1. In the CHA Data view or Outline view, right-click the collection in which you want to implement the override.
  2. Select Override Attribute.
  3. From the list of data elements contained within the collection, select the one that has the attribute you want to override.
  4. From the list of attributes, select the one you want to override.

    Select the attribute you want to override.
  5. In Properties View, expand the Override property and expand the data element containing the attribute you want to override.

    Expand the data element containing the attribute you want to override.
  6. Click the attribute.
  7. Type or select the override value.

To cancel override attributes, perform the following steps:

  1. In the CHA Data view or Outline view, right-click the collection in which you want to implement the override.
  2. Select Cancel Override Attribute.
  3. From the list of data elements contained within the collection, select the one that has the attribute you want to override.
  4. From the list of attributes, select the one you want to override. Then the overriding of attributes is canceled.
