Configuring Views and Context 107

Configuring Views

When creating a nested view, the Context tab shows allows the user to define additional

context for the nested component. The selected inputs are required in the nested view.

All context inputs of the nested view are read-only.

A context input of a nested view might be converted to optional. This can happen if the

nested view has an action configured that has generated context that is for input which

causes an implicit (optional) context input to be created.

Replacing Views

Since system views are predefined views that are shipped with a WCF-based

application, they may be referred to by other views so the IDs of these system views

should not change. However, if you want to replace a system view with a new view that

is based on a different component, you are not able to edit the view and change its

component type. Instead, you create a new view and then replace the old view with a

reference to the new view.

In order to do this, select the view to be replaced in the Definitions editor, then click the

Remove button. Regardless of whether the view is removable (whether it has

dependents or not), you have the option of replacing the view. If you choose to replace

it, you then see a tree of views that includes only the views that have context inputs that

are compatible with the required context inputs of the view to be replaced. Once the

replace is confirmed, the view that was replaced no longer appear in the Definitions

editor. Any references to it are automatically be converted to refer to the selected

replacement view.

Definitions Pane Settings Tabs

If you have added a new view and are beginning to edit it, or when opening an existing

view, the Definitions pane displays a series of tabs. These tabs enable you to configure

the view definition properties. Each view is defined by a group of settings and each of

these groupings has its own tab in a definition.
