Introducing the Web Component Framework 41

The User Interface

Property: Title

Title has the same choices for its content as Item. The title appears as a header in the

bounding box around the label, but only if you choose to show it when adding the label

to its parent view.

Property: Background

This group of properties controls various aspects of the label’s background. See the

reference pages for additional details.

Property: Error Renderer

Choose one of the available error renderers.

An error renderer is invoked if the retrieval of the specified data generates an error at

runtime.

Property: Null Renderer

Choose one of the available null renderers.

A null renderer is invoked if the retrieval of the specified data returns null.

Flow

The Flow tab allows you to specify the actions that can be performed when a user clicks

the label or just hovers over it.

For more information, see “Configuring Flows for Views” on page 115.

There are additional properties under Page Options and Portlet Options that you can

look up in the reference page for the label.

From this example you can see that even a simple component such as a label has many

configurable properties and actions. This overview of the possible settings for a Label

should give you a notion of how you would use the definitions editor to set properties on

a Web Component Framework entity.
