Binding Elements

Binding the Input Elements
Each dynamic element contains several attributes. These attributes
determine what happens when the element is displayed or when a form
element is submitted. When you bind an element, you actually bind one or
more of its attributes.
For example, a WOText element (which represents a multi-line text area)
is defined as having two attributes:
• value specifies the string the user enters in the text area.
• name specifies a unique identifier for the text area.
In this tutorial, the only attribute you are concerned with is value , which
represents the string entered by the user in the comments field. You’ll bind
this to the
comments variable. You don’t need to bind the name attribute in this
application. In a later example, you’ll bind more than one attribute of an
element.
1. In the object browser, click the comments variable and drag the cursor into
the Comments text area. Then release the mouse button.
