The IS_TRUE element has the following attributes:
Attribute Name |
Required |
Default |
Description |
---|---|---|---|
NAME |
Yes |
The name of the SERVER_INTERFACE instance to use as the source of the property value. |
|
PROPERTY |
Yes |
The name of the property being accessed. It must be a Boolean value. |
In the majority of cases the NAME and PROPERTY combination will reference a display-phase server interface property. However when a page submits to itself using an ACTION_CONTROL with a child LINK element that has the PAGE_ID set to THIS (e.g., a search page), properties of the action-phase server interface can be referenced. When the page is first displayed the action-phase server interface will not be in scope and the property is treated as if its value is false. When the page is submitted, the action-phase server interface will be in scope and the referenced property will be evaluated as normal.
