<dsp:valueofvalue-source> [default-value] </dsp:valueof>
Usage Notes
dsp:valueof renders a value in a bean property or page parameter. If desired, you can specify a default value between the open and close dsp:valueof tags, which displays only if the specified source is empty.
Note: If you do not intend to use a default, make sure no text, white space, or carriage return separates the open and close tags.
Attributes
value-source
Specifies the source of the value to display as a JavaBean Component, Page Parameter, or Static value, as follows:
bean="property-spec"Displays the contents of the specified property, where
property-specincludes the Nucleus path, component name, and property name.param="param-name"Displays the contents of the specified parameter
param-name.value="static-value"Displays the specified static value
The value source specification can include a tag converter, such as date or null, so you can display the value in a specific format. For more information, see Tag Converters.
Example
<dsp:valueof bean="Student_01.age" number="##"/>
<dsp:valueof param="currentName">Happy User</dsp:valueof>
In this example, the age property in the Student_01 component is retrieved and converted into a format that renders a number like this: 35. The second tag gets the value of the currentName page parameter. If no value exists, it displays Happy User.
