A developer would like to enable end users to filter the data displayed on the related list of an object detail page. How could a developer accomplish this?
What are two ways to invoke a custom web service?
A link to a JavaScript library that can be used in the Visualforce page. When specified, this component injects a script reference into the head element of the generated HTML page.
For performance reasons, you may simply want to use a JavaScript tag before your closing <apex:page> tag, rather than this component.
All messages that were generated for all components on the current page. If an <apex:message> or <apex:messages> component is not included in a page, most warning and error messages are only shown in the debug log.
