Writing a DHTML JSF graphical component

• DHTML component is
• Server-side component
• HTML generation
• Javascript for client side interactions
• Creating a JSF component
• Derive UIGraphic to provide a JSF component that
  wraps the graphical component
• Implement a renderer that generates the HTML and
  the necessary script
• Create the tag in the tag library
• Provide any additional meta-data and code
  required for the component as well as the IDE if
  being used

Sounds simple but

• Script dependencies and includes must be handled
  correctly
• Example an overview has a reference to a
  view, the script object for the view must exist
  before the overview can access it
• Hence dependencies between the order that (parts
  of) components are renderered
• Requires script for incremental refresh in order
  to build a better user experience
• Renderer generates script proxies that call back
  to a secondary servlet that handles all requests
  for images outside the normal JSF cycle (whilst
  waiting for a better solution)

Component Vendor JSF Vision

• IDE support will decide the success of JSF
• Simple component deployment
• Need a JSF component integration framework for
  integration into a JSF compliant IDE
• Provide support for incremental refresh
• Standard JSF components that are independent of
  the renderer
• Render based on client capabilities
• Use more advanced rendering (e.g. SVG) for more
  graphics intense interfaces
