  9. QUESTION #1 So do we need a visual JSF editor? 9

  10. What is JSF good for? • migration of application data to and from the UI • UI from a set of reusable UI components • custom UI components 10

  11. JSF versus Rendered Output 11

  12. Who is using JSF? • Developer versus Designer • Developer's evolution • OS Look and Feel dogma • Different roles have different needs 12

  13. Developer Role – what is important? • Data bindings • Conversions • Validations • Error messages • Localization • Navigation 13

  14. Developer Role – what is NOT important? • Layout • Components • Colors, fonts, styles 14

  15. WYSIWYG? No, thank you. • Wrong role focus • Missing HTML render • Imprecise code 15

  16. Q.1: So do we need a visual JSF editor? YES ! – JSF applications are data driven – JSF language is designed for tooling – Visual editor improves productivity – Number of visual editor addicts 16

  17. QUESTION #2 Have tool providers failed ?? 17

  18. Tools – Visual Web Pack • Timing • Scope 18

  19. Tools – Visual Web Pack (Cont) - sloccount() • Total Physical Source Lines of Code = 450,000 • Development Effort Estimate (Person-Years) = 120 • Schedule Estimate (Years) = 3.3 • Estimated Average Number of Developers = 37 • Total Estimated Cost to Develop = $ 16,523,003 19

  20. Tools – Visual Web Pack (Cont) • Absolute Layout • Woodstock + ICEFaces • Database integration 20

  21. Observation #1: Rich component metadata Do I have parents? Can I have children? <x:foo/> What do I render? Which component family is mine? What about my facets? • JSR-276 JSF Component Metadata • JSF 2.0 Composite Components 21

  22. Observation #2: Component Rendering • Arbitrary output of component renderer • JSR-276 JSF Component Metadata • Missing Java native HTML renderer 22

  23. Observation #3: Layout Component Rendering • Mapping source to output • javax.faces.context.ResponseWriter 23

  24. Observation #4: Layout Component vs Drag'n'Drop • Description of drop areas • Description of drag handles has 13 drop areas 24

  25. Observation #5: Layout Options • HTML/CSS based layout • Absolute Layout • h:panelGrid, af:panelFormLayout 25

  26. Matisse parallel • Matisse = Swing GUI designer for Group layout • Good tool + Good layout manager • 70-80% satisfaction threshold 26

  27. Other tools • JDeveloper (JSF/ADF) • MS Dev Studio (ASP) • Window Builder (GWT) • MS Dev Studio (SilverLight) 27

  28. Q.2: Have tool providers failed ?? No, not really. – Tools tried their best – Missing HTML renderer – Hindered by JSF issues – Missing layout abstraction 28

  29. Q.3: Should we blame JSF itself ?? Well ... – Lack of support for design time editing – JSR-276 JSF takes too long – JSR 273 (Design-Time API for JavaBeans) dropped in part. 29

  30. Q.4: Should we blame component providers ?? Well ... – Dependence on tools not really. 30

  31. and my answers are: • Is visual JSF editor needed ? • Do developers prefer text editor ? • Have tool providers failed ? • Should we blame JSF itself ? 31

  32. Summary: JSF does need a visual editor • To achieve that following needs to be done: JSF Tools Providers Any component works   Layout abstraction    WYSIWYN  (what you see is what you need) 32

  33. Practical experience from implementing the new generation visual JSF editor for NetBeans IDE 33
