Having looked at basic theming, creating dashlets and Document Library customization, this session will dig deeper into Share extensions. Topics will include: overriding components, changing page layouts, adding new pages and advanced techniques with dashlets. It is assumed you have a basic understanding of Surf concepts as well as a working knowledge of JavaScript and Freemarker. Familiarity with YUI 2.x and CSS will aid understanding during this session.

- 56. templates – flot-grid.xml
- 57. template-instances – flot-collaboration-grid.ftl
- 58. css selectors - .flot-event-statistics
- 59. Use packages where possible:
- 60. webscripts:
- 62. javascript:
- 65. Sweep of configuration possibilities & hookpoints
- 66. Scope overrides
- 67. I.e “page” overrides “template” but also make “uri” override “template” and “page”. This makes it possible to have “site specific” components on pages.

Notas do Editor
- No matter what version of Share you use: never modify source files.Instead you copy the originals and place them in the web-extension folder to be overridden! This is true for all versions!What happens is that Share always looks in web-extension for what it wants before it looks in the webapps folder.New functionality is also placed in shared/classes but just above the web-extenstion folder.Client side resources needs to be placed in a new .war file and all templates that references them needs to be overriden in the web-extension folder.
