Screencasts
I’ve been playing with the very cool ScreenFlow from vara software this week… Did I mention that it was very cool?
Anyway, I put together a couple of introductory screencasts on using WebObjects and WOLips. They can both be found in the WebObjects Podcasts on iTMS or from the WOCommunity site.
HelloWorld
The first is a short HelloWorld tutorial that introduces:
- Launching Eclipse/WOLips for the first time
- Creating a new WebObjects project
- Project folder structure
- Running the application
- Modifying the application run settings
- Editing components

WO/ProjectWonder/WOLips
The second is a more advanced WO/Wonder/WOLips tutorial that introduces:
- Database setup using Wonder’s Migrations (NOTE: I use WO 5.3 on Leopard -- Migrations are broken in WO 5.4)
- Inline bindings
- WOLips’ Add Action, and Add Key dialogs
- EOGeneration using the Wonder Velocity Template
- ERXKey and chainable qualifiers

Notes:
The response from the WO lists has been very positive, so thank you everyone.
Lachlan Deck asked:
Probably helpful to explain why you’re making the ivars public (i.e., in the absence of getter/setters)
My general thoughts on this are:
If --
- The ivars are only used by the component’s bindings (ie WORepetition item bindings)
- Are used by bindings and are set in only one action or method in the component
- Are never exposed by the api
Then I usually feel OK accessing them directly. If I need to expose the variable via the components API or I need to set the ivars value multiple places in the component then I will make the ivar private and wrap it with accessors.
Comments and suggestions welcome.
