OK Mike, I've now spent 1/2 hour looking for documentation on how you
added the "key" to your .java file in your video from the wod editor.
I'm a newbie to Eclipse and for the life of me I can't find a command
or keyboard shortcut that does that.
This question goes back to the thread about devtools. I have always
tinkered with WO because it was so easy for a non-programmer like me.
I am trying to learn WOLips and Eclipse. One way is by going step by
step through the old Apple Docs and trying to repeat functionality in
Eclipse. The autocompletion nearly replaces the ability to quickly
bind objects to EO attributes. But my question above and your use of
something that's so basic and also so undocumented (unless I am
completely missing something) is probably one reason that non-
programmers are attempting to hold on to the old tools.
You experienced WO/Java programmers should take it easy on the rest of
us hobbyists (as we were called). And instead of lambasting us and
telling us to "Just switch already," help us. I really like WO
because I have been able to quickly build little databased web apps. I
tried using Rails, and found that to be a disaster. The arrogant folks
at 37Signals assumes that everyone who wants to make dynamic websites
must be experienced programmers.
Unfortunately, since I upgraded to Leopard, I had no choice but to
learn to use WOLips. But what so many of you "real programmers" take
for granted, I haven't a clue. Lately, I have seen answers to
questions like, "just look at the Javadocs" with no further
explanation among the many very helpful posts. That sort of "What an
idiot you must be when the answer is right in front of you" is
completely ignorant of the fact that not everyone knows what to do
with the documentation and that some of us, especially me, learn more
by example, than by reading the JavaDocs.
Mike's video is clearly an example that using Eclipse/WOLips is fast,
even faster than the old tools and for the first time I now see how I
can use Ajax in my WebApp. What a great example. More please.

I made a quicky screencast of going from zero (where zero is defined
as "I have WOLips and WO installed") to a super lame hello-world-ish
Ajax.framework app. This is mostly because I wanted to play with
ScreenFlow (which is one of the coolest apps ever made, btw).
Caveats: This is completely unscripted, and just recorded straight
through without any cuts, and to top it off, I didn't actually
really PLAN what I was going do to beforehand, so the couple
uncomfortable pauses are me trying to decide what I actually wanted
to show -- nothing but the highest quality from Team Wonder :) .
This does, however, show the new Add Key/Add Action in WOLips, whose
dialogs will look awfully familiar to WOB folks.

Using Ajax framework should be relatively painless ...
1) Add Ajax, ERExtensions, and ERJars framework to your app
2) make your app extend ERXAjaxApplication
3) make your session extend ERXAjaxSession
4) if you want partial form submission, in your Application
setContextClassName(ERXAjaxContext.class.getName());
5) profit

Everyone,
I have a 5.3 app using stable WOLips that has hundreds of
components and does not currently use Wonder. I have a few sub-
components that have multiple dependent pop-ups, and I do a
submit(); onChange on those pop-ups to refresh the page.
Unfortunately, the pages have gotten pretty big, and the constant
refresh is getting tedious. I was wondering if anyone has a road-
map where I can use a tiny bit of Ajax in a single sub-component
to improve the user experience (it's a maintenance app...so
User==Me). I don't have a ton of time, and can't really risk
moving to 5.4 or reworking the entire app.
Any thoughts?
Thanks,
Ken
