Hi all,
I'm new to WebObjects and I need a little help. I need to iterate
through a group of EO objects. I'll call them 'baskets' for example.
Each basket object has a to-many relationship to foodObjects. I used
a repetition to iterate through all the baskets and present a popup
asking the user to select one of the foodObjects from each basket.
This all works fine. The problem I'm having is that I don't know how
to get the result (a foodObject) of each popup back into an array or
something so my code can make decisions based on which item was
selected in each basket. I assigned each WOPopup 'selection' to
aSelectedFoodItem. Any help would be great. Thanks!
Just an aside. I am curious that it seems very difficult to find much
support or information online or in books concerning WebObjects.
Apple seems to sporadically update the little information they have at
the developer site. There are only a couple books published in the
last few years and not any well developed, loaded websites. Am I
looking in the wrong places or is WebObjects a dying technology? Am I
wasting my time pursing this technology instead of something "hot"
like ruby on rails or something like that? Don't get me wrong, I
think WO is the coolest fully developed solution I've ever played
with. I am just afraid that Apple is going to pull the plug on it
just as I'm starting to get good at it.

Have you looked at:
http://wiki.objectstyle.org/confluence/display/WOL/Tutorials
http://en.wikibooks.org/wiki/Programming:WebObjects
As a newbie myself, I found both very helpful.
Also you are correct that the choice of published books is limited. I
have purchased the following which I consider akin to the 'Missing
Manual' series in the Mac world:
'WebObjects for Mac OSX' - Joshua Marker (basic good starter; covers the
essentials in a step-by-step example approach)
'WebObjects Developers Guide' - Ravi Mendis (intermediate to advanced
coverage - especially demoing building reusable components and
Direct2Web for rapid prototyping)
'Practical WebObjects: Practical solutions from the trenches...' - Chas
Hill/Sacha Mallais (intermediate to advanced material using Eclipse -
covers many areas of practical interest - EOF and the object graph,
validation, security, localization, etc. and comes with reusable
frameworks that you can plug into you own apps)
All these books are available on amazon.com
