The thing is, TabsForShows (the subcomponent I'm trying to call) _does_
have a key called showID.

Following up on this old thread...
I just had a similar issue: WO claiming a component didn't have an
accessor method for a key when it certainly did. In my case the
tell-tale clue was what WO yelled into the log, just before tossing up
NSKeyValueCoding$UnknownKeyException:
"WARNING: Unable to find component class named <Component Name>. If
this is not intended to be a classless component, check your framework
settings and the contents of your classpath file..."
I don't know if this is the cause of your problem, but my install of
Xcode 1.5 doesn't configure build phases correctly for Display Group
Components added via the little wizard (this is a project created in
xc1.5). There's a note about this problem pertaining to Direct To Web
and Java Client WO project at the end of the Xcode 1.5 rel notes, but
nothing about the DG component wizard. Anyway... Easily fixed by going
to the Application Server target and dragging the .java file for the
component from the Bundle Resources phase over to the Sources phase.
(This could be due to some unknown weirdness on my machine, I haven't
tested the behavior on a fresh Xcode 1.5/WO 5.2.3 install.)
