Re: attempt to assign value to unknown key

This has happened to me several times. Usually when I have no setMethod(Object value), event though I don't want anything actually set. Adding the appropriate set method has always cleared up the issue, event though the method doesn't actually do anything. In your case, do you have a similar method, such as:

	public setShowID(YouKeyObjectClass value){}

Adding this should do the trick.

This suddenly started happening to me, though in my case it's trying to get the value. I first confirmed that the instance variable is public (Note to Chuck: I re-typed it just to make sure). Then I changed it to private and added accessors. Still no dice. I've cleaned the targets both with Xcode's clean function and by deleting all the build products manually, both before and after I put the accessors in. I'm starting to get a touch frustrated, and I DON'T want to start this project over.

Help!

Reason:
  [<com.webobjects.appserver.WOComponent name: TabsForShows
subcomponents: null > takeValueForKey()]: attempt to assign value to
unknown key: 'showID'. This WOComponent does not have an instance
variable of the name showID or _showID, nor a method of the name
setShowID or _setShowID

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

This can occur if the showID instance variable isn't public and no public access methods exist. public instance variables don't support good object-oriented design, so a protected or private instance variable with public accessors is better.
