Hi Justin,
I think you're blaming XCode for pilot error here. Sure, you're trying
to add a key-value pair to a dictionary, but you're still referring to
"id" as a variable. You don't have it defined anywhere within the code
fragment you posted. What are you trying to add to this dictionary?
I noticed that you're also calling this line:
Session session = (Session)session();
But then never actually using this variable anywhere in your code. It's
unnecessary unless you're using custom methods or ivars defined in your
WOSession subclass. If you're just calling a framework-defined method
such as defaultEditingContext()--as you do later in your code--you
don't need to define a local session variable.
XCode refuses to build this, marks the line with the greater than
symbol and the error says "cannot resolve symbol : variable id". All
I'm doing is building an NSDictionary, why would it try to resolve it
as a variable?
Just to clarify this, XCode is an IDE that uses the standard Java
compiler, javac. You're getting simple javac compiler messages that are
legitimate errors that need to be fixed before your code is even going
to compile, much less actually work. Although some seem to have
complaints about XCode, these aren't the problems you're encountering.
I've been following your posts recently on the list, and have noticed
that a number of the issues you're struggling with seem to be related
to your understanding of Java. I know you've got a big deadline, but
perhaps when that's finished you'd find it helpful to work through a
good Java tutorial, independently of anything specific to WebObjects. I
often recommend "Beginning Java Objects" by Jacquie Barker, as it
conveys a firm foundation in object-oriented design, which is essential
to understand the design patterns at work in WebObjects.
Hope that helps,
Colin
