Hi:
what is this error?
com.webobjects.eocontrol._EOCheapCopyMutableArray[300f65]
That is not an error. That is an array fault.
i have a flattened relationship and when i try to do "return
opportunity.company().containsObject(companyItem);" it would give a
java.lang.NullPointerException error.
Which means that either opportunity == null or opportunity.company()
== null. My guess would be the latter. Using an object that you
have not yet inserted into an editing context? Override
awakeFromInsertion or awakeFromFetch and not called super?
so I displayed companyItem and I get the EOCheapCopyMutableArray
thingy.
Well, something is wrong in your code there. opportunity.company()
might be one of those.
companyItem is a COMPANY object while opportunity.company() is to
return a NSMutableArray.
Well, NSArray actually, or any one of its many subclasses.
