Property not found on object of type

Question

I have a simple question:

I have a NSManagedObject subclass that I've been using for some time and it was working perfectly fine. Today I added a new property to it with the corresponding iVar. The property is a simple (nonatomic,retain) NSString *. And as normal i added @synthesize to the property to generate setter and getter functions. However, there is no way i can use the newly defined property!!! I keep getting "property not found on object of type" error and my build fails.

Here are a few chunks of code that will clear things out:


    //import the core data header first CoreData/CoreData.h

    @interface Contact :  NSManagedObject

    {
       NSString *contactID;
       NSString *firstName;
       NSString *myDevMod;
    }

    @property (nonatomic,retain) NSString *contactID;
    @property (nonatomic,retain) NSString *firstName;
    @property (nonatomic,retain) NSString *myDevMod;

    @end

and the corresponding .m implementation:

    #import "Contact.h"

    @implementation Contact 

    @synthesize contactID, firstName, myDevMod;

and the code that uses the Contact class:

    #import "Contact.h" //at the start

    Contact *aContact = [[Contact alloc] init];
    aContact.contactID = someId; //works perfectly fine
    aContact.firstName = someName; //works perfectly fine
    aContact.myDevMod = @""; //THIS IS WHERE THE ERROR OCCURS!!
    [aContact doSomethingHere];
    [aContact release];

What do you think could be the error??

Thanks in advance for your support.

Are contactID,firstName and myDevMod attributes of your managed object, or separate properties that are not part of the core data structure? — jrturton
Also do you still get the error assigning a string object ([NSString stringWithString:@""]) instead of a static @""? — jrturton

Weirdly the site won't let me add a comment so :

comment: Sounds odd. First thing I'd try is removing the @property lines and @synthesize line - so the getters and setters are created automagically. Also try: aContact.myDevMod = someName; to see if that actually works - might shed some light.
