Hi Lists,

My wonder integration seemed to fail on my existing XCode( v3.1.2) project.
I have 2 frameworks namely:

CoreFramework.framework - contains all my entity classes which I already changed to subclass ERXGenericRecord and seems to build fine without errors.

CoreUI.framework - contains all my WOComponents and seems to build without errors.

CoreAdmin.woa - my application that uses the CoreFramework and CoreUI. All necessary steps to integrate ProjectWonder are done

Are you certain? It does not work, so you should check your assumptions. What are the "necessary steps"? It looks like the EOModel is not getting loaded, if that helps.

and compiled just fine except it produces an error page something like this:



/****** START OF ERROR ******/

Application: CoreAdmin
Error: java.lang.IllegalStateException exception
Reason:
java.lang.IllegalStateException: An Exception occurred while generating the Exception page 'WOExceptionPage'. This is most likely due to an error in 'WOExceptionPage' itself or WebObjects encountered an uncaught exception while creating a Session object.


Below are the logs of the original Exception which occured in Application, then the later Exception in WOExceptionPage.

/****** END OF ERROR *****/


All minimal frameworks needed are already linked to my projects but I couldn't seem to run my application. By the way, I've been using XCode 3.1.2 to all of my WOApplications since I migrated to Leopard and theyre' all fine.

What did I do wrong?

Thanks in advance,
