TP4 reusing ADF library migration problem

Question

Hello,
I have an application containing multiple Business Components and View Controller projects.
Common functionality is shared as ADF library between view controller projects. The applicatio was created with TP3 and is working just fine. When ported to TP4, it seems that part of the functionality shared as ADF library is not working.
To be more specific: the login page is using a backing bean to check the authentication details against the database. The following code is working properly:
        appModule =
                (ApplicationModule)((DCBindingContainer)getBindings()).getDataControl().getApplicationModule();But, when accessing the BC module from a phase listener using the following code:
        DataControl dc = event.getLifecycleContext()
            .getBindingContext()
            .findDataControl("SharedModuleDataControl"); DataControl is null.
The same phase listener is working properly when used within the project it was created (and not as imported ADF library)
Once again, this is happening with TP4, with TP3 everything is working fine.
Thanks,
Florin Marcus

Gabrielle,
The root of the problem is that JDeveloper makes a copy of the adf-faces-impl.jar in the WEB-INF\lib directory in your project directory. So what was happening is the project contained to old version of this library that still referenced the "selected" attribute. When you built and then ran the project against the new runtime libraries that no longer had this "selected" attribute, the error occurred.
So the solution to this problem would be for JDeveloper to not copy these libraries into your project directory or to detect that the version has changed and warn you or prompt you to copy the libraries again.
