Java.lang.NullPointerException ADF_FACES-60097 message ***WITH SOLUTION***

Question

Hi Everyone:
We are on JDeveloper 11.1.2 & JHeadstart 11.1.2. When testing an application that had previously been written in 10g and migrated to 11g, then migrated again to 11.1.2 because our database has logical composite keys, we have found that if we manually inputted an invalid value into the inputtext box of a primary key that has an LOV on it, the following message came up.
"java.lang.NullPointerException
ADF_FACES-60097:For more information, please see the server's error log for an entry beginning with: ADF_FACES-60096:Server Exception during PPR, #"
with a random number displayed. We wondered where the java.lang.NullPointerException was coming from and then on a whim, tried to see if it couldn't find the error messages that were previously found in ApplicationResources_en.properties file in 10g. So I manually copied all of the error messages found in the ApplicationResources_en.properties file in 10g, into the end of the ApplicationResources_en.properties file on 11.1.2. There were only about 100+ messages in the 11g version of the ApplicationResources_en.properties file when there were almost 3,000+ messages in the 10g version of the ApplicationResources_en.properties. I then re-ran the job, and the proper error message comes out with no java.lang.NullPointerException message when I input an invalid value into the primary key (+Artransactioncode with this TransCode does not exist).+
Is this a known issue when converting from 10g to 11g?

Hi Everyone:
           I have done some further testing.  We are using a re-usable Business Components .jar file to access our entities.  We import the .jar file into the project and create the ViewObjects and ViewLinks from that .jar file.
            It APPEARS that a test case using the HRSchema and using the Entities & Associates generates the constraint error messages, but when I use the .jar file of re-usable business components imported into the project, those constraint error messages are not created in the ApplicationResources_en.properties file.  I have created two testcases as well as the re-usable .jar file that I can send to you to show what I mean. 
            This behaviour seems to have shown up in 11.1.2 as there was no problem before this.
             Please let me know where you'd like me to upload the testcases.
             Thank you.
