TopLink ADF Faces Tutorial - Object Generation Error

Question

Hi,
I'm trying to work through the tutorial "Build a Web Application with ADF Faces and Oracle TopLink" (http://www.oracle.com/technology/obe/obe1013jdev/masterdetailedit_adftoplink/endtoend_toplink_adffaces.htm#t2), but I am stuck at the last step of "Creating the Data Model Using Oracle TopLink (http://www.oracle.com/technology/obe/obe1013jdev/masterdetailedit_adftoplink/endtoend_toplink_adffaces.htm#t2s2).
When I hit the Finish button of the Create Java Object from Tables wizard, I get the following error:
java.lang.NullPointerException
     at oracle.ideimpl.log.TabbedLogManager.getMsgPage(TabbedLogManager.java:101)
     at oracle.toplink.addin.log.POJOGenerationLoggingAdapter.updateTask(POJOGenerationLoggingAdapter.java:42)
     at oracle.toplink.addin.mappingcreation.MappingCreatorImpl.fireTaskUpdated(MappingCreatorImpl.java:1049)
     at oracle.toplink.addin.mappingcreation.MappingCreatorImpl.generateMappedDescriptorsForTables(MappingCreatorImpl.java:231)
     at oracle.toplink.addin.mappingcreation.MappingCreatorImpl.generateMappedDescriptorsForTables(MappingCreatorImpl.java:201)
     at oracle.toplink.addin.wizard.jobgeneration.JobWizard$1.construct(JobWizard.java:401)
     at oracle.ide.util.SwingWorker$1.run(SwingWorker.java:119)
     at java.lang.Thread.run(Thread.java:595)
It appears the wizard is having a problem opening or displaying log messages?
I searched this forum and found two posts about this problem:

but no solutions or suggestions.
Hoping a JDeveloper guru can help me out.
TIA,

Sorry - I didn't look hard enough.
Found the answer here:
Re: Business Tier: Toplink: Java Objects from Table: Object Generation error.
Would be nice if someone would update the tutorial with a step to compile the datamodel project before attempting to create the java objects.
