oracle.jbo.PersistenceException: JBO-34000: Definition class name missing in XML file of type task Flow

Oracle JDeveloper 11.1.2.3

While doing some copying of Project Source File Content into New Application Source, upon running the page found below error -

oracle.jbo.PersistenceException: JBO-34000: Definition class name missing in XML file of type task Flow

I was copying the content from DataBindings.cpx into new DataBindings.cpx file for a new application & missed to include <definitionFactories/> .

Solution - Open DataBinding.cpx file. Paste the below lines -
<definitionFactories>
        <factory nameSpace="http://xmlns.oracle.com/adf/controller/binding"
                 className="oracle.adf.controller.internal.binding.TaskFlowBindingDefFactoryImpl"/>
        <dtfactory className="oracle.adf.controller.internal.dtrt.binding.BindingDTObjectFactory"/>
        <factory nameSpace="http://xmlns.oracle.com/adfm/dvt"
                 className="oracle.adfinternal.view.faces.dvt.model.binding.FacesBindingFactory"/></definitionFactories>

This should resolve the issue.

How to Resolve JDeveloper IDE Corruption ?

Oracle JDeveloper 11.1.2.3
Windows 7

Recently while doing some work in JDeveloper noticed, Project Hierarchy in "Application Navigator" is overlapping down on "Application Resources" & "Data Control" Panel.

"Data Control" Panel is stuck and not expanding. Reason for these abnormalities is corruption of DefaultWorkSpace file in System Folder.

Solution - Navigate to C:\Users\it_rashid\AppData\Roaming\JDeveloper\system11.1.2.3.39.62.76.1,
Rename or Delete folder "o.jdeveloper". Restart JDeveloper if it is open. This should resolve the issue.
