OAF customizations in 12.2.4
Dear All
I want to develop some OAF customization in Oracle EBS release 12.2.4. I have developed a custom region using JDeveloper (see attachments) and calling that region in my custom workflow. But it is throwing an exception:
oracle.apps.fnd.framework.OAException: oracle.jbo.NoDefException: JBO-25002: Definition oracle.apps.pa.customization.taskwf.server.TaskAM of type ApplicationModule not found
I have imported all regions and copied all class files JAVA_TOP/oracle.apps.pa.customization directory. Therefore this error is not reasonable. Please suggest what version of JDeveloper shall I use or any step should I follow.
