Background: We have usecase master detail record, when click on edit button and then clicking on cancel button having immediate attribute true and resetActionListener shows replicated rows in detail list. We have implemented the same scenario using HR schema with entity Jobs as master and Employees as detail and received the same behaviour. We are using EJB3.0, and JDeveloper 11.1.1.5.0. We have also checked this issue on JDeveloper 11.1.1.4.0 and found working properly as expected. To replicate the same behaviour we created a sample application using HR schema. Following are the detail of our project and procedures. Creating Sample Application 1. Create new application and select EJB3 and ADF Faces technologies. 2. Create entities from table. Jobs and Employees. (create connection as well with you HR schema) 3. Create SessionBean 4. Create findById method and expose it to local and remote interfaces Create findJobById method Your model should looks like

When I was deploying application to EAR file I was keep receiving error message from my Jdeveloper that "ERROR: No j2ee modules detected in EAR archive.

ViewController To resolve this issue, go to application properties and select Deployment Edit your deployment profile Select EE modules to include in ear file Doing this solved my issue. Cheers...!
