Appreciate if someone can help, as i am struggling to resolve the issue for last 3 days.
Requirement: In our application there is a custom Object created name 'Vehicle'. There is another junction object named Vehicle Relationship. 'Vehicle Relationship' has lookup relationship with Accunt and Vehicle. Requirement is to open a VF page(VF Page1) by calling a button in the Vehicle screen. And it will display all the relationship it has with customers. In this view customer would like to have 'Radio' button against those relationship records, so that only 1 record can be selected. Once you can click on a button in this VF page 1, it should navigates to another VF page2 and display the relationship records for user confirmation.Both the VF page is using same custom controller. And both VF page is not Using any standard controller. 

Problem i am facing: I configured the functionality using wrapper class. When i am using 'Checkbox' in the first VF page, it is able to correclty navigates to the second page and showing the records in VF page 2. But when i am using the 'Radio' button on VF page 1, after clicking button VF page 2 is not showing any records. When i am selecting the records with Radio button i am passing the paramer to controller. Seems issue in Radio button selection records.

Can you please help me why for Radio buttion i am not able to retrive records in VF page2. I am not giving the code for 'Checkbox' here as it is working fine. Sharing below the codes for 'Radio' button selection.
