Java Development Tools

Hi All,

I am using jdeveloper 11.1.1.5.

I have 3 taskflow with pages:-
taskflow1- Page1.jspx
taskflow2- Page2.jspx
taskflow3- Page3.jspx

On Page1 I have 2 text boxes (First Name and Last Name) and 1 button Search1. Lets say User entered First Name and click on Search1, then I am navigating to Page2.
On Page2 I have 4 text boxes (First Name, Last Name, Email and address) and 1 button Search2. On click of Search2 I fetch data from database depending on the entered value(First Name, Last Name, Email and address) and display it in a table in Page3.
On Page3 I have a table which contains the results and a button select. And I have a selectBooleanRadio on each row of the table and I have a select button on this page.

On click of select button I get the selected row from table and after that I have to move back to Page1 directly, so I am doing following:-

On Click of select button on page3 I am getting the selected row from the table and navigating back to Page2 - On Page2 on returnListener of Search2 button I am again navigating back to Page1 - On Page1 on returnListener of Search1 button Finally I have to set the FirstName and LastName.

But I am getting following error while navigating from page3 to page2.

I have a beforePhase method on page2 which I have written in MyBean class. I have registered MyBean to my taskflows but I am getting following error:-

Scope of MyBean in TaskFlow1,TaskFlow2,TaskFlow3 is request.+

If I am removing the beforePhase method on page2 I am getting following error:-


NullPointerException:-
