Need advise how to redirect
Hi there,
I am jotting down the requirement
1.A jsp which contains a datatable
2.User can update or add some new records in the datatable
3.user can nevigate to some other page from this current one
4.if user will click on the nevigation button, and the form is already dirty, the application should save the data first and then will nevigate to the next one, if not user to nevigate to the next page.
To implement the point 4, I am facing some problem.
On the click of the submit button, I first tried to check whether the form is already dirty and if so then tries to save the form data and then redirecting to another page by calling the initLunch method of the managed bean(of the next page).
But my the WSAD is crashing with the following error:
