I have a JSP which has two buttons, ADD and SAVE. I need to display a row with three Textboxes with the first text box pre-populating a value from database (some thing like sequence number). The user enters the remaining two boxes.
When I press the ADD button a new row is to be displayed with the three textboxes, the first textbox gets a value from the data base. When I press SAVE, the form is to be submitted completely with the data filled by user and the generated sequence numbers.
What I am now trying: I have an ArrayList kept in the request scope in the previous action. This array list has only one Value Object with three parameters and their getter/setter methods. I am using <logic: iterate >tag in my current JSP to iterate over the array list. It is properly showing one row. In my second action I have a switch case to identify that ADD button was pressed and I am getting the ArrayList from session object. Here I am adding a new Value Object to the list, and setting it again in session scope.
I t is displaying properly that is a new row is added when ever I press the add button. Things are fine so far.
The problem: 1.When I press refresh(browser) button, it is still adding a new row. 2.I could not get he ArrayList from the form object. Can any one point to some references/ examples similar to this? Regards, Nagesh
