One approach you can adopt is that you give all your textboxes the same value for the
name attribute. And have getter/setter for the same name in your form bean. Just remember that instead of handling a
String value, your getter/setter should handle a
String[].
Something like:
This way you don't need to be concerned about how many textboxes are rendered. Be it a single or "n" number of textboxes, the values for each of them will get saved into the String[] of the form bean.
However, you'll need to put in some additional logic either at the client or server side, if it is important for you to map values present at different indices of the String[] to particular labels. Things you need to keep in mind:
1. If the user doesn't enter any value in any one of the textboxes, then there will not be a blank entry corresponding to it in the form bean's String[] variable.
2. The order in which the values are present in the String[] is directly related to the order in which the textboxes appear at the client side.
