Hi!

I have an ArrayList that i display in my jsp with an iterator (one textfield by iteration), but when my validate found an error (missing field, ...), i lost all my data.
So, i put a <s:hidden> with the name of my ArrayList, now, i retrieve my data BUT struts put all my data in ONLY ONE textfield and separated by a comma (,).

Someone has an idea? How to display my List correctly after the validation?

Thanks in advance!

Well..

- I have an ArrayList (of objects):



- I display this ArrayList in my JSP.



->

- But if i have an error in my validation, my data look like that (1 textfield instead of 4 textfield)

- >

My question is: how can i retrieve my data (if i have an error in my validation) in 4 textfield different like the first display?

Hi Fabian,

let me explain you proper...

myList = getMyList();



let say your myList contains size 5. So, when you are iterate through your list it will iterate 5 times.... now what happens each times

<s:textfield name="beginDate" />



your <s:textfield contains same name name="beginDate" . So when you post your form your ><s:textfield contains all five value...

that is why it shows look like this... So, just each iteration you have to change your ><s:textfield name property.... >

Thanks, Nishan Patel

Yes, but I need that textfields have the same names to retrieve each value after the submit

Fabian, first of all remove the hidden text field. Now I'm really confused what you are trying to achieve here. Your textfield's name is beginDate and you are iterating over myList. So when you submit your form and there is a validation error, how are you expecting your values to be retained. Maybe I'm missing something. Can you show the source code of the Action. What I think is that when validation fails, then your myList is empty and thus you don't get any text fields because there is no myList to iterate over...

Actually I don't understand the structure of your application. Is it like this. There is an action Action1 which has a property myList. That action's success forward page is MyJsp.jsp (which you showed us here). That JSP has a form whose target is Action2 which has a property beginDate...
