Réf. : Re: ActionForm and ArrayList

[Arnaud . PASQUIERS]

Thanks for your help.

But I have the same problem with a String[]... When I retrieve my array,
after submitting my form, its size is 0.
Do you know where I can find a real example?
(My purpose is to update an array of object (not Java objet but custom
object) via a html:form and ActionForm)

In your ActionForm define something like this

 String [] _rows;

String [] getRow() (return _rows)
void   setRow(String [] rows ) { set _rows = rows ;}


Then in your  jsp, each elements of your array use property="row", you may
want to use logic:iterate

It is the idea

-Good luck

ActionForm and ArrayList

[Arnaud . PASQUIERS]

Hello,


I have an ActionForm containing an attribute which type is an ArrayList.
In my action "EditAction" where I prepare data for the form all is ok. I
have the right number of elements in my ArrayList when the form is
displayed in my JSP page.

But  in my "SaveAction" called when the form is submited, when I try to
retrieve the data from my ActionForm I have no element in my ArrayList.
However in the other attribute (String type) of the form, I have the right
data.
Why??

Thanks,
Arno
