Hi,
Thanks for replying... I did stumble onto the index extension
in my search, but i thought i could manage without!
I will try to do as you describes, thanks a lot!

You need to do two things.
First, you need to generate appropriate names for your input fields. If you
use the current Struts tags then all the occurances of your two fields in
the example below will generate names of firstName and lastName. What
you want is to generate names in the format contactDataVector[x].firstName
and contactDataVector[x].lastName, where x is the index number of the
field. Dave Hay has posted a set of modified Struts tags which generate
these names on Ted Husted's site:
http://www.husted.com/about/struts/resources.htm#extensions - Indexed
Tags
Secondly you need to provide the appropriate getters/setters in your bean
and ActionForm. Obviously in your bean you need setFirstName() and
setLastName() methods - additionally you need the following getter in your
ActionForm:
public ContactData getContactDataVector(int index) {
return (ContactData)(contactDataVector.get(index));
}
Hope this helps.

Re: Problems with iterate
Let us see if I got this .
getFirstName ( ) and getLastName( ) should be in the ContactData class and
not needed in the ActionForm
And in the Form bean one should have only getContactDataVector(int index)
method as u said .
In reset() method of the ActionForm u can instantiate the ContactData class
and vector of ContactData class if it is null .
So that in the jsp file u can have contactDataVector[i].firstName and
contactDataVector[i].lastName fields .
I think when u submit html:form then automatically ur FormBean's
contactDataVector will be intialized
1. by calling reset method first where u intialize the vector of contactData
. Then
2. by populating the ActionForm data ( contactDataVector) with the values
from form fields
Please correct me if I'm wrong .
