Hi,
I have found a way of doing this but am not sure if this is the best way.
ActionForm:
I am using Vector as collection. I have put indexed getter and setter for
this vector.
This is a vector of beans (MyBean).
in JSP:
The property attribute of html:text is set to a value which is of array
format. The basic idea is when the html is generated the name of the text
field should be of format 'myVector[1].textName' so that appropriate getters
are called by struts when the html is submitted.
Here is the JSP Code,
<%int ij =0;%>
<logic:iterate id="itElement" name="myActionForm" property="myVector"
type="MyBean">
<tr>
<td >
<html:text name="myActionForm"
property="<%=\"myVector[\"+ij+\"].textName\"%>"
value="<%=itElement.getTextName() %>" />
</td>
</tr>
<% ij++;%>
</logic:iterate>
NOTE: set the scope to "session" for the cooresponding action in
struts-config.
HTH,
Vijay

I too have been wrestling with this.
Question:
Does the use of indexed property help this situation?
The problem is that I have no way of knowing how big my lists will be.
I know that indexed properties will help to populate a list with existing
objects,
but I would like to be able to create the list as needed.

I have used a getter that returns a COllection to iterate and a String[] to
write back. So in essence, you draw your cbs and text items, row by row but
you write column by column (notionally)
So in you form:
Colelction names = new ArrayList(10);
String[] nameArray = new String[10];
public Collection getNames(){return names;}
public void setNameArray(String[] s){nameArray = s;}
And in the jsp
<logic:iterate id ="aName" name="yourFormBean" property="names" >
<html:text property="nameArray"/>
</logic:iterate>
Now, nameArry shd be avlbl inthe action (via th eform). There you can place
it in a Vector or suchlike.

Hi,
I use struts 1.0. I am displaying a set of check boxes and textboxes from a
vector in ActionForm using Itereate tag. But when the html form is
submitted, I am unable to retrieve the same into the Vector which is an
attribute of ActionForm.
Could any one give me a solution using struts 1.0.
Thanks in advance.
Regards
VijaY
