Number of Radio button groups not known until run-time

["Bensman, Jeff [EESUS]" <JB...@EESUS.JNJ.com>]

I'm somewhat of a struts newbie, but I have researched this problem through
all available means I'm aware of, and I now humbly turn to this list for
assistance.

I'm trying to use a Struts ActionForm (v 1.0.2) to deal with a situation
where I don't know the number of radio button groups until run-time.
 
For example, imagine a table where every row is some product a company
sells, and there is a column with a yes/no radio button group. I need the
yes/no decision for every product, but the product list is dynamic and not
known until runtime. 

I tried to eliminate half of my problem by generating the input page
through old fashion means rather than using <html:radio> tags.
Instead, I've tried using iteration to get resulting HTML in each row of
my table that looks like this: 

<input type="radio" name="decision[1]" value="yes" />
<input type="radio" name="decision[1]" value="no" />

and then of course I increment the counter, so 1 becomes 2 on the next
row, and so on and so on... 

I've setup the ActionForm used in the page I post to like this: 

private String[] decision= {};
public void setDecision(String decision[]) 
public String getDecision(int i)
public String[] getDecision()

However, as Struts populates the form it generates a BeanUtils.populate
error. I checked out the source code, and while I see a line that checkes
for the "[" in the name, it doesn't appear to do anything with this 
information.

And remember, these are radio buttons, so each row of my table needs a 
unique name in order for the radio buttons to work as desired.  I can't
give them ALL the same name, or making a decisino on one row would undo
my decision on any other row.

Any ideas how I can do this sort of thing without simply bypassing the use
of the ActionForm?

Thanks in advance for any advice.

BTW, the search of the struts-user list at 
http://www.mail-archive.com/struts-dev%40jakarta.apache.org/ appears to be
down.
For the last several days I get an error message for any type of search.  I
sent the error to webmaster@mail-archive.com as instructed by the error
message
but I haven't heard anything yet.  Does anyone else see this problem?

I think it can help you :

he.org&msgNo=40180

But you'll need to use struts 1.1 !
