I managed to get the problem working, unfortunately that fix is by doing
something that is against best practices (if I understand them correctly).
To get this to work what I ended up doing was pulling the results from the
search and putting that in the reset of the resultsAction. I am pretty
certain your question about the setting the value on the set and not the get
hit the nail on the head. I will work on the suggestions that you made and
see what progress I can make.
Thanks again so much for all the time and effort.

It's more likely that I don't understand. This is my first struts project
and I am learning as I go.
Here is all of the getters/setters that I have so far. It is quite
possible that I am missing some, but the previous page that I created that
works used only those listed, and it works fine. The main difference being
that the working one only has 1 form on the page, and that I use the reset
method to pre-populate the page (which I have since learned is bad, but I
haven't gotten back to fixing it).
public int getNumProducts() {
return numProducts;
}
public void setNumProducts(int numProducts)
{
this.numProducts = numProducts;
}
public int getNumProducts(int index)
{
if(this.results== null)
{
this.results = new ArrayList();
}
while(index >= this.results.size() +1)
{
this.results.add(new Product());
}
Product p = (Product) results.get(index);
return p.getNumProducts();
}
