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();
}

for numProducts indexed property. And i dont understand why are you
populating blank values in the getter methods..I mean you should be doing
that in your setter methods..something like
public void setNumProducts(int index,String val) {
while(index <= results.size()) {
results.add(new Product());
}
Product p = (Product)results.get(index);
p.setNumProducts(val);
}
maybe i dont understnad the context of your problem properly, but this
what
i do with indexed properties.
As far the error message here is what I recieve:
