Ok,
After I did some fucking around with the code, I figured that it has to do with
Code:
out.println("<option value=\"" + ((SupplierBean)suppliers.get(i)).getSupplierID() + "\" " + selected + ">" + ((SupplierBean)suppliers.get(i)).getCompanyName() + "</option>");
When I left it in there, the page wouldn't load 100%, but when I took it out, it did??
