Hi all I have been working on this probelm for the past couple of days, and
don't seem to be making any progress on it. I am fairly certain it is a
problem with my understanding of struts, and as such it makes it quite
difficult for me to solve the problem myself.
I am trying to use a textfield and pull values from it. The following
explains the scenario. User clicks on a page, page loads with a form that
has a textfield. User enters search criteria and submits form. This works
fine. Page returns with the search form and textfield, as well as a second
form that displays the results of the search. This also works fine. The
user then goes through the results filling in numbers for each result
indicating how many of each they would like to order and then submit the
form. This is where the problem results. I end up gettting an error from
the page anytime I submit the form where there is 1 or more results.
Submitting with no results works fine and the page loads correctly.
Submitting with 1 result errors out with
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
Submitting with 10 results errors out with:
java.lang.IndexOutOfBoundsException: Index: 2, Size: 0
Submitting with 100 results errors with :
java.lang.IndexOutOfBoundsException: Index: 6, Size: 0
Submitting with 200 results errors with :
java.lang.IndexOutOfBoundsException: Index: 155, Size: 0
The number seems to be random (I am guessing it is how far into the
form it gets before the error is encountered)
Any help on this would be much appreciated.
I am including all the information that I believe to be important but
would have no problem including more.
In the jsp form there is:
<html:form action="/skuSearch" method="post" >
<center>
<table width="400" border="1" align="center" cellpadding="0"
cellspacing="0">
<tr>
<td>
<table border="0" cellspacing="1" cellpadding="1"
width="100%" >
<tr align="center">
<td><html:text
property="searchString" size="30"
maxlength="30"/></td>
<td><html:submit>Search</html:submit></td>
</tr>
<tr><td colspan="2"></td></tr>
</table>
</td>
</tr>
</table>
</center>
</html:form>
<html:form action="/searchResults" method="post" >
<center><p><html:submit>Add To Order</html:submit></p></center>
<table align ="center" width="90%" border=1>
<tr>
<td> Product </td>
<td> Product Desc </td>
<td> Quantity </td>
</tr>
<logic:notEmpty name="SkuSearchForm" property="results">
<logic:iterate name="SkuSearchForm" property="results" id="results">
<tr>
<td> <bean:write name="results" property="product" />
</td>
<td> <bean:write name="results" property="description" />
</td>
<td> <html:text name="results" property="numProducts"
indexed="true" /> </td>
</tr>
</logic:iterate>
</logic:notEmpty>
<logic:empty name="SkuSearchForm" property="results">
<tr><td colspan="3" align="center">NO RESULTS</td></tr>
</logic:empty>
</table>
</html:form>
In the action (this action is only for the search results):
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
Exception
{
SkuSearchForm skuform = (SkuSearchForm) form;
HttpSession session = request.getSession();
User user = new User();
Order order = new Order();
ArrayList products = new ArrayList();
ArrayList results = new ArrayList();
user = (User)session.getAttribute("User");
order = user.getOrder(user.getCurrOrder());
products = order.getProducts();
int number = 0;
int count = 0;
Iterator iter = results.iterator();
//there is nothing happening in here as there is no results for some reason.
while(iter.hasNext())
{
Product p = (Product) iter.next();
if(p.getNumProducts() != 0 )
{
products.add(p);
}
count++;
}
{
count = 1;
Product p = new Product("TestProd " + count,
"TestDesc"+count + "
" +count, 10, new BigDecimal("101.0"));
products.add(p);
results.add(p);
count++;
}
order.setProducts(products);
order.setOrderId("ID12");
user.changeOrder(order, "ID12");
skuform.setResults(results);
return mapping.findForward("success");
}
In the form (The methods I thought were appropriate):
public void setResults(ArrayList results)
{
this.results=results;
}
public ArrayList getResults()
{
return this.results;
}
public Product getResult(int index)
{
if(this.results == null)
{
this.results = new ArrayList();
}
while(index>= this.results.size())
{
this.results.add(new Product());
}
return (Product)results.get(index);
}
Thanks so much in advance for your time on this matter.
