Textfield problem with pulling value out.
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.

Re: Textfield problem with pulling value out.
Posted by Adam K <ad...@gmail.com>.
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.

Re: Textfield problem with pulling value out.
Posted by Adam K <ad...@gmail.com>.
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.

Re: Textfield problem with pulling value out.
Posted by Adam K <ad...@gmail.com>.
One other thing I just realized that I should include is the fact that all
of my forms are request based, which doesn't allow me to include the form
information from one to the next, so to get around that (for more testing) I
have included the array in a Session variable so that I can pull it out in
the second action.
Again thanks for all thoughts/ideas/suggestions

Re: Textfield problem with pulling value out.
Posted by Adam K <ad...@gmail.com>.
If this is a bad technique I would be more than happy to change it to a more
standard technique. Any suggestions on how to improve my code are always
welcome.
thanks for the suggestions thus far.

Re: Textfield problem with pulling value out.
Posted by Chris Pratt <th...@gmail.com>.
I don't think I've ever seen that technique before, but you have to remember
that size() is 1 based and index (or get(index) ) is 0 based. So when
someone calls getNumProducts(5), your while loop fills in indexes 0, 1, 2,
3, and 4 (because then index and this.results.size() are both 5), then you
proceed to ask for results.get(5), which doesn't exist. You should be able
to change your while list to something like:
while(index >= this.results.size() + 1) {
this.results.add(new Product());
}

Re: Textfield problem with pulling value out.
Posted by Adam K <ad...@gmail.com>.
Here are the 2 get methods that I have.
thanks again for all the help.
public int getNumProducts() {
return numProducts;
}
public int getNumProducts(int index)
{
if(this.results== null)
{
this.results = new ArrayList();
}
while(index >= this.results.size())
{
this.results.add(new Product());
}
Product p = (Product) results.get(index);
return p.getNumProducts();
}
