I am working with struts 1.2.9 and trying to use the iterate function. I
seem to be having a problem extracting the value from a text field inside an
iterated loop. I am able to get/set values thare are being placed simply
into html, but run into difficulties when working with the text fields. I
am able to set the values into the text field, but unable to pull them out
when in the action code of the form. The following is what I have used for
code thus far:
If I understand the struts wiki page that I was pointed to properly the name
in the text must be the same as the id, but when I would try that I would
simply receive index out of bounds errors - that was making all references
to counter called results.
Results is an object that is holding a product, description, and
numProducts.
<logic:notEmpty name="ProdSelectionForm" property="results">
<logic:iterate name="ProdSelectionForm" property="results" id="counter">
<tr>
<td> <bean:write name="counter" property="product" />
</td>
<td> <bean:write name="counter" property="description" />
</td>
<td> <html:text name="counter" property="numProducts"
indexed="true" size="15" maxlength="15"/> </td>
</tr>
</logic:iterate>
</logic:notEmpty>
This is in the Action portion - well it is a snippet of the entire thing.
ProdSelectionForm prodSelection = (ProdSelectionForm) form;
int count = 0;
// take in the number of items in the order ArrayList and iterate through
them
while(count < order.getProductsSize() )
{
Product p = null;
// pull the product from the order at each position to manipulate them.
p = (Product) products.get(count);
// set the order amount to be what the old amount was on top of the
amount that is currently on the screen
p.setNumProducts(p.getNumProducts() + 1 + prodSelection.getNumProducts
());
// the below code was to test and see if the variable would change at
all, with the +100 it would increment the amount on the screen by 100
everytime the action was called, so that lead me to believe that I am
setting the values right.
//p.getNumProducts() + 100 + prodSelection.getNumProducts() );
// set the product back into the product arraylist so it can be passed
to the
products.set(count, p);
count++;
}
//set the product arrayList back into order so it can be presented on the
screen.
order.setProducts(products);
And finally for the form I have the following relevant code:
/**
* @return Returns the numProduct.
*/
public int getNumProducts() {
return numProducts;
}
/**
* @return ReturnsnumProduct at the specified index
*/
public int getNumProducts(int index) {
Product p = (Product) results.get(index);
return p.getNumProducts();
}
/**
* @param numProducts The numProduct to set.
*/
public void setNumProducts(int numProducts) {
this.numProducts = numProducts;
}
I seem to be able to pull the value from the page, but it won't pull the
changed values - that is to say it will only pull the value that was there
when the page was first presented regardless of anything that I type.
Could someone point me to where I am having a brain fart. Ps. I have been
made aware that I should be using JSTL, but would welcome any other critisms
the list might have to offer.
thanks in advance for your time on this matter.
