Iterate tag update
Hi, I am using logic:iterate tag as follows to print a table with text boxes. logic:iterate id=product name=productSearchForm property=productList tr td align=left bean:write name=product property=productNumber filter=true/ /td td align=center html:text name=product property=quantity size=3/ /td /tr /logic:iterate I have a array of objets(Product) in productList. When I update the quantity and submit the page, it does not update the information into the productList. What might be the problem??? Vaibhav
Re: Iterate tag update
Do u have setter methods in the Product class like - setQuantity(int qty)
???
Also U need to have indexed iterate tag written by Dave Hey . So u can use
html:text name=product property=quantity size=3 index= true/
Here is the ActionForm
public Product [ ] getProductList( ) {
return this.productList;
}
public setProductList(Product [ ] productList) {
this.productList = productList ;
}
public Product getProductList(int index) {
return (Product)productList[index];
}
Remember have proper setter methods in the Product class like setQuantity
int qty )

RE: Iterate tag update
When I give the index=true attribute, it gives me following error
Attribute index invalid according to the specified TLD

Re: Iterate tag update
The problem is, the generated names of the HTML form elements do not
correspond to the names of properties of your ActionForm.
Here a sample, how this can be done:
logic:iterate name=myForm property=elements id=element indexId=i
type=de.grayman.test.struts.MyElement
tr
td
html:checkbox property='%= element[ + i + ].member %' /
html:hidden property='%= element[ + i + ].elementName %' /
/td
tdbean:write name=element property=elementName //td
tdbean:write name=element property=elementDescription //td
/tr
/logic:iterate
In the MyForm class, there have to be two properties (getter methods):
1) the collection elements
2) indexed property element
private Vector elements;
public Collection getElements() {
return this.elements;
}
public MyElement getElement(int i) {
while (getGroups().size() = i) {
this.element.add(new MyElement());
}
return (MyElement) this.elements.get(i);
}
Note: Class MyElement has read/write properties member, elementName,
elementDescription, ...
Note: The getElement(int i) fills the Vector with empty elements, if they do
not exist.
In this way, the form will be filled correcly from the submitted HTML-Form. Of
course,
you could use another approach, e.h. HashTable or an Array instead of Vector.

Re: Iterate tag update?
* Martin Cooper [EMAIL PROTECTED] 2001-06-13 (21:42:47): I just checked in a change to the iterate tag which allows you to access the current index as a scripting variable. If you specify the 'indexId' attribute, a scripting variable with the specified name will contain the current index (as an Integer) on each iteration. This will be available in the 6/14 nightly build, and also in Struts 1.0. i think this is exactly what i needed recently..after all i cannot follow 100percently right now. would be great if you can post a snippet where you do such a iteration and use this feature. thx alot. - fw -- \|/ \|/ --([EMAIL PROTECTED])- @~/ ,. \~@ /_( \__/ )_\ waste of money, brains and time - wombat() \/ -

Martin, Could you please give an example of how it can be used? I just did the index naming the old fashioned way(i.e., adding index to the property string) and would like to replace it.
