Re: Where are my ActionForm's changes?
I removed name and type attributes from my html:form tag. I
also changed the name of the form in action-mappings but still the
same problem. Is there a bug in Struts that the nested tags don't
work with objects?
Thanks,
Marwan

Get rid of the 'name' and 'type' attributes from the html:form.
The reasons?
* they are deprecated. See
http://jakarta.apache.org/struts/userGuide/struts-html.html#form
* they are not necessary
* in your case the action mapping is referring to the form-bean
by the name 'myForm' and the html:form's 'name' attribute is
indicating that a form named 'updateOrderForm' be used. These
will result in two instances of the same class. Not what you
want
Hope that helps

Hi Sri,
You got it right.
This is the code from my Action class that checks for the changes
and
forwards the request to the same page again(I tried to forward to a
view-only page(showorderdetails.jsp) for testing purposes and the
changes still were not reflected).
UpdateOrdersAction.java
-
UpdateOrderForm updateOrderForm = (UpdateOrderForm) form;
if (updateOrder.equalsIgnoreCase(action))
{
List parametersList = updateOrderForm.getParameterList();
int size = parametersList.size();
for (int i = 0; i size; i++)
{
OrderDetailModel model = ((UpdateOrderForm) form).getOrderDetail
(i);
logger.debug(Form model is: + model);
}
Iterator iter = parametersList.iterator();
if (logger.isDebugEnabled())
{
while (iter.hasNext())
{
OrderDetailModel orderDetail = (OrderDetailModel)iter.next();
logger.debug(orderDetail.toString());
}
}
logger.debug( Forwarding to 'edit' page);
NDC.pop();
return (mapping.findForward(edit));
// this will take you back to the same page
}
Here is an excerpt from updateorder.jsp:
-
html:form action=updateOrder name=updateOrderForm
type=mypackage.UpdateOrderForm scope=session
html:hidden property=action value=updateOrder /
logic:iterate id=parameter name=updateOrderForm

tdhtml:text name=parameter property=status indexed=true

/html:form
I appreciate your help.

Thanks Sri for the quick reply.
The first of two assumptions you mentioned below are not true but
I
am not sure about the third one: forwarding to an action that is
re- initializing the form.
My ActionForm.reset() is as follows:
public void reset(ActionMapping mapping, HttpServletRequest
request) {
action = null;
}
And here is my action-mapping:
action path=/updateOrder
type=MyAction
name=myForm
scope=session
validate=false
input=/updateorder.jsp
forward name=update
path=/showorderdetails.jsp/
forward name=edit path=/updateorder.jsp/
/action
The reset method does not have any code that initializes the form
parameters so I don't know why this is happening.

Hi,
I am using the login:iterate tag to display a collection of
objects. The objects have attributes that some can
be edited by the user. After the user changes some values and submits
back to the Action class, the values that were changed in the JSP are
not reflected in the form. I know that because I tried to iterate
through the collection and displayed the values retained from both
the ActionForm.reset() and from the Action class. No changes are
retained; only the original values. I am using Struts 1.1-b3.
Here is my ActionForm:
private List parameterList = new ArrayList();
public List getParameterList()
{
return parameterList;
}
public void setParameterList(List parameterList)
{
this.parameterList = parameterList;
}
public MyObject getMyObject(int index)
{
return (MyObject) parameterList.get(index);
}
What's wrong?

Attribute indexed invalid according to the specified TLD
Hi,
I am getting Attribute indexed invalid according to the specified

Here is part of my ActionForm:
private List parameterList = new ArrayList();
public List getParameterList()
{
logger.debug(List size is: + this.parameterList.size());
return parameterList;
}
public void setParameterList(List parameterList)

public OrderDetailModel getOrderDetail(int index)
{
return (OrderDetailModel) parameterList.get(index);
}
Here is the code in my Action where I set the form on the session:
updateOrderForm.setParameterList(orderDetailList);
//orderDetailList is my ArrayList object
session.setAttribute(updateOrderForm, updateOrderForm);
Here is my JSP:
html:form action=updateOrder.do name=updateOrderForm
type=com.academy.ordering.forms.UpdateOrderForm
logic:iterate id=parameter name=updateOrderForm

I looked at the Struts html:text tag description,

that I can use indexed. I am using Struts 1.0.2. I am doing
something wrong?

Re: posting an updated collection back to Action
Hi,
I looked at all your the responses to this thread and then looked at
Ted Husted's Struts Tip #6 - Use an array to capture multiple
parameters to solve my problem.
However, I still have some problems when I submit my changes(even if
I don't change anything).
My ActionForm looks like this:
private String[] orderLineNumber = null;
private String[] quantityShipped = null;
private String[] quantityCancelled = null;
with setters and getters for these attributes. In the ActionForm
constructor there is nothing to initialize the arrays.
After submitting the form, I am trying to access these arrays in the
Action class like this:
String[] lineNumber = (UpdateForm)form.getOrderLineNumber();
and I get a java.lang.NullPointerException on this exact line.
My JSP looks like this:
%List orderDetailList=(List)session.getAttribute(Constants.ORDERS);%
code
form action=updateOrder.do method=post
logic:iterate id=orderDetail name=orderDetailList
tdbean:write name=orderDetail property=orderLineNumber/td
tdhtml:text name=orderDetail property=quantityShipped //td
tdhtml:text name=orderDetailproperty=quantityCancelled//td
/logic:iterate
input type=submit valueUpdate
/form
/code
This is still not working. The lines in the JSP are objects and not
Strings. My JSP is retrieving a collection of these objects to
display in a grid as you see above. Can I have these objects in my
ActionForm instead of defining arrays for each column in the JSP? All
I need to do is retrieve the grid of data from the JSP to my Action
class with one submit button. That's all.
Thanks,
Marwan

You can create indexed properties ( getOrderDetail(int),

You have to back them whatever way you see fit (I've used arrays in
the past
but I had to make sure they were sized propertly on each call). On
your
JSP, the resulting names for your input fields will need to be
indexed:
html:text name=orderDetail property=quantityShipped
[${index}]/ will
work if you are using the EL version of the html taglib. (Although
I'm not
sure the name property has to be specified if you use the html:form

Subject: posting an updated collection back to Action
Hi,
I have a list of line items displayed in a JSP where some of the
attributes can be edited. I would like to capture the updated data
by
the user to return it to my Action class so I can modify my model
accordingly.
Here is my JSP code:
form action=updateOrder.do method=post

logic:iterate id=orderDetail type=OrderDetailModel
collection=%= orderDetailList %
tdhtml:text name=orderDetail
property=quantityShipped//td
/logic:iterate
input type=submit valueUpdate Order
/form
I know my ActionForm class has to have a property called
orderDetailList. But the question is, how will the correct index be
updated since my list can contain many OrderDetailModel's? Should I
add a method in my ActionForm class like getOrderDetailList.get
(index)? Help!!!

j_security_check with LogonAction
Hi, I am trying to use j_security_check Servlet to authenticate users from a login.jsp. However, if I do this, I will not be able to take advantage of LogonAction class where I need to set certain session and request attributes. If I submit the logon form to LogonAction, I can forward the request from LogonAction to j_security_check but the request object will stay there and I can not forward again using mapping.findForward(success) to a different page since the response is already commited at that point. Is there a way to work around this? Marwan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Cannot find bean categoryArray in scope request
Hi, I am using Struts where I have an ShowCategoriesAction that extends Action. In the perform method, I am reading data from the database and storing it in a collecion object(ArrayList). Then I am using request.setAttribute(categoryArray, myCollectionObject) to set it on the request. I have verified that the collection has actual data before forwarding to the JSP. Now, when I call mapping.findForward(success) from the perform method, it forwards the request to a showCategories.jsp page where I use the following Struts tag: code logic:iterate id=category type=myPackage.Category name=categoryArray scope=request html:link page=/showItems.do name=category property=mapping bean:write name=category property=categoryName filter=true/ /html:link /logic:iterate /code I get this error: boldcodeError 500: Cannot find bean categoryArray in scope request /code/bold I even tried to put the object on the session and the application and look it up in the iterate tag and still the same problem. I tried to print the attributes on the request object from the JSP and it did show the categoryArray object there. But apparantly it was null. Can anyone help me in figuring out what the problem is.
