Re: Checkboxes problem
Sharad, thank you for the answer. Keeping in mind what you said, I tried to make it work like this: This populates the checkboxes, but when I submit the data, all I can get is ArrayList of true booleans: [true, true...], and I can not use that. I need something like: [x]Tom [ ]Dick [x]Harry And after submit, the list should be: [Tom, Harry]. The problem is that I can not make checkbox return String value instead of boolean. There must be a way to do so, because s:checkboxlist can return ArrayList, but I don't know how to do so by using s:checkbox.

[S2] datepicker default value in 2.1
Hi, I don't know if I can post here a question about version 2.1 but ... I do :) I have downloaded and compiled (from svn) the version 2.1 of Struts2. My question is: is it possible to set the default value of a datepicker field so that when i make a mistake filling the field it don't change the value to 01/01/1970? For example, when I write "22/04/2007u" then the value is changed to "01/01/1970", but I would like to leave the wrong value and to validate it at the submit of the post (like YUI ^_^ ).

Re: Checkboxes problem
or Any of this should solve your problem. first one will iterate for itself second we are doing that. But still all checkbox shouldhave same name.

Populate s:select using Hasttable
I am trying to populate a s:select using a Hashtable.
<% customer.getCustomersForUser(sessionObject.getUserName()); %>
The customer.getCustomersForUser() method populates a Hashtable called
customerList which has the appropiate get and set.
I assumed that calling customer.customerList in the 'list' attribute
would call the customer.getCustomerList which would return the
Hashtable.
When I try to execute the code I get the following error:
org.apache.jasper.JasperException: tag 'select', field 'list': The
requested list key 'customer.customerList' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]
org.apache.struts2.components.Component.fieldError(Component.java:231)
org.apache.struts2.components.Component.findValue(Component.java:293)
org.apache.struts2.components.ListUIBean.evaluateExtraParams(ListUIBean.java:79)
.
.
.
I verified that the Hashtable is getting populated with data. Is
there anything I am missing that needs to tell the select that I am
using a Hashtable?
Thank you,
Rich

Hello excuse me but this code is ok. But if the UserViewAction implements
ModelDriven so it implement the method:
@Override
public User getModel() {
return getUser();
}
And the jsp page become:
User:
Username:
Roles:
-
The jsp page don't display anything? why? if the action is a modelDriven
this jsp page have to e correct!
Thanks

Interceptors
I am new to struts and I am trying to write an interceptor. I have the interceptor set up so it runs on every action (except one). The interceptor checks the users session to make sure it has not timed out. If the session is after timing out I want to create a new session and add some values to the an object we keep in session and redirect them to the main page of our application. I assumed if the interceptor found that the session was expired then I could redirect to a CreateSession action. I have a few questions: Is this a good use for an interceptor? In the struts docs it says: "Just like an action method, intercept returns a result used by Struts to forward the request to another web resource" I know how to call the next interceptor if everything works but how do I call a different action if the session is timed out? Is my logic is ok? Thank you, Rich - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Problem with s:action

The result of this action redirect to a jsp that contains a combobox populated with a iterator.

And has also one more thing that i dont understand, the param that I pass in s:action dont came setup it`s always null.

Re: Best Practice pass data into an included jsp
I tried using s:include with nested s:param tags, but could not read the
parameters using the s:property tag at all. The only way that I could read
the parameter was by using:
<%= "param1:" + request.getParameter("param1") %>
as suggested in:
http://www.nabble.com/struts2-how-to-access-a-param-s%3Ainclude-tf2871075.html
I've had success with the following strategy (adapted to your example):
File: callPassRow.jsp
">
...
File: Random jsp's
This feels like a Tiles-like strategy to me -- which is actually how I'm
using it:
pageToBeDisplayed.jsp:
template.jsp:
Some text
so that includes/tile1.jsp gets included in template.jsp which is used to
make pageToBeDisplayed.jsp
It may not be the speediest operation, but it does provide flexibility.
Hope this helps...

Action tag with parameters
When directly calling an action we can send a petition like .../ActionName.action?var1=val1&var2=val2 using the GET method. I understand that that calls an action with a couple of parameters. Can I do something similar when calling an action from the tag ? that is, Can I call an action using the action tag with a couple of parameters? If possible, can it also be done using the POST method? Thanks in advance, Asaf - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

You might look into the Tiles project (http://tiles.apache.org), that's

[S2] App produces lot garbage IMPORTANT NEWS (I HOPE)
Hi, for the readers of my previous messages I'm still facing the problem. After having upgraded the application server and even re-designed some code to not use JMS to exclude some possible causes now I think I've found something interesting. And it's struts related. I've keeped some threads dump of when the server continually allocate and garbage collect large amount of data. Today I take seven of them. Looking carefully to all of them I noticed there is ALWAYS the same http thread that's on the struts tag handler on a specific jsp page. This page is used about one hundred times a day. But when the server is generating garbage there is always a thread in it. Moreover I trace the visits on a sql database so I'm sure that the thread is somewhat "locked" into that page and it's not many different visits to the same page. Below you'll find the threads dump taken a few seconds one after the other, in a moment when the server is producing garbage. I'm not a thread dump expert reader but it seems to me that's some infinite loop that starts on org/apache/struts2/views/jsp/ ComponentTagSupport.doEndTag(ComponentTagSupport.java:43) The jsp source is at http://www.andreavettori.com/trace/ carrelloB_jsp.java This page is "special" because there are TWO struts forms (with different name) both with a textfield and a password field, with the same name in the two forms. Both point to the same action class with different action name in struts.conf. Not sure if this is peculiar or not. I'll try to read the sources of the various methods called in the thread dump but I hope that someone more expert on the struts source code can help me found IF this is the source of my problems. P.S. I'm using the simple template.

Thanks. I have a better understanding now. By number 3 I meant, how do I reference the action, but I realized this is done when I create the action in struts.xml. I was confused about #6. I didn't know if I could use a Java object or not. ie. I thought I had to build the OGNL list expression string and pass it back. With #7/#8. If petsDao.pets is an ArrayList does listKey="fieldName" and listValue="fieldName2" mean that to get these values, call getFieldName() getFieldName2() on the objects stored in the ArrayList? IF so, do I need to use generics so it knows what object to expect? I have one other question: If I have a Hashtable with the following data: 1,"One" 2,"Two" 11,"Eleven" Is it possible to make the select box display the data sorting by id or sorting by value? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [S2] App produces lot garbage IMPORTANT NEWS (I HOPE)
All the traces points me to this function on the xwork library
Since it contains an infinte loop it's promising ;)
Need to sleep now, I hope tomorrow to find someone else solution in
my inbox :)
Thank you
public static Object translateVariables(char open, String
expression, ValueStack stack, Class asType, ParsedValueEvaluator
evaluator) {
// deal with the "pure" expressions first!
//expression = expression.trim();
Object result = expression;
while (true) {
int start = expression.indexOf(open + "{");
int length = expression.length();
int x = start + 2;
int end;
char c;
int count = 1;
while (start != -1 && x < length && count != 0) {
c = expression.charAt(x++);
if (c == '{') {
count++;
} else if (c == '}') {
count--;
}
}
end = x - 1;
if ((start != -1) && (end != -1) && (count == 0)) {
String var = expression.substring(start + 2, end);
Object o = stack.findValue(var, asType);
if (evaluator != null) {
o = evaluator.evaluate(o);
}
String left = expression.substring(0, start);
String right = expression.substring(end + 1);
if (o != null) {
if (TextUtils.stringSet(left)) {
result = left + o;
} else {
result = o;
}
if (TextUtils.stringSet(right)) {

}
expression = left + o + right;
} else {
// the variable doesn't exist, so don't display
anything
result = left + right;
expression = left + right;
}
} else {
break;

[S2] FreeMarker sample application
Good Day, I have been using FreeMarker for the S2 plug-in development and some other projects. I find the FTL language more expressive than JSP and I was wondering if there is a sample S2 application that makes use of FTL for the views.

[S2] Default Action
I am trying to figure out how to set the default class that is executed when a class is not specified on an declaration. When you specify something like: /home.jsp Struts automatically runs com.opensymphony.xwork2.ActionSupport. But I am trying to figure out how to accomplish this: user /home.jsp Since ActionSupport doesn't have a setRole method, this won't work out of the box, so I created a simple extension of ActionSupport to hold the role value. After a bit of googling, I got the idea that this should work: but that doesn't seem to do the job. Is it possible? Is there another way to specify this type of information on a per Action basis? Any insights would be appreciated. (*Chris*)
