Re: Setting css of a row
The same way you retrieve any action property. That said, I'm not a fan of mixing layers like that: * possibly* get something business- oriented from the action and use CSS to style it... but a color from the action is poor design.

How to use
Hi All, I am now using tag with simple theme. It shows two select-list fine, but if I click the button to move the items, it doesn't work. Any clue can help me? Now I am trying to write a double-select with JQury & HTML. Thank you in advance. Regards, Mead
Have you ever used InputConfig annotation?
Hello, By looking at DefaultWorkflowInterceptor I saw an annotation that I didn't know existed. I am talking about: com.opensymphony.xwork2.interceptor.annotations.InputConfig I think it can be used for input repopulation and can be used as an alternative to Preparable and . What surprised me was that there is a little documentation about the use of the annotation or examples. Haver you ever used this one before? Is it a good idea to use it for input repopulation for example collections for selects in case a validation fails?

How to pass date from action to custom jsp tag?
Hello, I want to create simple dummy tag.
I have an action:
class MyAction extends ActionSupport{
/** Some code*/
public Department getRoot(){
/** Some code foes here...*/
return departmentInstance;
}
}
a tag:
<%...@tag language="java" pageEncoding="UTF-8" body-content="empty" %><%@
attribute name="tree" required="true"%><%@ taglib
uri="http://java.sun.com/portlet_2_0"; prefix="p"%><%...@tag
import="ejb.model.Department"%><%
Object attrTree = pageContext.getAttribute("tree");
System.out.println("TreeTagHelper->tree=["+attrTree+"]");
if(attrTree!=null){
System.out.println("TreeTagHelper->tree.class=["+attrTree.getClass().getName()+"]");
}else{
System.out.println("TreeTagHelper->tree.class=[!!NULL!!!]");
}
try{
//some code...
}catch(Exception e){
System.out.println("Error while drawing
tree["+e.getMessage()+"]");
}
%>
and my jsp with tag:
What do I have to do if I want to pass result of MyAction#getRoot to my
dummy tag?
I've tried to these:
Nothing happens, i tag I get String with value "root" or get null.
I can't pass an object to tag attribute...
What do I do wrong?

Just one namespace for /barspace/myspace. It's not like a directory structure on a file system. So /barspace/myspace/bar.action will look up an action called bar in the namespace /barspace/myspace/.

Re: UpDownSelect & JPA
Thanks guys! String setup was legacy for single select which worked fine. Select is populated with entity list so will re-work form entity to have select list entity as property and go from there.

So I wonder if the web ui are built by some javascript framework for exmaple
the ext -we used to build a form by the exe library:
var form=new *Ext*.*form*.FormPanel({});
And the form are submitted by a ajax request,so how about the s2 tag at this

Re: UpDownSelect & JPA
You should re-shape your DB design IMHO. If you expect multiple values for an entity property why do you declare as a plain string? You should consider to represent as at least an integer array (or even as an entity). 2010/11/5 Nick Broadhurst : > Hi All, > > I am using the struts2 updownselect for getting multiple selections from > user.

Re: how does the namespace work in struts
>> This HTML code, will post your form to the RELATIVE path [space/register]. So, the ABSOLUTE path which is requested will depend on the current URL of this page. If ABSOLUTE path is not right, no doubt struts2 can not map it to a right namespace/action. >> I will get a 404 error if I set the action to "/space/register" This HTML code, will post your form to the ABSOLUTE path [/space/register]. But your web app is running under the [context path]. So the valid URL should be something like [/contextPath/space/register.action] My suggestion is: (1)Use the Struts2 tag lib, get it works.

Re: how does the namespace work in struts

how does the namespace work in struts
I meet some problem when I try to learn the namespace of struts2,I am using struts-2.2.1. After read the docs at: http://struts.apache.org/2.2.1/docs/namespace-configuration.html I am confused for the following reason: The example: greeting.jsp bar1.jsp moo.jsp bar2.jsp This is the explanation: *If a request is made to /barspace/foo.action, the namespace /barspace will be checked for action foo. If a local action is not found, the default namespace is checked. In the Namespace Example, there is no action foo in the namespace /barspace, therefore the default will be checked and /foo.action will be executed.* I wonder why it is '/foo.action' rather than 'foo.action",it said that it will find the foo.action at the default namespace,and the default namespace is "",so it should be foo.action,why there is a '/'?? ALso problem 2: *Namespace are not hierarchical like a file system path. There is one namespace level. For example if the URL /barspace/myspace/bar.action is requested, the framework will first look for namespace /barspace/myspace.* For the request url "/barspace/myspace/bar.action", the '/barspace/myspace' will be splitted as a namespace,so what is the action now? is it the "/bar.action" or "bar.action",since the "/" may stand for a root namespace. I am really confused,anyone can give me a detailed suggestion?? so I do some test: This is the struture of my test project: Struts_TestProject WebContent js(floder) jsp() reg.jsp thank.jsp WEB-INF web.xml lib() index.jsp 1)Default namespace test First I did not define the namespace in the struts.xml: /jsp/thank.jsp This is the HTML form(I am not intend to use the tag now): It works well, the page will jump to thank.jsp,the only problem is I have not found any way to pass some parameters to the thank.jsp and render them in the page.However this is not the main problem, I think I will make it clear oneday. 2)set a namespace Then I tried to test the namespace, I add a namespace to the package: ...Other configuration are same as it in the above. Then I call it by this manner: Then the struts show me the exception: **There is no Action mapped for action name register** (The following parameter is I get from debugging step by step at the IDE :(:( String servletPath = request.getServletPath()=== /jsp/space/register String requestUri = request.getRequestURI() /Struts_Test/jsp/space/register Then the "/jsp/space/register" is used to parsed the namespace and action name,at last the namespace is set to "" since there is not a mached namespace named "/jsp/space".And the name is set to "register". Obviously, it is wrong. Since the brower add the "jsp" prefix in the action. ) To avoid the browser add a "jsp" prefix in the action, I tried to set the action in form like: The exception is the same as before. Then I se the namespace from "space" to "/space",I also get the same excetpion as before if I use the action to "space/register" in the HTML form,however I will get a 404 error if I set the action to "/space/register". I am crazying!!! How the hell does the namespace work BTW, how does the "result" element in the "action" location the page?That's to say ,for exmaple /jsp/thank.jsp how to locat the thank.jsp? Is it based the base path of the web context? Is the first "/" required?
