oh yes, this does the trick! Thanks!

I just found another problem when using xml based validation. In struts1, there is a page attribute, which can tell the validator to validate certain fields which belong to that page, but this useful feature is not in struts2, is there any replacement for that?

I occasionally have to do validation in the execute() method but always
prefer to do declarative validation with annotations wherever possible since
it is so much simpler and cleaner. This means all my actions have to be able
to handle an 'input' result. Since 'input' result is the standard for
validation errors you should be prepared for it as the next programmer who
works on your code may add a validation() method or add validation
annotations.

@OP: If you know which page# in a wizard sequence to return to and use that
page# in the jsp name then you can make that page# available with a
getPage() method and do this:

  <result name="input">/xxx/MyWizardPage${page}.jsp</result>

It does mean you would need to have a jsp page naming convention that
includes the page#.

check your web.xml to see if your filtering thru SiteMesh e.g.
  <filter>
    <filter-name>sitemesh</filter-name>
    <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>sitemesh</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

where com.opensymphony.module.sitemesh.filter.PageFilter contains parsePage method
protected com.opensymphony.module.sitemesh.Page
parsePage(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws IOException, ServletException
{
    try
    {
       PageResponseWrapper pageResponse = new PageResponseWrapper(response, factory);
       chain.doFilter(request, pageResponse);
       // check if another servlet or filter put a page object to the request
       Page result = (Page)request.getAttribute(PAGE);
//MG: THIS IS the page you want

       if (result == null) {
          // parse the page
          result = pageResponse.getPage();
       }
       request.setAttribute(USING_STREAM, new Boolean(pageResponse.isUsingStream()));
       return result;
    }

//once you have the Page you can do page.getTitle() and then
//map Title to Page Number
//the other way is to modify protected com.opensymphony.module.sitemesh.Page
//for accessor and mutator for pageNumber

did you ask wes?

Have you try to put lists in lists???

may be it works...

another way can be if you put every item as a s:optgroup

web.xml configuration for Spring
/* The ContextLoaderListener listener should be registered after
Log4jConfigListener
in web.xml, if the latter is used.
*/
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

once thats configured you'll want to use MethodInvokingFactoryBean for FactoryBean which returns a value which is the result of a static or instance
method invocation

http://static.springsource.org/spring/docs/1.2.x/api/org/springframework/beans/factory/config/MethodInvokingFactoryBean.html

as mentioned singleton="true" assures you will load,instantiate and store a cached bean

static factory methods:
An example (in an XML based bean factory definition) of a bean definition
which uses this class to call a STATIC factory method:
<bean id="myObject" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
 <property name="staticMethod"><value>com.whatever.MyClassFactory.getInstance</value></property>
</bean>

<!-- this example will acquire a (target) instance specific version of System defined (version) property -->
<bean id="sysProps" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
 <property name="targetClass"><value>java.lang.System</value></property>
 <property name="targetMethod"><value>getProperties</value></property>
</bean>
<bean id="javaVersion" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
 <property name="targetObject"><ref local="sysProps"/></property>
 <property name="targetMethod"><value>getProperty</value></property>
 <property name="arguments">
  <list>
    <value>java.version</value>
  </list>
 </property>
</bean>Since your question addresses GarbageCollection it would be good to know the difference
between Spring's Beans loader between ApplicationContext (a load class which implements ApplicationContextAware) and BeanFactory (a class which implements BeanFactoryAware)
BeanFactory:
1a)Container locates beans definition (usually derivation of *beans.xml)
1b)Container Loads beans into Container
2)is instantiated LATER with getBean() method

ApplicationContext:
1a)Container locates beans definition depeding on invoking class
-ClassPathXMLApplicationContext-Loads XML from Classpath
-FileSystemXMLApplicationContext-Loads context from XML file in filesystem
-XMLWebApplicationContext-Loads Context from XML(beans.xml/ApplicationContext.xml) contained with webApplication
1b)Container loads and instantiates all beans into Container

so if you see alot of GC activity from jheap or J2EE Server logs you will probably want to consider using BeanFactoryAware implementor class instead of default ApplicationContextAware implementor class

hope this helps

Hi all,
translating portion of old code which was using S1 and Tiles and
ran into problem.

There is one tile representing form which is being used on almost all screens.
One doesn't want to write same tile over and over again since only name
of the action differs.

Existing code used this:

// define name of the action to be a passed from parent tile
<tiles:useAttribute name="formAction" />

then it was used like this:

<html:form action="<%= formAction.toString() %>" ......


I've changed this to use S2 tags:

<s:form action="<%= formAction.toString() %>" .........

and jsp compilers complains:


JSPG0227E: Exception caught while translating /layout/formLayout.jsp:
/layout/formLayout.jsp(11,1) --> JSPG0124E: Custom tag attribute action
cannot be runtime expression. value: "[%= formAction.toString() %]"

Any ideas how to solve it?

Thanks,

Peter.

I have a very simple radio tag like following
<s:radio label="correctOption" name="correctAnswer" id="correctOption"
list=" #{'1':'1','2':'2','3':'3','4':'4'}"
value="questionVo.correctAnswer"/>

questionVo.correctAnswer returns 2. So I want the second radio button to be
preselected but it is not happening. I even tried:

<s:radio label="correctOption" name="correctAnswer" id="correctOption"
list=" #{'1':'1','2':'2','3':'3','4':'4'}" value="%{1}"/>

but that does not work either.

what am I doing wrong?
