Hi Mark, By doing valueStack.getContext(); we get the valueStack's context (a Map) whose value with "someKey" as its key is accessible through <@s.property value="%{#someKey}" />
There's a root in the value stack as well, valueStack.getRoot(); which is like a stack, I think that's where the action resides. rgds Mark Menard <[EMAIL PROTECTED]> wrote: Is there a means of examining the value stack. I have a very strange situation where OGNL in my JSP is returning a value from com.opensymphony.xwork2.ActionContext.parameters on the stack, even though I have a property with the name on my action class. It's almost like OGNL is skipping over the property of my action and moving down the stack until it find my property sitting in the "parameters" Map. I'd like to be able to dump the stack from top to bottom, listing the names of the object in the stack, and call toString() and getClass().getName() on them. I tried the following in an Interceptor using PreResultListener: valueStackContext = context.getValueStack().getContext (); for (Object o : valueStackContext.keySet () ) { if (o == null) { System.out.println ("o is null!!!!!!!!!!!!!!!!"); } else { Object value = valueStackContext.get (o); System.out.println (o.toString() + ": " + (value == null ? "null" : value.toString () ) ); System.out.println (o.toString() + ": " + (value == null ? "null" : value.getClass().getName () ) ); } } But, I don't see my action on the stack. Stripping out the toString() output I see the following: 17:35:27,773 INFO [STDOUT] last.bean.accessed: null 17:35:27,773 INFO [STDOUT] struts.actionMapping: org.apache.struts2.dispatcher.mapper.ActionMapping 17:35:27,773 INFO [STDOUT] com.opensymphony.xwork2.ActionContext.locale: java.util.Locale 17:35:27,773 INFO [STDOUT] session: org.apache.struts2.dispatcher.SessionMap 17:35:27,773 INFO [STDOUT] current.property.path: null 17:35:27,773 INFO [STDOUT] attr: org.apache.struts2.util.AttributeMap 17:35:27,773 INFO [STDOUT] com.opensymphony.xwork2.ActionContext.application: org.apache.struts2.dispatcher.ApplicationMap 17:35:27,773 INFO [STDOUT] report.conversion.errors: java.lang.Boolean 17:35:27,773 INFO [STDOUT] com.opensymphony.xwork2.ActionContext.actionInvocation: com.opensymphony.xwork2.DefaultActionInvocation 17:35:27,773 INFO [STDOUT] last.property.accessed: null 17:35:27,774 INFO [STDOUT] com.opensymphony.xwork2.ActionContext.session: org.apache.struts2.dispatcher.SessionMap 17:35:27,774 INFO [STDOUT] application: org.apache.struts2.dispatcher.ApplicationMap 17:35:27,774 INFO [STDOUT] com.opensymphony.xwork2.ActionContext.parameters: java.util.HashMap 17:35:27,774 INFO [STDOUT] parameters: java.util.HashMap 17:35:27,774 INFO [STDOUT] com.opensymphony.xwork2.ActionContext.name: java.lang.String 17:35:27,774 INFO [STDOUT] __link: [Ljava.lang.Object; 17:35:27,774 INFO [STDOUT] com.opensymphony.xwork2.util.ValueStack.ValueStack: com.opensymphony.xwork2.util.OgnlValueStack 17:35:27,774 INFO [STDOUT] xwork.MethodAccessor.denyMethodExecution: java.lang.Boolean 17:35:27,774 INFO [STDOUT] com.opensymphony.xwork2.dispatcher.HttpServletRequest: org.apache.struts2.dispatcher.StrutsRequestWrapper 17:35:27,774 INFO [STDOUT] xwork.NullHandler.createNullObjects: java.lang.Boolean 17:35:27,774 INFO [STDOUT] com.opensymphony.xwork2.ActionContext.conversionErrors: java.util.HashMap 17:35:27,774 INFO [STDOUT] com.opensymphony.xwork2.dispatcher.ServletContext: org.apache.catalina.core.ApplicationContextFacade 17:35:27,774 INFO [STDOUT] com.opensymphony.xwork2.dispatcher.HttpServletResponse: com.opensymphony.module.sitemesh.filter.PageResponseWrapper 17:35:27,774 INFO [STDOUT] request: org.apache.struts2.dispatcher.RequestMap I don't see an instance of my action class, nor an ActionProxy.
