prepare method not working

Hi,

I am implementing prepare method to populate the values in the list if
validation fails and we need to present the same page back to the user.

Even after implementing the prepare method, I still get the same error as
before and when I debug with eclipse, i never enter into prepare method. I
am using basic struts-default stack and in this stack, prepare comes before
validation.

Is there anything else that I need to do to get prepare method working like
specifically implementing preparable interface.

Attached are the code snippets.
<struts>
	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<constant name="struts.devMode" value="false" />
	<constant name="struts.objectFactory"
		value="org.apache.struts2.spring.StrutsSpringObjectFactory" />


	<package name="ESG" namespace="/ESG_TPMS" extends="struts-default">
         <action name="AddTestAccount" 	class="esg.sc.net.AddTestAccount">
			<result name="input">/WEB-INF/jsp/AddTestAccount.jsp</result>
			<result name="error">/WEB-INF/jsp/AddTestAccount.jsp</result>
         </action>
        <action name="RefreshCompanyList"
class="esg.sc.net.RefreshCompanyList">
			<result>/WEB-INF/jsp/companyList.jsp</result>
			<result name="error">/WEB-INF/jsp/blank.jsp</result>
	</action>

Thanks for your help

You do need to implement the Preparable interface. Otherwise the prepare
interceptor will not be able to call your prepare method.

Chapter 10 of Budi Kurniawan's book Struts 2 Design and Programming has a
good explanation of how to use the prepare interceptor.

It does, but validation != preparable. The preparable interceptor looks 
for implementors of Preparable.

Thanks Dave. It is working after I implemented the Preparable interface

Thank you. As of now I am not implementing Preparable. But I will try
implementing it and see. I thought the order of interceptors in
struts-default package will automatically take precedence and get applied as
validation happens automatically.

Are you, or are you not, implementing Preparable? You need to, AFAIK. Is 
there documentation that suggests otherwise?
