Do you have to issue code after the call here:
frm.set("typeName", "xxxxx");
like:
placeFormBackInScope( mapping, frm, request );
which would place the updated form back in scope:
public void placeFormInScope(ActionMapping mapping,
ActionForm form,
HttpServletRequest request) {
if (mapping.getScope().equalsIgnoreCase("REQUEST") ) {
request.setAttribute( mapping.getName(), frm );
} else if ( mapping.getScope().equalsIgnoreCase("SESSION")) {
HttpSession session = request.getSession();
session.setAttribute( mapping.getName(), frm );
}
}

Subject: form-property value set in dispatch action is lost
In struts config have a Dynavalidator form-bean
<form-bean name="Form1" type=".... DynaValidatorForm">
<form-property name="typeName" type="java.lang.String"/>
......
</form-bean>
have prepare(Action) and dispath(LookupDispatchAction) actions for the jsp
in the config which are session scoped.
<action
path="/PrepareAction"
type="com.PrepareAction"
name="Form1"
scope="session">
<forward name="success" path="/pages/Accounts.jsp"
redirect="false"/>
</action>
<action
path="/DispatchAction"
type="com.DispatchAction"
name="Form1"
scope="session"
parameter="method">
<forward name="successCalc" path="/PrepareAction.do"
redirect="false"/>
</action>
In the jsp have a submit button which dispatches to the dispatch action to
one of the methods in it.
I am setting one of the form property value in that method.
public class DispatchAction extends LookupDispatchAction {
protected Map getKeyMethodMap() {
Map map = new HashMap();
map.put("btn.calc", "calc");
}
public ActionForward calculate(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
DynaValidatorForm frm = (DynaValidatorForm)form;
frm.set("typeName", "xxxxx");
return mapping.findForward("successCalc");
}
}
setting the form-property value in the dispatch action i.e the "typeName" to
"xxxxx"
When it is sucess it is going back to the prepare action and the form
property value is "" instead of "xxxxx". checked at the first statement in
the execute method in prepare action the form-property value is different.
not sure why the form-property value is different in prepare action as
before. When in dispatch action the form-bean had the right value i.e the
form-property in form-bean to "xxxxx". but when came to prepare it's value
is lost.
why is this happenning? how can this be fixed?
Thanks.
