Hi all
I have a very annoying problem with removing a form bean:
I'm working with WSAD v6.0 (RAD v6.0) and struts v1.2.4
When creating a new Item I call EditItemAction (mehod create)
The ItemForm is created and then passed to editItem.jsp
>From there it arrives to SaveItemAction (method create)
and if the item was successfully saved it is returned with a success
message to EditItemAction (method create) - to enable the user to create
another item.
The problem is that when I get to the input form the second time - it
still shows the data of the first Item that was created before, i.e. the
form bean is not removed.
The scope in the struts-config is request and I also checked by printing
mapping.getScope() which was also request.
There is no such attribute in the session scope - I checked that.
I saw that after doing -
request.removeAttribute(mapping.getAttribute()); - the attribute (i.e.
the form) was is actually removed, but when it is forwarded to the
EditAction to create another new Item - it somehow finds the previous
form bean.
here's the relevant code from struts-config file:
<action path="/EditMsvItem"
type="org.nite.mashovweb.actions.EditMsvItemAction"
name="MsvItemForm"
scope="request"
validate="false"
parameter="action">
<forward name="success" path="/editMsvItem.jsp">
</forward>
<forward name="failure" path="/Error.jsp">
</forward>
</action>
<action path="/SaveMsvItem"
type="org.nite.mashovweb.actions.SaveMsvItemAction"
name="MsvItemForm"
scope="request"
input="/editMsvItem.jsp"
parameter="action">
<forward name="search" path="SearchMsvItem.do">
</forward>
<forward name="update_failure" path="/editMsvItem.jsp">
</forward>
<forward name="last_search_results"
path="SearchMsvItem.do?action=lastPage">
</forward>
<forward name="create_success" path="EditMsvItem.do?action=create">
</forward>
</action>
Also here's the create methods in SaveItemAction and in EditItemAction:
In SaveItemAction:
public ActionForward create(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
HttpSession session = request.getSession();
MsvItemForm subform = (MsvItemForm) form;
MsvItemTO newItem = new MsvItemTO();
if (isCancelled(request)) {
request.removeAttribute(mapping.getAttribute());
return (mapping.findForward("item_main_menu"));
}
try {
PropertyUtils.copyProperties(newItem, subform);
} catch (Throwable t) {
log.error("populate bean error", t);
throw new ServletException("populate bean error", t);
}
try {
MsvItemOperHome msvItemOperHome =
(MsvItemOperHome)ServiceLocator.getInstance().getRemoteHome("ejb/mashov/
MsvItemOperHome",MsvItemOperHome.class);
MsvItemOper msvItemOper = msvItemOperHome.create();
msvItemOper.createNewItem(newItem);
} catch (Exception e) {
log.error("insert error", e);
throw new ServletException("create item failed", e);
}
request.setAttribute("ErrorMessageKey","error.update.record.nochange");
request.removeAttribute(mapping.getAttribute());
session.removeAttribute(mapping.getAttribute()); //did not help
form.reset(mapping, request); //Duram - did not help
return (mapping.findForward("create_success"));
}
In EditItemAction:
public ActionForward create(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
MsvItemForm subform = (MsvItemForm) form;
//subform.reset(mapping, request); //needs checking
subform.setAction("create");
return (mapping.findForward("success"));
}
I really really need help with this one
Thanks
