Hello folks
2 days ago I wrote:

the definition of the associated action is (note the scope parameter):
<action path="/canalizzazione_cld"
input="/jsp/pagecontainers/canalizzazioneCLD.jsp" scope="request"
name="canalizzazioneCLDForm" parameter="command"
type="it.ggl.callcenter.presentation.controller.action.CanalizzazioneCLDAction">
<forward name="avanti"
path="/RISS_FRONTOFFICE/container_frontOffice.jsp" /><forward name="indietro"
path="/jsp/pagecontainers/controparteveicolo.jsp"
/> </action>
My approach: I extract from session the bean I use to initialize the form.
I do this in the action which is called before passing the request to the
JSP which implements canalizzazioneCLDForm:
//this bean defines the listaDanneggiati property
PartiteDanneggiatiView partite = new PartiteDanneggiatiView();
// extract from session the bean which returns the listaDanneggiati
ArrayList SessionBeanContainer beanContainer=
getSessionContainer(request);if (beanContainer != null)
{
//this is obvious
partite.setListaDanneggiati((ArrayList)beanContainer.getListaDanneggiati());}
// puts form into the request
setFormIntoTheRequest("canalizzazioneCLDForm", partite, request);
//....................
Now the request is passed to the JSP:
.............
<html:form method="post" action="/canalizzazione_cld.do">
<nested:iterate property="listaDanneggiati" type="DanneggiatoDto">
<nested:text styleClass="inputText" property="cognome"/><br/>
<nested:text styleClass="inputText" property="nome"/><br/>
<nested:iterate property="oggColpiti" type="OggColpitoDto">
<nested:text styleClass="inputText"
property="descrizioneGenerica"/><br/>
<nested:text styleClass="inputText"
property="tipoGenerico"/><br/> </nested:iterate>
</nested:iterate>
</html:form>
................
when I submit the form I get the following

but if I change the scope of the action above to "session" and I call
setFormIntoTheSession() instead of setFormIntoTheRequest() all works nice.
This is obvius, but my problem is: I don't like to set the action scope to
"session". Is there a way to set it to "request" and let all working
right?
thanks in advance
