Hi all,

I've encountered a little pb here:


=========================================================
saisie.jsp
======================================================================
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>

<f:loadBundle basename="popup" var="msgPopup" />
<f:loadBundle basename="jourSaisie" var="msgsJourSaisie" />
<f:loadBundle basename="command" var="msgsCommand" />


<f:subview id="subviewSaisieTableId">
<t:saveState value="#{semaineSaisieBean.semaineSaisieId}" />
<h:inputHidden id="inputSemaineId"
value="#{semaineSaisieBean.semaineSaisie.semaineSaisieId}" />

<t:newspaperTable var="rowJour"
value="#{semaineSaisieBean.semaineSaisie.jourSaisieList}" id="El_pais"
newspaperColumns="7">
<h:column>
<h:panelGrid columns="1" styleClass="table_m" headerClass="th_m"
rowClasses="td_m">
<f:facet name="header">
<h:panelGroup>
<hutputText value="#{rowJour.nomDuJour}" />
<hutputText value="#{rowJour.dateSaisie}">
<f:convertDateTime dateStyle="long" type="date" timeZone="GMT+2:00" />
</hutputText>
</h:panelGroup>
</f:facet>

<h:panelGrid columns="1">
<f:facet name="header">
<hutputText value="#{msgsJourSaisie.morning}" />
</f:facet>
<h:selectOneMenu value="#{rowJour.tempsTravailAM.projetId}"

</f:facet>
<h:selectOneMenu value="#{rowJour.tempsTravailPM.projetId}"

</f:subview>

basically, the aim of this is to save a list of jourSaisie (day entries for a sort of scheduler) with each jourSaisie having a tempsTravailAM/PM (working Time).
So we have the following objects:
SemaineSaisie --> jourSaisie --> tempsTravail --> projetId

We have mapped these in a hibernate(SQL) dB.

We can create a list of these objects but we can't save the tempsTravailId in the table of jourSaisie (many to one relationship), although we can save the semaineSaisieId in jourSaisie (one to many relationship).

We think the problem comes form the fact that we have two types of tempsTravail (distinguished by the type element in the TempsTravail.class)


in case you want to look at our methods :


this is first called when we get to our page (saisie.jsp)
=====================================================================
semaineManager.class
=====================================================================
public void saveAllObjectsFromSemaine(SemaineSaisie semaineSaisie) {



ArrayList jourList = (ArrayList) semaineSaisie.getJourSaisieList();
ListIterator it = jourList.listIterator();

SemaineSaisie semaine = (SemaineSaisie) saveReturnObject(semaineSaisie);

while (it.hasNext ()) {

JourSaisie jour = (JourSaisie) jourList.get(it.nextIndex());

TempsTravail travailAm = jour.getTempsTravailAM();
TempsTravail travailPm = jour.getTempsTravailPM();
travailAm = (TempsTravail) saveReturnObject(travailAm);
travailPm = (TempsTravail) saveReturnObject(travailPm);

jour.setTempsTravailAmId(travailAm.getTempsTravailId());
jour.setTempsTravailPmId(travailPm.getTempsTravailId());
jour.setSemaineSaisieId(semaine.getSemaineSaisieId());
jour.setJourSaisieListIdx(it.nextIndex());

save(jour);

it.next();
}
}
=====================================================================




these are thes methods we call with SemaineSaisieBean.save
!! But the jsf page never actually gets into it , it just reloads...
=====================================================================
SemaineSaisieBean.class
=====================================================================
public void saveSemaine(ActionEvent e) {
System.out.println("START SemaineBean.saveSemaine()");

/*
* semaineSaisie.setEmployeId(1); semaineSaisie.setStatut("ouvert");
* semaineSaisie.setTotalSemaine(1);
*/

semaineManager.save(semaineSaisie);

saveJourList(semaineSaisie.getJourSaisieList(), semaineSaisie
.getSemaineSaisieId());

System.out.println("END ActionBean.saveAppli()");
}


private void saveJourList(List jourList, int id) {

for (int i = 0; i < jourList.size(); i++) {

JourSaisie jour = new JourSaisie();

jour = (JourSaisie) jourList.get(i);

jour.setJourSaisieId(id);

TempsTravail travailAm = jour.getTempsTravailAM();
TempsTravail travailPm = jour.getTempsTravailPM();

if (jour.getTempsTravailAmId() == 0 && jour.getTempsTravailPmId() == 0) {

} else {
travailAm = (TempsTravail) semaineManager
.saveReturnObject(travailAm);
travailPm = (TempsTravail) semaineManager
.saveReturnObject(travailPm);
jour.setTempsTravailAmId(travailAm.getTempsTravailId());
jour.setTempsTravailPmId(travailPm.getTempsTravailId());
}


semaineManager.save(jour);
}
}
=====================================================================




thanks for helping. (and reading ;->)
