Probleme with update field

[turpin_vincent]

hi,

I'm using JBPM in seam 2.1.1

I' trying to update value in a datatable from an input text, but i've got a probleme. In fact i've got an entity called "sinstre" witch is scoped like that:

@In(scope = ScopeType.BUSINESS_PROCESS, required = false)
 @Out(scope = ScopeType.BUSINESS_PROCESS, required = false)
 private Sinistre sinistre;

In my XHTML page, ive got a Form:

 <h:form id="InfosVoiture">

 <h:outputText value="Il n'y a pas de sinistre a renseigner pour le moment" rendered="#{empty taskInstancePriorityList}"/>

 <rich:panel>
 <f:facet name="header">Lsite des sinistre comportant une partie materiel </f:facet>
 <h:dataTable value="#{taskInstancePriorityList}"
 var="task" rendered="#{not empty taskInstancePriorityList}"
 bgcolor="#F1F1F1" border="10">

 <h:column>
 <f:facet name="header">
 <h:outputText value="Creation"/>
 </f:facet>
 <h:outputText value="#{task.taskMgmtInstance.processInstance.start}">
 <s:convertDateTime type="date"/>
 </h:outputText>
 </h:column>

 <h:column>
 <f:facet name="header">
 <h:outputText value="Employe"/>
 </f:facet>
 <h:outputText value="#{task.actorId}"/> <br />
 </h:column> $
 <h:column>
 <f:facet name="header">
 <h:outputText value="task"/>
 </f:facet>
 <h:outputText value="#{task.name}"/> <br />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Id du sinistre" />
 </f:facet>
 <h:outputText value="#{task.variables['sinistre'].idSinistre}" /> <br />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Nom du client"/>
 </f:facet>
 <h:outputText value="#{task.variables['sinistre'].nomClient}" /> <br />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Prenom du client"/>
 </f:facet>
 <h:outputText value="#{task.variables['sinistre'].prenomClient}"/> <br />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Corporel"/>
 </f:facet>
 <h:outputText value="#{task.variables['sinistre'].sinistreCorporel}"/> <br />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Materiel"/>
 </f:facet>
 <h:outputText value="#{task.variables['sinistre'].sinistreMateriel}"/> <br />
 </h:column>

 <h:column>
 <f:facet name="header">
 <h:outputText value="Voiture task"/>
 </f:facet>
 <h:outputText value="#{task.variables['sinistre'].typeVoiture}"/> <br />
 </h:column>

 <h:column>
 <f:facet name="header">
 <h:outputText value="Voiture"/>
 </f:facet>
 <h:outputText value="#{Saisie_1.sinistre.typeVoiture}"/> <br />
 </h:column>

 <h:column>
 <f:facet name="header">
 <h:outputText value="type de Voiture"/>
 </f:facet>
 <h:inputText id="typeVoiture" value="#{Saisie_1.sinistre.typeVoiture}"/>
 </h:column>

 <h:column>
 <f:facet name="header">
 <h:outputText value="type de Voiture task"/>
 </f:facet>
 <h:inputText id="typeVoitureTask" value="#{task.variables['sinistre'].typeVoiture}"/>
 </h:column>

 <h:column>
 <s:button action="#{Saisie_1.test}" taskInstance="#{task}" value="autoriser modif" />
 </h:column>

 <h:column>
 <s:button action="updated" taskInstance="#{task}" value="update" />
 </h:column>

 <h:column>
 <s:button value="ajouter" taskInstance="#{task}" action="#{Saisie_1.Ajout_Mat(Saisie_1.sinistre.typeVoiture)}">
 </s:button>
 </h:column>
 <h:column>
 <s:button value="afficher" taskInstance="#{task}" action="#{Saisie_1.AfficherVariables}">
 </s:button>
 </h:column>

 </h:dataTable>
 <div>
 <h:commandButton value="Mise a jour des champs" action="update" rendered="#{not empty taskInstanceList}"/>
 </div>

I tried many way to update a value in my entity from an input text in the datatable. the only way i find (with done what i want) is starting a task with a button, then use a

<h:commandButton value="Mise a jour des champs" action="update" rendered="#{not empty taskInstanceList}"/>

and then use an other button to end the task (and merge the value in an other database but that's not the actual probleme).But it's a very ugly way.

So can someone tell me how can i do that in a better way and if i sould use a s:button or something like that.

BTW, i know that in my XHTML file there is many useless field but i use it in order test some ways and see many thing.

thx by advance

In addition i would like to know how i can start a task automatically when it's created, i try with:

<task-node name="Saisie_materiel">
 <task name="RemplirMat">
 <event type="task-create">
 <action>Saisir_1.test</action>
 </event>
 <assignment actor-id="#{actor.id}"/>
 </task>
 <transition to="join" name="toJoin2"></transition>
 </task-node>

but it dont seem to work
