I just solved my problem. I was trying to get my taskInstance to be signaled
with code when I thought about another solution :
I don't put a dataform inside my form but the form inside my dataform. This way
the default transition button can still work and I just have to put some
javascript on it like that :
<jbpm:dataform>
| <f:facet name="header">
| Envoyer un fichier local
| </f:facet>
| <jbpm:datacell>
| <f:facet name="header">
| Selectionnez le fichier a envoyer :
| </f:facet>
| <form name="uploadFile" enctype="multipart/form-data"
method="POST" action="uploadSuivi">
| <input class="file" type="file" name="suiviXLS"/>
| <input class="text" type="hidden" name="nomProjet"
value="#{var['nomProjet']}"/>
| </form>
| </jbpm:datacell>
|
| <jbpm:datacell>
| <f:facet name="header">
| <h:outputText value="Actions"/>
| </f:facet>
| <tf:transitionButton transition="OK" value="Envoyer"
onclick="document.forms['uploadFile'].submit();"/>
| </jbpm:datacell>
| </jbpm:dataform>
It works well, my task is validated, the next task is created, my servlet is
called and my file saved... I'm happy but I'm feeling very stupid to think
about that so late. I knew this should be easy :)
Btw I think a little more documentation must be written on EL (some examples
would be great) and since jBPM JSF tags are still here in the new admin console
and usable from jBPM and JSF users, I think they deserve a little Javadoc like
the official JSF one :
http://java.sun.com/javaee/javaserverfaces/1.2_MR1/docs/tlddocs/index.html.
That's absolutly not a urgent task... but it would help...
