[jboss-user] [JBoss Seam] - fail to persiste taskinstance variables from xhtml page

I initially post this to the jbpm forum but I think it is more related to the jboss seam forum. In the thread of the jbpm forum I have written to consider that entries closed since I planned to create this entry in the seam forum.

I have modified the todo example to add an xhtml form for the todo task.
The todoform.xhtml follows.

When I submit the form with "Done command" button, the description of the taskinstance is persisted in the database but not the variable1. The variable1 is created in the jbpm_variableinstance table but there is no value set (null).

So what I have done is to use the @In in the todolist component and then on the todolist.done method I save the variable using 

TaskInstance.instance().setVariable("variable1", comments);

However, I don't think it is the way to do thing with jsf-seam-jbpm integration. That is why even if I have found a workaround I am asking the question. 

Do you have an answer for that?



Here is my xhtml file that is that save de taskintance.description but not the taskInstance.variables['variable1'].

Todo List

   <h:form id="list">
       id: <h:outputText value="#{taskInstance.id}"></h:outputText>
       name: <h:outputText value="#{taskInstance.name}"></h:outputText>
       description:<h:inputText value="#{taskInstance.description}" style="width: 400"/>
       summary:<h:inputText value="#{taskInstance.variables['variable1']}" style="width: 400"/>
	<h:commandButton value="Update Items" action="update"/>
        <h:commandButton value="Done command" action="#{todoList.done}"/>
