[jboss-user] [JBoss jBPM] - gravel and j4j tags in datatable

[gnagy]

Hi,

I tried borrowing code from the jbpm console for listing tasks and making transitions. I iterate over #{taskInstanceList} in a datatable (tried both h:datatable and rich:datatable), but the gravel and j4j tags don't pick up the iteration variable.


<h:dataTable var="taskInstance" value="#{taskInstanceList}">
    <h:column>
        <f:facet name="header" >
            <h:outputText value="Deal info"/>
        </f:facet>    
        <h:outputText value="#{taskInstance.variables['dealTask']}"/>
    </h:column>
    <h:column>
        <f:facet name="header" >
            <h:outputText value="State"/>
        </f:facet>    
        <h:outputText value="#{taskInstance.task.parent.name}"/>
    </h:column>
    <h:column>
        <f:facet name="header" >
            <h:outputText value="Actions"/>
        </f:facet>    
        <ga:responseActions>
            <gd:sort source="#{taskInstance.availableTransitions}" target="#{transitions}" entryVar="e" argument="#{e.name}"/>
        </ga:responseActions>
        < ul>
        <gd:repeat value="#{transitions}" var="transition">
            < li>
                <h:commandLink>
                    <j4j:loadTask id="#{taskInstance.id}" target="#{j4jtask}"/>
                    <j4j:completeTask task="#{j4jtask}" transition="#{transition.name}"/>
                    #{transition.name}
                    <n:nav outcome="success" redirect="true" storeMessages="true"/>
                    <n:nav outcome="error" redirect="true" storeMessages="true"/>
                </h:commandLink>
            < /li>
        </gd:repeat>
        < /ul>
    </h:column>
</h:dataTable>


is rendered as:

Deal info	State		Actions
info1	 	Accepting Deal 	
info2 		Accepting Deal 	
info3 		Accepting Deal 	


i.e. the Actions column is empty.

Any ideas why gravel and j4j don't pick up #{transitions}? Note, it semi-works with ui:repeat, but then i have no chance to sort the set of transitions.

Also, is it ok to post further gravel questions in the jbpm forum?  Or do they belong elsewhere?

Thanks,
Greg
