Expression error

[mvlach]

Hi,

I have some function to check dynamically if display or not display the link. The function is implemented throught workflow and when I put in the xhtml page this expression:

#{workflowProcessor.getWorkflow(t).hasAction(t, Workflow.ACTION_S_ACCEPT)}

on the page appears true or false.

When I put this expression to the <s:link ... rendered="     #{workflowProcessor.getWorkflow(t).hasAction(t, Workflow.ACTION_S_ACCEPT)}
">

...

I get the exception:

javax.faces.FacesException: javax.el.ELException: /listticket_tablecontrol.xhtml @12,49 value="#{ticketList.resultCount}": Error reading 'resultCount' on type cz.bpsolutions.servicedesk.actions.lists.TicketList_$$_javassist_3

When I remove the rendered attribute from s:link all works fine. Know somebody what kind of error is thrown ?

Thanks Mila

[gjeudy]

how does workflowProcessor name gets resolved? is it produced by a

@Factory

or an

@Autocreate

annotation ?

Transaction is not active error usually hides the root exception. JSF and/or Seam is known to swallow exceptions sometimes.

You can read this thread for my own experience with this: Transaction Is Not Active With Create Annotation

In any case your best bet is to run in debug mode to find what is causing your transaction to be in ABORT ONLY state.

I've been successfully tracking this down by putting a breakpoint in

org.jboss.ejb3.tx.Ejb3TxPolicy

that would require you to download jboss source code. If not you probably can set a breakpoint in some seam interceptor but I don't know how much success you will get there. I think some other people recommended

org.jboss.seam.transaction.RollbackInterceptor

as a good place to put your breakpoint..

Hi, thanks for your reply.

At first, I am not using EJB3. I am using the Seam Pojo components. The workflowProcessor is the Seam component (POJO).

The workflowProcessor is created (loaded) in listticket.xhtml - there is no @Factory, no @Autocreate.

I hope I tell you what you ask me.

Thanks Mila

[mvlach]

Hi, you are right.

The problem is there:

a.xhtml code fragment

<rich:dataTable value="..." var="t">
#{workflowProcessor.getWorkflow(t).hasAction(t, Workflow.ACTION_S_REJECT)}
</rich:dataTable>

The a.xhtml works good.

the b.xhtml fragment

<rich:dataTable value="..." var="t">
     <s:link view="/viewticket.xhtml" rendered="#{workflowProcessor.getWorkflow(t).hasAction(t, Workflow.ACTION_S_ACCEPT)}">
          <h:graphicImage value="/img/reject.png"
               title="#{messages['ticket.detail']}" />
          <f:param name="ticketId" value="#{t.id}" />
     </s:link>
</rich:dataTable>

The b.xhtml works not good - because the getWorkflow get NULL value of  the first argument (Ticket t)

I don't know why ?

Thanks Mila

[gjeudy]

Could this be some incompatibility between richfaces and seam tags ? if you put h:outputLink does your t value get propagated there ?

[mvlach]

Hi,

using the h:outputLink doesn't solve my problem. The parameter is still null.

Is curious, that

#{workflowProcessor.getWorkflow(t).hasAction(t, Workflow.ACTION_S_REJECT)}

work good and this works not good:

<h:outputText value="#{workflowProcessor.getWorkflow(t).hasAction(t, Workflow.ACTION_S_REJECT)}"></h:outputText>
