[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-834) FileUpload (Progress bar cannot with this be used as it does not seem to pass on the Conversation)
[ http://jira.jboss.com/jira/browse/JBSEAM-834?page=comments#action_12354161 ]
Ted Goddard commented on JBSEAM-834:
------------------------------------
Initial testing with Ajax Push fixes applied (invoking both execute() and render() during
Ajax Push) does not resolve the problem with FileUpload.
The complexity discovered with FileUpload is that the file upload servlet needs to relay
events to the application so that the application can push page updates illustrating file
upload progress (potentially in an application-dependent manner, but typically this is
simply a progress bar). This event relay is performed via a callback on an application
bean, but this occurs outside of the JSF lifecycle (it is simply invoked from the
FileUpload Servlet) and appears to fail to prepare the Seam interceptors correctly.

Key: JBSEAM-834
URL: http://jira.jboss.com/jira/browse/JBSEAM-834
Project: JBoss Seam
Issue Type: Bug
Components: ICE Faces Integration
Affects Versions: 1.1.6.GA
Reporter: Tony Herstell
Assigned To: Gregory Dick
Priority: Minor
Don't use the progressListener
<!-- progressListener="#{uploadController.progress}" -->
as it throws a "no long running conversation" exception in seam in the backing
bean.
<ice:panelGrid columns="1">
<ice:inputFile style="border:none; width:400px; height:70px;"
actionListener="#{uploadController.action}"/> <!--
progressListener="#{uploadController.progress}" -->
<ice:outputProgress id="progress"
value="#{uploadController.percent}"/>
</ice:panelGrid>
