RichFaces ShuttleList sample doesn't work in a Seam framewor

[todd.nash]

In an effort to validate the errors with the ShuttleList in my own pages, I decided to see if the sample works in a Seam framework.

I have found that many of the Richfaces components don't work well when used in a Seam framework. Are you guys testing anything using Seam?

I only modified the sample code enough to avoid any Seam errors. Specifically, I had to remove the UIEventsBouncer because org.ajax4jsf.component.UIDataAdaptor doesn't exist in the Richfaces jars and you can't include the ajax4jsf jars when using Seam.

The following error occurs in both 3.1.3 and 3.1.4.

When I click the submit button on the page containing a ListShuttle I get the following error:

javax.el.PropertyNotFoundException: /documents/listShuttle.xhtml @52,55 value="#{item.name}": Property 'name' not found on type java.lang.String

Here is the xhtml page I modified from the samples:

I am also trying to use listShuttle with Seam framework and get the same error when trying to submit the page with ListShuttle. I am using version 3.1.4

SEVERE: Error Rendering View[/createHierarchy.xhtml]
javax.faces.FacesException: javax.el.PropertyNotFoundException: /createHierarchy.xhtml @46,63 value="#{entity.entityDefI
d}": Property 'entityDefId' not found on type java.lang.String

Anyone any suggestions ?

I get the same. With richfaces in portlet.

Hi guys,

I've managed to work with seam and listShuttle

here is some code :

<rich:listShuttle id="available_groups" sourceValue="#{available_groups}"
 targetValue="#{selectedGroups}" var="gr"
 listHeight="300" listWidth="300"
 sourceCaptionLabel="Available Groups"
 targetCaptionLabel="Currently Selected Groups"
 converter="groupConverter" >

 <rich:column >

 <h:outputText value="#{gr.name}" />

 </rich:column>

 </rich:listShuttle>

@Begin(join=true)
 @Factory("available_groups")
 public List<Group> getGroups(){

 List groups = groupService.getGroups();
 return groups;

 }

and

@Out(required=false)
 List<Group> selectedGroups = new ArrayList<Group>();

You must have a converter and equals() on your entity.

Maybe this helps.

Cheers.

Could you please post your converter code ? Thanks
