Hi,

i have seam .xhtml page with a orderinglist like this:

<rich:orderingList id="list" value="#{clItems}" var="cli" >
 <rich:column>
 <f:facet name="header">
 <h:outputText value="value (%)" />
 </f:facet>
 <h:outputText value="#{cli.value}" />
 </rich:column>
 <rich:column>
 <f:facet name="header">
 <h:outputText value="time (ms)" />
 </f:facet>
 <h:outputText value="#{cli.time}" />
 </rich:column>
</rich:orderingList>

There are two problems with this constellation.
Using a Vector of a pojo with properties time and value, the list is rendered correctly the first time, but when i post the surrounding form, the item is suddenly of type String, an there is an Exception that .value is not a property of String. Using String only items is not sufficient for the application. there have to be 2 colums with individual properties.

So i use a entitybean as item class, and create a factory in the backingbean that creates the List<> of items and annotyte the list with @DataModel.
Very much the same as shown in the examples.
I tried the backing bean and the entity with a datatable component in the .xhtml page, and it works as expected.
But when using the above mentioned orderinglist, i have the following exception:
