implement converter for your objects and override hashCode and equals properly.

problems with LS and OL components could be easilly checked with rich:messages. Samples at rivcfaces-demo.

Hi,

<rich:orderingList value="#{contractBacking.postValidationItems}" var="lib" listHeight="300" listWidth="350" columnClasses="name,value" >
<rich:column >
<h:selectManyCheckbox id="postvalidationItems" value="#{contractBacking.selectedPValidationItems}" layout="pageDirection">
<f:selectItems value="#{lib}"/>
</h:selectManyCheckbox>
</rich:column>
</rich:orderingList>


After form submission i am getting the following error message as
*Expected a child component type of UISelectItem/UISelectItems for component type javax.faces.SelectMany(postvalidationItems). Found java.lang.String.*

Please help me to provide solution for this

<f:selectItems value="#{lib}"/>

Hi,

<rich:orderingList value="#{contractBacking.postValidationItems}" var="lib" listHeight="300" listWidth="350" columnClasses="name,value" >

Actually "#{contractBacking.postValidationItems}" contains SelectItems and also i am assigning this binded property to variable lib.While first time page is loaded i am able to see all the checkbox items that are assigned to
contractBacking.postValidationItems.But After selecting some checkbox items and submitting the page i am getting the already mentioned error message. Please help me to provide solution for this
