Seam scope problem

[zemanel]

Hi,

I'm using:
jboss-seam-2.0.1.GA
ICEfaces-1.7.0-bin
jboss-4.2.2.GA

I think this is seam scope related problem:
I created a dataTable on backbean and it works fine, then i created an expandable table on the xhtml page and it works fine, but if i use both at the same time on the same page, they are both rendered but when i try to expand/collapse the expandable table nothing happens unless an exception saying:

09:24:39,878 WARN  [lifecycle] executePhase(RESTORE_VIEW 1,com.icesoft.faces.context.BridgeFacesCont
ext@127f2bb) threw exception
javax.el.PropertyNotFoundException: /home.xhtml @25,62 binding="#{tableManager.dataTableContas}": Target Unreachable, identifier 'tableManager' resolved to null
     at com.sun.facelets.el.TagValueExpression.setValue(TagValueExpression.java:95)
     at com.sun.faces.lifecycle.RestoreViewPhase.doPerComponentActions(RestoreViewPhase.java:244)
     at com.sun.faces.lifecycle.RestoreViewPhase.doPerComponentActions(RestoreViewPhase.java:249)
(...)
     

This is my table created on the tableManager backbean:
               
<ice:panelGroup>
     <ice:dataTable binding="#{tableManager.dataTableContas}">
     </ice:dataTable>
</ice:panelGroup>
     

And this is my table created directly on the .xhtml page:

<ice:panelGroup>
                    <ice:dataTable id="dataTableTest"
                         value="#{salesRecordsManager.salesGroupRecordBeans}"
                         var="salesRecord" columnClasses="expandableTableColumn">

                         <f:facet name="header">
                              <ice:columnGroup>
                                   <ice:headerRow>
                                        <ice:column rowspan="3"></ice:column>
                                        <ice:column rowspan="3">teste </ice:column>
                                   </ice:headerRow>
                              </ice:columnGroup>
                         </f:facet>

                         <!-- contract/expand column -->
                         <ice:column>
                              <ice:panelGroup styleClass="#{salesRecord.indentStyleClass}">
                                   <!-- Render the expand/contract if there is an image -->
                                   <ice:commandLink id="expandCmdLnk"
                                        actionListener="#{salesRecord.toggleSubGroupAction}">
                                        <ice:graphicImage id="expandContractImage"
                                             value="#{salesRecord.expandContractImage}"
                                             style="border: 0px solid;" />
                                   </ice:commandLink>
                              </ice:panelGroup>
                         </ice:column>
                         <!-- Description column -->
                         <ice:column>
                              <ice:panelGroup style="width: 60px;">
                                   <ice:outputText id="description"
                                        value="#{salesRecord.description}" />

                              </ice:panelGroup>
                         </ice:column>

                    </ice:dataTable>
               </ice:panelGroup>
     

I saw some other posts related to binding so i tried to change the scope from CONVERSATION to SESSION/EVENT and it gives me an different exception:

10:40:52,792 WARN  [lifecycle] executePhase(RESTORE_VIEW 1,com.icesoft.faces.context.BridgeFacesCont
ext@eb49a5) threw exception
javax.el.PropertyNotFoundException: /home.xhtml @21,85 binding="#{tableManager.dataTableHeader}": Property 'dataTableHeader' not writable on type com.icesoft.faces.component.ext.HtmlDataTable
     at com.sun.facelets.el.TagValueExpression.setValue(TagValueExpression.java:95)
     at com.sun.faces.lifecycle.RestoreViewPhase.doPerComponentActions(RestoreViewPhase.java:244)
     

Any idea how to solve this? thanks for any help/tips

Best Regards
