Seam scope problem

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
