                 Key: RF-3842
                 URL: http://jira.jboss.com/jira/browse/RF-3842
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.2
         Environment: IE6, IE7, FF 3.0, Opera 9.27, Safari 3.1
            Reporter: Mikhail Vitenkov
         Assigned To: Pavel Yaschenko


Step 1. Get selection from scrollableDataTable using findComponent following way:
<h:panelGrid columns="2">
		<rich:column>
			<a4j:commandLink value="getSelection" reRender="findID"></a4j:commandLink>
		</rich:column>
		<rich:column>
			<h:outputText id="findID" value="#{rich:findComponent('sdt').selection}" />
		</rich:column>
	</h:panelGrid>
'sdt' - id of the component.
Step 2. Select any row of the scrollableDataTable.
Step 3. Click 'getSelection' link.

Actual behavior:
javax.faces.FacesException: Exception while decoding component : {Component-Path : [Class: org.ajax4jsf.component.AjaxViewRoot,ViewId: /pages/Rich/Rich.jsp][Class: javax.faces.component.html.HtmlForm,Id: formID][Class: javax.faces.component.html.HtmlPanelGrid,Id: richGridID][Class: javax.faces.component.html.HtmlPanelGroup,Id: j_id_jsp_357983163_10][Class: javax.faces.component.UINamingContainer,Id: scrollableDataTableSubviewID][Class: org.richfaces.component.html.HtmlScrollableDataTable,Id: dataList]}
