DuplicateClientIDException in jsfUnit

Question

Hi!

In my test I looking for some components, and checking if they're rendered:

UIComponent component = server.findComponent(permossion.getClientId());
        assertEquals(hasPermission, "roleCol");

and my page looks like this:

<p:treeTable value="#{manageGroupsBean.root}" var="entity" id="table">
                <p:column id="roleCol" >
                        <h:outputText value="#{entity.group.name}" 
                          rendered="#{manageGroupsBean.isGroup(entity)}" />
                                </p:column>
                          </p:treeTable>

and more...

When I run the test it give an arror:

'roleCol' matches more than one JSF component ID. Use a more specific ID suffix. Suffix matches: table:0:roleCol,  table:1:roleCol, 
org.jboss.jsfunit.jsfsession.DuplicateClientIDException:

When I degug it (org.jboss.jsfunit.jsfsession.ClientIDs class)I see it cteated a list of like 180 compnents, and it has both table:0:roleCol and table:1:roleCol. (it checks acroding to the suffux). I know that the id unique, just maybe it duplicates it for enerty row in the table or something like that.

Could anyone help me?
