[jira] Created: (TOMAHAWK-1435) t:dataTable sorting Problem

t:dataTable sorting Problem
---------------------------

                 Key: TOMAHAWK-1435
                 URL: https://issues.apache.org/jira/browse/TOMAHAWK-1435
             Project: MyFaces Tomahawk
          Issue Type: Bug
          Components: Data List
    Affects Versions: 1.1.8
            Reporter: Klaus Schuster


Hello, 
I am trying to use t:dataTable from Tomahawk to build a sortable table. The sort criteria (column which is used for sorting, asc vs. desc) should persist (in the session) so that when the use comes back to table after visiting other pages the same sort criteria should be automatically applied he used the last time. 
After perusing the API I thought this should be possible with these attributes. 
      
preserveDataModel="false"     
preserveSort="true"   
sortColumn="#{verein.sortColumn}"   
sortAscending="#{verein.ascending}">     


However I cannot make it work. The sorting criteria are stored in my backing bean, but when I navigate back to the table they are not applied. 

I am using tomahawk-1.1.8.jar on Websphere 6.1
