Issue upgrading from 3.7.1 to 4.0.3

[nazario1]

The following worked in 3.7.1 but is giving an exception in 4.0.3

uncaught exception: jqGrid - No such method: navGrid, also same error for navButtonAdd

          $("#myTreeGrid").jqGrid('navGrid','#myTreeGridPager',{view:false, edit:false, add:false, del:false, refresh:false, cloneToTop:true},{}, {}, {}, {multipleSearch : true}, {closeOnEscape:true})
          .jqGrid('navButtonAdd',"#myTreeGridPager",{caption:"", buttonicon:"ui-icon-refresh", onClickButton:envHandleRefresh, position: "last", title:"Refresh", cursor: "pointer"})

What replaced the navGrid and navButtonAdd methods? Is there an alternative syntax that will work instead?
Thanks,

Oscar, I've started working this issue and it appears that the jqgrid support in the latest struts2 release does not include the treegrid libraries.

Is anyone out there monitoring this issue or have some suggestions as to a work-around other than not upgrading?
