The only solution found is to prevent first table displaying using this code :
<%
//"result" is the id of the second table
ParamEncoder paramEncoder=new ParamEncoder("result");
String
parameter=paramEncoder.encodeParameterName(TableTagParameters.PARAMETER_EXPORTTYPE);
out.println("parameter" + parameter);
if (request.getParameter(parameter)==null) {
%>
<display:table id="...
<%
}
%>
Something really strange is that sorting and other features works correctly for
both tables.
Thanks by advance.
