> I'm using the viewParam in my JSF page and it works well at first request, but when I send another request using ajax the value of viewParam is lost. This issue only happens when I use javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL=true. When I use  javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL=false it works well.
