f:viewParam does not work for the second ajax request and so forth the submitted value is null in JBoss EAP 7.2

Solution In Progress - Updated -


The viewParam in a JSF page works well at first request, but when another request is sent using ajax, the value of viewParam is lost. This issue only happens when it use javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL=true. When it use javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL=false it works well.
