Solution

Replace on-render tag with on-entry , it will work. 

<view-state id="displayAllTasks" view="/WEB-INF/flows/jsp/displayAllTasks.jsp" model="workflowSet">
<on-entry>
<set name="requestScope.state" value="requestParameters.state"/>       
<evaluate expression="workflowController.getAllTasksByState(requestParameters.state)"   result="viewScope.workflowSet"></evaluate>
</on-entry>
