            <set name="flowRequestContext.externalContext.sessionMap.testCompleted" value="yes"></set>
        </on-entry>
.....
    <on-exit>
    <set name="flowRequestContext.externalContext.sessionMap.testCompleted" value="no"></set>
    </on-exit>
</view-state>

Please edit your post and format it correctly. Don't use block-quote notation for code, indent it 4 spaces. — Jim Garrison, May 26 '12 at 17:45

I found the problem, within double quote I have to wrap value with single quote to represent it as a value otherwise it expect a expression here.

 <set name="flowRequestContext.externalContext.sessionMap.testCompleted" value="yes"></set>

it should be

<set name="flowRequestContext.externalContext.sessionMap.testCompleted" value="'yes'"></set>
