OOZIE decision with nested EL expression

[Sabbidi, Prashanth]

Hi,

Is there any way to work with nested EL expressions in oozie.

I need to get the path dynamically, inside decision node. My directiory path is 
 ${parsedDataLocation}/${wf:id()}
Where parsedDataLocation  is from job properties.


                <case to="preCleanup">
                ${fs:isDir(wf:conf(parsedDataLocation)/wf:id())}
            </case>
