Restrict user to add a time on specific days in time tracking sheet

 Hi

we get the date using getStartDate() method of ITimeSheetEntry and
using that date we get the specific day for e.g Monday,Tuesday by
dayFormate.format(getStartDate()) method.

this pluigin is working fine for localhost server but when we deployed it
on server its not working as expected.

below is my precondition tag

<precondition id="net.atos.ssc.time.tracking.input.extnid" name="Time Tracking Input Validation"  xmlns="http://net.atos.ssc.time.tracking.input/server/extnid">

<time-tracking-input-configuration>
<days-of-week-to-restrict id="Monday"/>
</time-tracking-input-configuration>
</precondition>

Please help me for the same.
