Aggregation Invalid Javascript expression: ,.

KavithaD

Hi All,
I want to display Department wise Employees present for each day as comma separated.
For Eg::

Department Employees
dep1 emp1,emp2,emp3,emp4
dep2 emp5,emp6,emp7
dep3 emp1,emp4

So I used Aggregation builder in Expression i am checking for the date present and displaying Comma separated employees name and i am doing grouping on Department.

EXP :: if(dataSetRow["PRESENT_DATE"] != null){
dataSetRow["EMP_NAME"]
}

if i use Separator as , i am getting below exception other wise i am getting employees name with out Separation.


Please help me in resolving this issue.
