Issue with oj-sample-export-data

Content

Hi Shay,

There are couple of issue I am facing with oj-sample-export-data

1 - If any one of the columns contains null value  then in the exported excel it will take the value of next column which contains values

ex -  {
            "emp_id": 1,
            "emp_name": "ABC",
            "comm": null,
            "Salary": 1000
        }

In Exported excel comm will have value as 1000

2 - If I define Click Event on oj-sample-export-data, any activity defined in that action chain gets executed twice. ex if i call a REST service in that action chain to populate ADP, it gets called twice and exported excel does not contain any data even though ADP is populated.
