Problem with Datagrid with dynamic data from data master
1) Datamaster contains shopping records of many users.
2) Variable "current-user" is used to set the current userid
3) When onPageLoad or onVariableChange( referring to current-user), Data grid displays shopping records from data master based on user id. Value of data grid is calculated using filter function.
4) Everything works well when there is at least 1 record per userid. I can change the value of current-user variable to see different records.
5) However, problem is when there is a current-user that does not exist in the userid column, the data grid will show nothing. And after this, no matter what value the current-user, the datagrid will never show up anymore.
