["Xiong Zhang" <xiong.zhang@xxxxxxxxxxx>]

-Summary:
ScriptEvaluationError when preview blank data item

- Bugzilla Bug (s) Resolved:
158252

- Description:
when user creates or edit a data item with no expression, we just create
a data item with no resultset property set.
The data item definition in the report design should look something like
this <data id="77"/>. UI does not have to create a corresponding binding
column.
