Hi,
I'm trying to do row grouping based on the values in a column. If the column is completely full, grouping works fine. If I try to group and one of the cells is a blank value, I get the following error:
Uncaught TypeError: Cannot read property 'push' of undefined pqgrid.min.js:289
This is a column I would like to group on, but it may not necessarily have an entry in each cell. You can see the same behavior in
http://www.paramquery.com/pro/demos/group_rows if you change the groupModel dataIndx to dataIndx: ["ShippingDate", "ContactName"],
Since the shipping date might be missing a value in some entries, it completely breaks if you try to group on it.
