Filter row in grid

[preeti_kanyal]

Hi,
I am using 6.1-p20190721 smartGWT.

I am using a databound grid having dynamic criteria for this. Now i am trying to enable filter row on this grid using :
grid.setShowFilterEditor(true)

But it throws exception on fetch operation for filter row. Does it do a fetch operation for filter row as well?
If i disable filter editor there is no exception.

When the user enters criteria into the filter editor, a fetch to the server may be initiated depending on whether all data that match the current criteria are cached, and whether the new criteria are more restrictive. For a more detailed explanation, see the docs for ListGrid.fetchData() and the ResultSet class overview.

There are also automatic fetches for ListGridFields where the respective ds.xml field has a foreignKey.
You should see failing fetches in the RPC Tab of the developer console. The metadata in the fetch should give you a hint about the field that issued the failing fetch.
