in my XPages views I'm using the keys property (data > data > keys) to get a subset of documents. Every thing works fine so far. But if I setup an column as sortable and click on the header to sort this column I get an Unexpected runtime error with an exception: "Too many keys".

The column in the Notes View is setup as sortable for both directions. If I don't filter the view by using the keys property the column get sorted w/o an exception.

Any ideas how to work around?

Thx for helping me.
