SmartGWT 2.2

If it can help Isomorphic in debugging: I drag and drop a record from a source list grid to a target list grid (named ParticipantsListGrid in the log). I use a RecordDropHandler in the target list grid to manage the drop event. BEFORE the execution flow enters the RecordDropHandler (so in SmartGWT code, not in my own code) I can see the following in the console

com.smartgwt.client.core.JsObject$SGWT_WARN: 09:32:50.841:MUP3:WARN:ResultSet:isc_ResultSet_2 (created by: isc_ParticipantsListGrid_0):get: invalid index -2

I have the impression that SmartGWT code is adding a record to the target list grid before entering the RecordDropHandler (just a guess) and I do not know how to prevent that.

Kind regards
