| Summary | 0002676: JvInterpreter: Call of derived methods does not work | ||||
| Description | I have defined a new class TRemoteQuery, descendent of TClientDataSet, which is desendent of TDataSet. I have also defined my method TRemoteQuery.Open. But instead of calling my new method TRemoteQuery.Open, JvInterpreter calls TDataSet.Open method. The problem is in GetMethod function of TJvInterpreterAdapter.GetValue method. After calling FGetList.Find(Identifier, i) function, it checks (((Args.ObjTyp = varObject) and (Args.Obj is JvInterpreterMethod.FClassType))... Open method of TDataSet is situated in FGetList list prior to TRemoteQuery.Open method, so it will be checked first. Now, since TRemoteQuery is descendent of TDataSet, then "Args.Obj is JvInterpreterMethod.FClassType" will return true, which will cause the *WRONG* method to be called (instead of TRemoteQuery.Open); I have attached the modifications of GetMethod function and FGetList.Find() method that will avoid this problem (check my comments); | ||||
