TfrReport/GetVariableValue - access violation

Hi dear Mr. FastReport,

Inside "TfrReport.DoBuildReport" and "TfrReport.PrepareReport" I see you assign these events: 
  frParser.OnGetValue := GetVariableValue;
  frParser.OnFunction := OnGetParsFunction;

in "TfrParser.CalcOPZ" I see: 
  if Assigned(FOnGetValue) then
    ...

And you never clear these events.

frParser object is global object. After I destroy my TfrReport object (or I destroy form/unit owner of the report object) these events are undefined.

In this case, it is possible to get access violation error (I do! specific case, but possible). And I think this have to be corrected.

Thanks,
Plamen.
