Strategy Tester Visualization crashes when ObjectCreate is called

[fifthfloor]

I had some trouble with the strategy tester visualization (which is a great tool) when the expert is creating objects on the chart.

Here is some sample code which forces the error when running in tester with visualization mode:

      ObjectSetInteger(0,Name,OBJPROP_COLOR,Color);
      ObjectSetInteger(0,Name,OBJPROP_STYLE,Style);
      ObjectSetInteger(0,Name,OBJPROP_BACK,false);
     }
  }

void OnTick()
  {
   static datetime Old_Time;
   datetime New_Time[3];
   bool IsNewBar=false;
   int copied=CopyTime(_Symbol,_Period,0,3,New_Time);
   if(Old_Time!=New_Time[0])
     {
      IsNewBar=true;
      Old_Time=New_Time[0];
     }
   if(IsNewBar)
     {
      MqlRates mrate[3];
      CopyRates(_Symbol,_Period,0,3,mrate);
      DrawLine("Object"+(string)LinieCount,New_Time[0],mrate[0].open,New_Time[1],mrate[1].open,clrPaleGreen,STYLE_DOT);
      LinieCount++;
     }
  }

Maybe this could be fixed in a future version.

I have checked and couldn't reproduced that. We need more details.

Yes, you are right. The code above runs without an error.

Just comment out the last line:

// LinieCount++;

So that ObjectCreate tries to create an object with an exsisting name.

The visualization will crash, while in demo trading, this works properly.

Thanks. We will check it.

Fixed. Please wait for the next build.
