DataAnalysisSolutionView throws an exception when switching the details off and on while displaying a chart

In the DataAnalysisSolutionView click on Classification Threshold, hide the details and show them again.

The following exception is thrown:

System.InvalidCastException: Unable to cast object of type 'System.RuntimeType' to type 'HeuristicLab.Optimization.IResult'.

Sorry for the vague description. Please have a look at the screenshot. Open the GP classification example and run it. In the Results View click on the Best validation solution. Click the Classification Threshold, then in the second step click on Show/Hide Details. Click the Show/Hide Details again and you should get the error message.
