Exception when trying to open the data preprocessing view for regression solutions

just-in-time (JIT) debugging instead of this dialog box.

Current trunk version

The exception only occurs as long as the solution is embedded in the algorithm results. When opened in another tab the data preprocessing opens without any problems.

r14332 Now, when opening Preprocessing from a ProblemData within a Solution, the outer Views (Problem or Alg.) are ignored. Thus, after preprocessing, only the ProblemData can be exported (no Alg. or Problem).

Reviewed and tested r14332.
