Exception error after Reaction commit to building block

[UlrichSi]

1. Open ManualModel_Sim.mbp3
2. Open the Reactions BB, then add a +global+ parameter to reaction R1.
3. Update simulation S1 from Reactions BB, then open it. - These steps were all preparation to add a feature that will allow a "Commit" after change.
4. Change the value of the newly added global parameter in R1. Reaction will be flagged red in S1 configuration.
5. Commit Reaction to building block.
6. Open Reaction, then click on any reaction symbol in the chart (or switch to the list and click there).

The following exception is thrown, build 36 was used:
