I am getting java exception error after running a multiobjective optimization function (gamultiobj) by means of the optimization toolbox, just right after the function/problem terminates.

I can see all the plots that are generated, refreshing with every generation, I see the Pareto front plotted everything looks fine. Except that I can't access the decision variables and function values in the Pareto front (after the optimization terminated).

The window looks like this for me:

After termination I get the following message in the command window:

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 0

at com.mathworks.mwswing.DefaultSortableTable$TableSorter.compareRowsByColumn t com.mathworks.mwswing.DefaultSortableTable$TableSorter.compare(DefaultSortableTable.java:267) at com.mathworks.mwswing.DefaultSortableTable$TableSorter.shuttlesort(DefaultSortableTable.java:353) at com.mathworks.mwswing.DefaultSortableTable$TableSorter.shuttlesort(DefaultSortableTable.java:324) at com.mathworks.mwswing.DefaultSortableTable$TableSorter.shuttlesort(DefaultSortableTable.java:324) at com.... etc. etc. (like 50 of these lines)

Is there any solution for this? Can I access the data some other way? Thank you for your help in advance!
