MEV can't open data files that has a missing value in the last column

The BioAssaySetExporter can export data in MEV format. The export contains annotation values for all experimental factors. But the exported file can't always be opened by MEV. The "Slide data loading" is stopping at 0% with no error message (when running the Java web start edition shipped with BASE).

It seems like this happens if the bioassay in the last column is missing a value for at least one of the experimental factors. If the last columns has a value for all annotation MEV can read the file. Missing values in other columns than the last are handled without any problem.

There seems to be a similar issue if there is a missing intensity value in the last column.

I have tested to output N/A instead of the empty string for missing annotation values and NaN instead of missing intensity values. This makes sure that the last column is never empty and it seems like MEV can open the file. I am not 100% sure that this doesn't create other side effects.
