Lab report file is not created when BatchTask is run on a multi-dimensional parameter space

[maxxkia]

I tested my code for a one-dimensional parameter space (one value for each parameter) and the program runs fine and my .csv lab report file is created. But when I ran the program again with multi-dimensional parameters, the final lab report file was not created; although, results.prop files were created in each "ExperimentTask-..." folder.

I also noticed that the log file says it stored the results, but actually there's no file. Here's a line from program output:

168697507 [main] DEBUG de.tudarmstadt.ukp.dkpro.lab.storage.filesystem.FileSystemStorageService  - Storing to: ./TEMP/DKPRO_HOME/de.tudarmstadt.ukp.dkpro.lab/repository/BatchTask-bb9cde67-23e9-11e5-800b-57317237455e/RESULTS.csv

If that message "Storing to ..." appears, then a file is created. However, it is deleted again if during the production of the file an error occurs. So if your report throws an exception, then there is no file. But you should then see some error message from the report in the logs.

But there is no error following this entry in the log. You can check the last lines of log here:
