The catNames function in the Data Manager task crashed if no columns were selected.

This error no longer occurs, and an empty column is returned as a result.

The Apply Model task did not display results correctly in the Results tab when there are multiple models.

This issue has now been resolved.

Database queries on SPARK did not work if comments or multiple statements were present, due to a limitation in the given ODBC driver.

This limitation has now been overcome in the software:  multiple statements are now separated and useless comments are erased before passing the required query to the ODBC driver.
