NullPointerException in "Test with file" function if no "data header regexp" is specified

[Johan Vallon-Christersson]

When using Annotation importer. Input file is small and contains two columns (attached). Choose to 'Test with file'. I knew that I had 2 data columns so I specified min/max. Click 'Parse the file' and get an error (below).

If I do not specify min/max data columns and click 'Parse the file' I do not receive the error.

If I specify Data header regexp '\QName Extract_Major_Type\E' and specify min/max data columns I do not receive the error.

File for annotation import

[Nicklas Nordborg]

It happens because the functionality in the "Column mappings tab" depends on the presence of a data header. Since no regexp is specified we can of course not find any header. Instead we should fall back to mapping columns by index.
