           Summary: Software error on authority edition when using merge
          Severity: critical
    Classification: Unclassified
                OS: All
          Reporter: fridolyn.somers at biblibre.com
          Hardware: All
            Status: NEW
           Version: master
         Component: Cataloging

When using the update of biblios on authorities edition (managed by 'dontmerge'
syspref), and when biblionumber is on a control field (< 10) :
When editing or creating an authority, you get a software error :
"Software error:
Control fields (generally, just tags below 010) do not have subfields, use
data() at /usr/share/perl5/MARC/Record.pm line 239
For help, ..."

This comes from the fact that, to find biblionumber in a record, one must check
if biblio.biblionumber is mapped on a control field to call
"$record->field($tagfield)->data" instead if
"$record->subfield($tagfield,$tagsubfield)".

It was also missing in batchImportMARCWithBiblionumbers.pl.
