Created attachment 45662 [details] Authority Merge Page Blank (Koha 3.22 on Ubuntu 14.04 LTS - package installation) Objective: Attempted to merge name authority A into name authority B. Error: After choosing the reference authority, the merge page is blank with neither the source table nor destination table populated with data (see https://www.dropbox.com/s/f0ez3cmtrlr8xvd/AuthorityMergePageError.docx?dl=0). After clicking the Merge button anyway, the following error appears: Software error: Can't call method "data" on an undefined value at /usr/share/koha/lib/C4/AuthoritiesMarc.pm line 1491. After checking to see if the merge was successful, it was not, and the reference authority disappears from the authorities index.
Hi Craig, I think this might be a duplicate of bug 15358.
