Add Subtaxa exception for custom taxonomy (v5.4) - Sitefinity - Bugs & Issues

I just wanted to report a bug, which is a NullReferenceException on SaveChanges when adding a new Taxon to Subtaxa in a custom hierarchical taxonomy.

The workaround is to set the Taxonomy property on the new Taxon (this is not in described in the documentation examples). I experienced this problem with version 5.4.

Sample code:

teacherTaxon = taxonomyManager.CreateTaxon<HierarchicalTaxon>();

teacherTaxon.Taxonomy = teacherClassesTaxonomy; // REQUIRED

teacherTaxon.Name = teacher.Username;

teacherTaxon.Title = teacher.TeacherName;

schoolTaxon.Subtaxa.Add(teacherTaxon);

taxonomyManager.SaveChanges();

Regards,

Gary
