Hi

I wonder if anyone can help with this puzzle. It has been exercising me all afternoon and I am getting lost in the detail.

I am trying to create a field called thesis_type_display. The purpose is to give a properly formed citation for any reference to a thesis. Currently, I see something like this example:
Boice, John Richard (1970) A history and evaluation of the school construction systems development project, 1961-1967. Doctoral thesis, Stanford University.

The name of the thesis is not the way I would expect to see. I expect, instead of ‘Doctoral thesis’ something in the form of ‘Unpublished PhD thesis’. Thus, I set up a field called thesis_type_display in /cfg/cfg.d/eprint_fields_pub.pl:

{              name => 'thesis_type_display',

               type => 'text',       

},

I also set up a phrase in /cfg/cfg.d/zz_webcfg.xml:

<epp:phrase id="eprint_fieldname_thesis_type_display">Thesis type display</epp:phrase> (which appears in my Admin/Phrase editor)

And I have been struggling in the workflows and renders to get this to replace the current variable thesis_type in the presentation of a citation. I have no ended up with a rather difficult error when I click through to view an item:
XML::LibXML::Node::appendChild() -- nNode is not a blessed SV reference at /opt/eprints3/perl_lib/EPrints/Language.pm line 288.

So, I am in the process of reverting any other files that I fiddled with and wondered whether there is a straightforward way to deal with this.

Thanks in advance
