[EP-tech] Problem with creating the browse view

CAUTION: This e-mail originated outside the University of Southampton.
Dear David and team,

I'm encountering an issue while trying to create a browse view for uncontrolled keywords in my EPrints repository (version latest 3.4.7).

I am trying to create a browse view that displays individual keywords as clickable links, with tag cloud and without tag cloud and A-Z grouping variations. However, I keep getting the following error:

I used two type of variation but failed to create the browse view:-

eprint_fields.pl:

{
name => 'keywords',
type => 'longtext',
input_rows => 2,
},

views.pl:

{
    id => "keywords_browse",
   
    menus => [
        {
            fields => [ "keywords" ],  # Removed ;tags
            hideempty => 1,
            new_column_at => [15, 20],
        },
    ],

    variations => [
        "keywords,cloud,cloudmax=250,cloudmin=80,jump=plain", # Removed ;tags
        "keywords,first_letter", # Removed ;tags
        "DEFAULT"
    ],

    order => "-date/title",
    citation => "screen",
    hideempty => 1,
},

{
    id => "keywords_test",
    menus => [
        {
            fields => [ "keywords;tags" ],
            hideempty => 1,
        },
    ],
    order => "-date/title",
    citation => "screen",
},

getting this error:


EPrints System Error

BAD METAFIELD get_property property name: "render_tags"
Field: keywords, type: longtext


---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  1. I also try to change the field type to keywords but the error persists even after changing the field type to keywords
  2. The error mentions render_tags property not found, suggesting the keywords field type might not be fully recognized
  3. Without the ;tags option, the view works but displays keywords as a single comma-separated string rather than individual link
  4. I have seen one video where you split the title into a single string using automatic fields but can it be achieved without this. what if we can used different separator apart form comma or semi colon then ?
  5. I even didn't find any documentation regarding this.

Thanks and Best Regards,
