Working but not clean

Notice: Undefined property: TaxonomyTerm::$vid

Should be TaxonomyTerm::$vocabulary, or $term->vocabulary.

Also you will need to replace $vocabulary->vid with $vocabulary->machine_name in line 142. In Backdrop, Vocabularies don't use the numerical vid anymore.

One more suggestion: the original module used the table variable to store configurations. In Backdrop, config files are preferred (they allow, for example, easy exports/imports). See https://docs.backdropcms.org/change-records/variable_get-variable_set-and-variable_del-deprecated-by-cmi

(variable_get and variable_set are deprecated)

Thanks @indigoxela @argiepiano - I've changed the $vocabulary->vid coding. Where did you find the variable @argiepiano ?

Where did you find the variable @argiepiano ?

@djzwerg not sure if I saw that in an earlier version of the module - now I see that it's using a config file, and the variable is removed in the update_1000 hook.

Intermediate status: the selected views are displayed in the frontend but the selection field in the backend is still empty after saving.
