I have a taxonomy called Species, and another taxonomy called Protected Areas.
Inside of the Protected Areas I have a multifield widget (Taxonomy reference pointing to Species), where user can select different Species present on the Area.
Users are able to manipulate also the Species taxonomy, when adding a new Species they are able to choose in which Protected Area is this specie present. Then, when users do it, I would like to automatically update the user selected Protected Area taxonomy (for this Species), adding on the multifield widget the recently added Species value.
Even shorter: how to communicate new/changed values between taxonomies.
Some chances to avoid writing my own module? thanks
