Do Vault Field Dependencies trigger on the Language field upon upload?
Field Dependencies are not able to trigger upon upload for the Language field when using Multilingual Document Handling. Although Vault attempts to detect the source file's language upon upload, it only populates the language field. Since the Doc info page is in edit mode during document classification, this new value is not yet saved. At this point, the dependency still sees this field as being empty until the user presses the Save button.
Once the user completes classification, saves changes, and officially sets the value on the Language field, only then is any dependency able to act on the field.
