DEV-786 has brought in initial implementation of the multi-value fields based on Vaadin 8 and the re-worked concept of the forms.

However, the multi-field implementation is incomplete:

• there're no controls to add/remove child entry of the multifield
• there're no controls to change the order of the child entries
• the interface that manages the order of the child entries (MultiFieldOrderHandler) might need further improvements (see that whatever is supported by the multi-value transformers is also supported)
