When editing features on a layer the current opened feature's layer is depending on (with layer dependencies), virtual fields considering these values are not updated "on the fly".

Does not work on single forms.

Not sure if we can call it a bug, but I think it's an expected behavior from virtual fields.

  • Having a reference with parent "wald" and child "baum"
  • Having a layer dependency on layer "wald" for layer "baum"
  • Having a relation editor widget on the "wald" form
  • Having a virtual field on the "wald" form with the expression relation_aggregate( 'bauminwald','count', "baum_id") and alias "counting children"

virtual_fields_depending_childs

This works on attribute table form:
attr_table_update
(but leads to issue: #43902)

This is probably related to #43900
