On which version did you encounter this issue?
I was not able to reproduce your result with "" empty string on the latest version - but I see a similar effect with null instead.

Testing on 0.12.1 shows the following result:

linkcollection / linkcollectionselect

  1. with {multiple: true} - 3 states
  • null - if there was never a link set for this entry+field
  • [] - empty array if at least 1 link was once set set but meanwhile reset/removed again
  • [{LINK_OBJ},...] - array of link objects if links are set
  1. with {multiple: false} - 2 states
  • null - if there is currently no link set yet / link was reset/removed
  • {LINK_OBJ} - link object if a link is set

Bug or feature

So one could argue it’s a bug to show

  • an empty array [] when multi-links were reset
  • but null if there were never any links set

One could also argue it’s a feature to know if there is no-value-yet vs no-value-anymore.

:rofl:
I think we should go with a Feature Request to have the same output null or [] :wink:
Thinks like that are frustrating when you have to figure it in FE
