MultiValue reset

RagnarGrootKoerkamp

It would be nice to have a public function to reset multiValue fields to their initial state, or more generally a function to reset any field to its initial state.

Context:

We have a from with checkbox fields A, B, ..., and dependent fields A1, A2, B1, `B2,...
The child fields are only shown when the parent checkbox is on.
We would like to do the following when multiple rows are edited: (the problem is in the third item)

• If all rows have A checked, show A1, A2 as normal fields, with the usual multiValue behavior. When A is unchecked, the child fields are hidden. (Their value is cleared at the server, so this is fine.)
• If none of the rows have A checked, the child fields will be shown when A is clicked. All child fields start empty, so the normal behavior works well.
• If A is a multiValue, the child fields are hidden initially. When A is checked, the children are shown. Their default multiValue behavior is used. (so far so good) Now, when A is reverted by clicking undo changes, I would like to revert the child fields to their initial state as well, but I don't see how to do this in a nice way. Some of the child fields could be in a multiValue state, so calling the private multiReturn.on('click') function would work, but some might be non-multiValue fields, and I don't know of a way to change those back to their initial state.

That's interesting - thank you. I hadn't included this ability because I figured that if you were using the API you wouldn't be using the UI for the multi-row editing at the same time. Obviously that isn't the case with your use case.

I can't promise anything as there is a significant feature back log at the moment, but I will look into implementing this. Thanks for the suggestion.

Just a quick thought - perhaps another option would be to read the existing values from the table and use the API to set those values when the event occurs.

Resetting values by reading them from the table should work well indeed. Thanks!

This will still require a custom event when Undo Changes is clicked, but that should be easy to implement myself.

Just a quick update here in case anyone else finds this - I've added field().multiRestore() to the Editor API which will be available in 1.7.
