Trigger "changeId" only if content change

[Noodlex]

Trigger "changeId" if the content is modified.

Null or undefined are identical in the process.

Could you clarify why you think null and undefined should be considered equivalent? This is different from the semantics of the regular change and change:[attribute] events.

[Noodlex]

It's a proposal.

I have a case where I have a collection in a model.
I receive the complete model with the collection and the new attributes.
These are different and in some cases, I end up with a “prevId” = undefined and a this.id = null.

The behavior seems the same to me in the case of avoiding triggering the “changeId” event, but I'm well aware that undefined is different from null.

To be honest, to me this seems like a situation one would rather avoid in the first place. I am not convinced yet, but maybe you can show me some example code?

I don't yet have time to investigate the source of the problem. Currently, this fix on my version allows me to avoid “changeId” trigger problems.

I'll try when I'm less in a rush to find the exact source and maybe add the right fix.

I'll close this request and come back later if needed.

Thanks for your time.
