Editor loses focus if data is changed and displayed

Hi!
Thanks for reporting this..

Can u please use this link and check if this behaviour happens?

https://stackblitz.com/edit/angular-json-editor?file=src%2Fapp%2Fapp.component.ts

Sure, I forked your example and added the assignment: https://stackblitz.com/edit/angular-json-editor-uodqc5

And just to make sure that we are talking about the same thing:

I am fully aware that it is impossible to automatically do much about the changing data itself: If the bound data changes there may be any number of conflicts that can't be resolved automatically. I do not expect any meaningful cursor position or expansion state if the bound data changes randomly! This is basically the same scenario a text editor is in when it detects that the edited file has changed on disk. And it resolves that by asking the user what to do: "Keep the state from the editor" or "Reload from disk"? Imho this kind of logic is far outside the scope of this neat little wrapper.

But maybe it would be possible to somehow preserve some state like the previous position of the cursor and the selected mode? At least for minor edits this should do the trick.

Gotcha!

My question is.. why you need to change the data? If you need to save this on database, just call the ajax, or if you need that in another component, you can call a event or service to pass it on

Because the problem here is to update the same data you used to build the jsoneditor

[MarcusRiemer]

I use the editor as a (weak) excuse to postpone some "real" UI writing (screenshot 2 and 3). The edited data models are quite complex, so building their UI simply takes a while. Having some kind of two way databinding allows loads of experimentation: You can change the model from the (only partially finished) UI and from the editor.

As I said: I wouldn't expect the actually edited data to survive or to get merged. But I would love to see "trivial" parts the editor state preserved when changing the data. Currently even if I only "write back" the data selectively (shown in the first screenshot) things like the selected mode are lost.

Screenshot 1: Selective update, asking the user "Data has changed, which version do you prefer?"

Screenshot 2: Hardly any UI at all, only a JSON-editor

Screenshot 3: A little UI, but still a JSON-editor

Thanks!!

I think i got a solution for you, check version 1.6.2.. if is not working as expected please reopen
