Use $getId() as wire:key instead of rand

[neverything]

We ran into an issue when we were using the field for table filters with live() that the tree list kept closing after a single checkbox was clicked.

This PR changes wire:key="{{ rand() }}" to wire:key="{{ $getId() }}"

@neverything - this is similar to my PR #154 which uses a specific manageable treeKey and also adds the current url to the spa mode check.

hit the same issue you did (plus the spa check issue)

Wouldnt this also cause problems with reactive / live?

A while back i tried this and ran into problems like that.

[neverything]

@CodeWithDennis so far not, I'm using it with live() and have multiple filters per table. The only potential issue I could see is if the tree of options changes between requests.

@mgkimsal I like that approach. It would be cool if the default was still rand(), but allowing it to overwrite the wire:key if necessary using your approach from #154. Would you be open to a configurable approach @CodeWithDennis?

Would you be open to a configurable approach @CodeWithDennis?

Yes! Lets do that to make sure we don't break anything! (Default rand until we find something better) @neverything

[neverything]

@mgkimsal do you want to refresh your PR #154, or should I implement the configurable wire:key in mine?

[mgkimsal]

@neverything - lemme look

Apologies for delay. I made a small change in 'setup' to add a 'rand' call as a suffix. Does that do what you were thinking of?

Would like to use this and keep the 'url()->current()' call in the spa() call check as well.

This is in #154

Let me know when its ready to be checked, appreciate the help here guys. @mgkimsal @neverything
