In a nutshell the issue I’m facing is that every time I register alpine’s @ or x-on event handler, two are registered and called when the action is performed.
The issue is solved if I comment liveSocket.connect(), which leads me to believe the problem is in the interoperation of liveSocket and Alpine.
I’ve circled the internet without success. Has anyone had this issue and solved it?

Does it work if you get rid of
Alpine.start()? Importing might automatically start it.fceruti
Nothing happens, the event handlers are not present. Alpine is not started in the import.

You got an
x-dataon that div, or its parent?fceruti
Yes there is, I updated my original post to show more context.
cmo
what’s the rendered html look like for the bit inside
{#for date <- @dates}?fceruti
This is the page full html (ps: I made a few updates to the original post)
view-source:127.0.0.1:4000/app/calendar
What you are asking is inside the element with id
week-calendar-days-containercmo
Probably doesn’t matter but you have a random
"in the divs with the IDs<div id="day_col_2021-11-09"?I’ve had to use alpines
templatetag (wrapped in aRawtag - I use surface) for somewhere where I generated a list of things which had myriad alpine bindings. Unfortunately, I’ve stepped away from the computer for the day so I can’t show you an example.fceruti
By any chance are you back yet? I’m stilll having this issue
cmo
Here is a cut down version. Note that I’m using Surface, hence the
<#Raw>tags (I assume there is a parallel in plain old liveview) and different syntax. The hook reads attributes from the hiddenspans and sends them to Apline. Alpine creates the html for the options. I had a bit of trouble getting this to work and when it worked I stopped touching it and moved on. I hope to revist if/when I get some timeHook:
