When using Turbolinks and I visit a page that has a Stimulus controller the controller’s initialize function is called twice. Here’s a gift showing it happening [screen] Here is the example Rails app I used to create that gif. https://github.com/scottharvey/stimulus_asset_pipeline I’m not sure i…

I had something similar happen but it was because I was sending an HTML fragment with the data-controller attribute from the server. This was causing it to connect again when that fragment was added to the DOM.

I believe everything is working as expected here. You’re seeing Turbolinks’ preview cache in action: [D]uring standard navigation (via Application Visits), Turbolinks will immediately restore the page from cache and display it as a preview while simultaneously loading a fresh copy from the network…

I’m using The latest Stimulus with Rails 7 … Now I’m observing this behavior only whenever I do hard refresh to the page … then I try to active an action, it goes twice !!

I am facing same in rails 7. did you find an work around for it. I am stuck at it.

when calling: <%= javascript_importmap_tags %> just make sure to disable shims. For some reason, the shims is importing the controllers twice. It should look something like this: <%= javascript_importmap_tags shim: false %>

Thanks @sam, that totally makes sense. Everything seems to be working as you described.
