[v3] window._wails.dispatchWailsEvent is undefined on "Reload" #4872
Description
Description
Reloading a page on the frontend should cleanly reload like in browser. However there seems a race condition where in, likely, the WindowLoadFinished event is fired before the _wails is mounted on the window global. Future events are delivered fine, suggesting its likely a timing issue.
To Reproduce
- Create a new v3 project with:
wails3 init -n app - Run the app:
cd app && wails3 dev - Right click and click "Reload" on the frontend window.
- See the error on the console:
TypeError: window._wails.dispatchWailsEvent is not a function. (In 'window._wails.dispatchWailsEvent({"name":"linux:WindowLoadFinished","data":null})', 'window._wails.dispatchWailsEvent' is undefined)
Expected behaviour
The page should be cleanly loaded without the above error. The initial load doesn't show the error.
