Resizing the window triggers onload and onunload events

Bug reports
1

Hi!

When we resize the browser window, we noticed that event handlers like “On View Load” and “On View Unload” are called.
This seems unintended since resizing the view shouldn’t get it unloaded or loaded. It led to some problems, for example when the user was inputting unsaved changes to the view and they resized the window they can lose their work in progress, which is confusing and frustrating.

Thanks!

Hi @hoi ,

Thanks for reaching out! I tried to reproduce the issue but wasn’t able to. Could you provide more details on how you have set things up and under what conditions this happens?

For example:

  • Which browser and version are you using?
  • Does it happen consistently or only in specific cases?
  • Are there any specific components or logic tied to “On View Load” or “On View Unload” that might be affecting this?

Any additional details would help me investigate further. Looking forward to your response!

Hi Simona, thanks for the reply.

  • We tested on Google Chrome Version 132.0.6834.83 (Official Build) (arm64) and Safari Version 18.0.1 (20619.1.26.31.7) and got the same results.
  • It happens consistently in our app. Any time we connect any actions to the event handlers of a view, they will get called when we resize the view.
  • The actions set for On View Load and On View Unload are only used there and are very simple, just Update object in App Variables. So it was really weird when we saw them getting called when we resized the window.

I also failed to reproduce the problem in a new and clean app, so it must be something in our current app that caused this. Can you tell me more about when the On View Load and On View Unload actions are called? Is there any custom logic there? That’d make it a bit easier for us to find something that potentially affects this.

Hi @hoi,

Could you try duplicating the app and see if the issue persists in the copied version?
