Describe the bug On screen load isn't triggering on previewed apps. This does seem to be working for published apps, this makes it a bit of a pain to check your on screen load actions. As you need to publish every time you make a change to see it being affected.

To Reproduce Steps to reproduce the behavior:

1. Go to your design screen
2. Add an update state action with the value of test to your on screen load
3. Reference this in a paragraph component
4. Click the preview button
5. See error - no test is outputted.

Expected behavior On screen loads should trigger in preview mode as well as published apps.

App Export If possible - please attach an export of your budibase application for debugging/reproduction purposes.

Hi, As a workaround, we use the Interval plugin with an initial timer at 1 sec (which is not perfect, but we cannot have less). The timer actions:

• Continue If {{ State.Init }} is not 1
• Notify user (just to check it's not running endlessly)
• Set {{ State.Init }} to 1
• Set other required State values for initializing the page

The Interval plugin is of course not displayed (Display component in frontend set to false in builder). Conditions : Hide component if {{ State.Init }} is not empty Hiding the Interval component just stops it.

That makes the job even though it's not perfect. We could improve it by checking the document.readyState==="complete" in step 1 of the Interval's actions.
