Converting circular structure to JSON

merobal commented 4 years ago

Environment

Please provide as many details as you can:

Formio.js version: 4.5.1
Frontend framework: 4.8.1
Browser: Chrome
Browser version: latest

Steps to Reproduce

https://angular-formio-custom-demo.netlify.com/

Add a Table component.
Add any component. The components will disappear.
Add any component again. This error message will appear in console: Infinite loop detected undefined 500

Expected behavior

No error message, no circular reference.

Observed behavior

Circular reference, error message in console.

I cannot reproduce our issue with the demo app (only the infinite loop), but internally we get this error message:

Uncaught TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'Object'
    --- property 'component' closes the circle
    at JSON.stringify (<anonymous>)
    at fastCloneDeep (utils.js:1350)
    at TableComponent.get (Component.js:2883)
    at get (<anonymous>)
    at TableComponent.get (NestedComponent.js:730)
    at get (<anonymous>)
    at TableComponent.get (Table.js:85)
    at Webform.js:1783

We will add this to our developer list to investigate.

@travist do you have any update on this?

jeriah-formio commented 4 years ago

@merobal Could you try using the latest version of formio.js to see if this resolves the issue?

merobal commented 4 years ago

Still, the same issue using "angular-formio": "4.6.7" I updated the version at the demo site, you can try the repro by following the "Steps to Reproduce" mentioned above...

As suggested by @merobal, we had to revert to 4.3.3 to get around this. Please have a look.

Getting same issue with angular-formio renderer for existing forms. Any form with data grid and components added into it is giving error: Infinite loop detected undefined 500.

This is causing some other problems with the form:

nextPage() not firing intermittently.
Validations getting triggered automatically after this error.
Browser getting crashed
submission data is getting refreshed automatically

@travist Do you know the last stable version of angular-formio that I can use?

travist commented 4 years ago

We are aware of this as a possible high priority bug. We have our planning sessions Monday and I should know more about when we will see resolution to this after that point.

dmenne commented 4 years ago

With 4.3.3 I have not seen the infinite recursion, but it nevertheless is suspicious that the component is created twice on every call redraw. Might be the source of the issue.

Still having the same issue with "angular-formio": "4.6.10"

travist commented 4 years ago

Thanks for the bump... I will ensure this is added to a developer on our teams list this week, or maybe early next week.

@merobal, I've tried to use angular-formio "4.6.10"/"4.6.7" and formiojs "4.5.1", but, unfortunately, was not able to reproduce the issue with disappearing components . Maybe you could give us more details on your environment?

merobal commented 4 years ago

@travist FYI I realized the issue, in this case, was I saved the form to a local model and I passed back to the formio component.

So the fix for my demo is: https://github.com/merobal/angular-formio-custom-demo/commit/1a4a96280637b986997388e05aa2662d71e957fd
