Uncaught TypeError

[Ali-Zmn]

Sometimes when my initial values in FormRenderer does not include all fields, I face this error:
Uncaught TypeError: Cannot read properties of undefined (reading 'initial') at eval (condition.js?3893:72:1)
I would assume if the initial value is not in FormRenderer initialValues it would pick the Schema initialValue and if no initial value is provided in the schema, it should keep it empty, right?

I couldn't reproduce it in codesandbox and in my code, if I rerender my component (reload) a couple of times, it works fine!
Do you have any idea?

Seems that it happens here:

react-forms/packages/react-form-renderer/src/condition/condition.js

Line 57 in bb71375

if (typeof meta.initial === 'undefined' || meta.modified) {

I guess there could be some problem when a condition is triggered during a render or so. We will take a look tomorrow.

Maybe we could add some flag to the condition to set behavior on initialValue, what do you think @Hyperkid123 ?

[Hyperkid123]

@rvsia I am definitely against changing the default behavior. That has the potential to mess up many existing forms.

If necessary we can add a flag as you suggested with the standard priority. Schema prop > renderer props.

[rvsia]

On other hand, consumers can just remove the initial value from their schemas/initial values manually with no need to add some flag.

[Hyperkid123]

Yeah, that is why said if necessary.

Make sense! If it is the default behaviour, I'm with you.
Thanks
