Bad validation message

[jma]

Description
A wrong validation message is displayed with arrays.

Minimal Reproduction

Here you can find a stackblitz reproduction example. If you click on submit we got a required error message instead of a minLength. Let us know if we need to open an issue.

Thanks in advance.

it is required to pass an empty string for that case, if I'm not wrong. Please try the following solution instead:

"items": {
  "type": "string",
  "minLength": 0,
+ "default": ""
}

Unfortunately, this does not work. Here is a modified example:

In fact a field with an parent field of type array should never be required at least for a JSONScheam. The required property is only available on the object type thus only for the children of an object field. I tried to add a patch in the prePopulate of my extension, but changing the required property of a field change also the required property of the children...

Unfortunately this is the case. You have introduce a new bug in the version 6.3.4. Using the following stackblitz example the field "new" is not marked as required anymore:

The issue here is when/in which case an array item is considered required. here is how it is handled:

• Object is underlined, name field is not required
• Object set, name field is required

If I understood well, you want to make a input field required only when a field is touch, but we have several problems here. Running the following modified example:

1. after loading the editor is ok
2. after clicking on "submit" the validation message is wrong: the array is not required but need at least one item, thus the error message "This field is required" is wrong.
3. now if a new item is added, we can see that the form is valid which is not true, if we try to validate the model against the JOSONSchema, the "new" property is missing as it is required.
4. If I enter a "space" in the "new" field and suppress it (the field is touched), the message "This field is required" appears but I cannot go back to the situation before I touched the field.

Thanks in advance for your reply.
