Provide more useful error than "Invalid type, expected array"

[upq]

I get this error while the output is exactly how I expect it, the problem is that the form is invalid.

Form

form =    {
                                        "key": "data.answers",
                                        "type": "array",
                                        "items": [
                                            {
                                                "key": "data.answers[]",

                                                "items": [
                                                    {
                                                        "key": "data.answers[].text",
                                                        "type": "text",
                                                        "title": "Question",
                                                    },
                                                ]
                                            }
                                        ]
                                    },

Schema

        scope.schema = {
                        "type": "object",
                        "title": "Types",
                        "properties": {
                            "data": {
                                "type": "object",
                                "title": "data",
                                "properties": {
                                    "answers": {
                                        "type": "array",
                                        "title":"Answers",
                                        "default": [],
                                        "items": {
                                            "type": "object",
                                            "title": "Answer",
                                            "properties": {
                                                "text": {
                                                    "title": "Answer",
                                                    "type": "text",
                                                    "required": true,
                                                },
                                            }
                                        }
                                    }
                                }
                            }
                        }
                    };

expected output

data = {answers: [{text: "answer1"}, {text: "answer2"}], correct: 1, question: "questioning?"}

Now the expected output is right but the form is invalid saying that it expected an array, anything Im missing here?

[toomuchdesign]

Same problem here. The validation error (Invalid type, expected array) appears when adding a second item into an array field.

It seems to be a problem related to angular-schema-form-bootstrap. I have no troubles when using the old decorators included in ASF folder.

This is my current setup:

• angular 1.4.8
• angular-schema-form 0.8.12
• angular-schema-form-bootstrap 0.2.0

I'm going to investigate on this in the next days and set up a plunkr if needed.
Any hint would be great!

@upq back to your example: are you sure about setting "type" properties to "text"?

I suppose the correct type for your text items in Schema declaration should be "string" ;-)

Follow the schema in the official examples:
http://schemaform.io/examples/bootstrap-example.html#/ce1076e82a119133ebd6

"text": {
    "title": "Answer",
    "type": "string",
    ...
}

Meanwhile I found an acceptable solution.

I had the validation issue when trying to get an array of textarea-strings:

[ "Lorem ispsum", "Lorem ispsum", "Lorem ispsum",]

I was able to overtake the validation issue by setting the field up as an array of objects as described in the demo:

[ { "text": "Lorem ispsum" }, { "text": "Lorem ispsum" }, { "text": "Lorem ispsum" }]

@toomuchdesign changing the type to string actually worked! its always something dead silly and simple that is missing..

[jugglingcats]

I'm not sure this should have been closed. While @upq had a typo in his schema, @toomuchdesign did not and had to use a workaround that changed the schema.

We have the following schema fragment:

                    "features" : {
                        "type" : "array",
                        "title" : "Features",
                        "items" : {
                            "type" : "string",
                            "required" :true
                        }
                    }

This works fine with the old decorator but breaks with the new one giving the on-screen error described. We can't easily use the workaround as the documents already created follow the schema above.

I have recently had the same issue but it was due to the data returned from the server changing null to empty string on a field, but rather than show a useful error, I got the above. Suffice to say it took some time to determine that the returned string was failing the array item as it was defined as being an integer value. I think we need to look at improving the feedback on this one.

[toomuchdesign]

@Anthropic, I confirm your issue: empty strings values returned by the server breaking the validation. I ended up with iterating the returned data object and removing empty values before sending data to the server.
