REST API - How do I get the Bean Validation message?

Support
#1

I’m trying to implement bean validation with guidance from the docs, but it just doesn’t seem to be working as expected.

The validation is functioning properly - it errors out when it should. app.log is showing the proper validation message. But the REST API does not return this message. The response shows, roughly, the following:


{
  message: "",
  response: {...}
}

The message is empty, whether I return a custom validation message or not.

I’m guessing that I missed a step, or something. Any ideas on what that could be?

The service method I am testing is as follows in the interface:


    @Validated
    @NotNull
    ServiceResult<Pdetail> reactivateLineitem(
            @NotNull
            Pdetail lineitem,
            Date startDate,
            @Future(message = "Date must be in the future")
            Date endDate,
            BigDecimal amount
    );

The code I’m using to call the service (the parameters include a date that is well within the past, so as to trigger the @Future constraint):


this.app.invokeService("muaipm_AccountService", "reactivateLineitem", this.params_reactivate, {
  handleAs: "json"
}).then(function(response) {
  ...
}.bind(this)).catch(function(response) {
  console.log(response)
  console.log(response.message)
}.bind(this))

I am strictly using the Polymer front end, and haven’t touched the GUI.

What am I missing?

Hi
try to add @Validated annotation also to validated parameters, like @Validated @NotNull and so on, then report back here…

I tried your recommendation, but unfortunately it didn’t change anything.

Sheepishly I must admit that I just didn’t use the Javascript API properly.

What worked was to do as follows:


this.app.invokeService("muaipm_AccountService", "reactivateLineitem", this.params_reactivate, {
  handleAs: "json"
}).then(function(response) {
  ...
}.bind(this)).catch(function(response) {
  response.response.json().then(function(json) {
    json.forEach(function(error) {
      console.log(error.message)
    }
  })
}.bind(this))

Specifically, the (simplified) .response.json().then((json) => json[some_index].message).

Thanks for your willingness to help!
