Change validation messages after rejected PATCH-Request

Engines
1

Hi,
Is there an Action or any other save way to change the validation state of a certain field in the FormEngine?
The <PROJECT_NAME>-Usecase: There is validation logic that can only be computed on the Server and it will be triggered as soon as the Client sends a PATCH-Request on a resource. The Validation should not be separated from the PATCH-Request and thus cannot be called via an own Request in the course of a validateFull or validatePartly Action. The Server doesn’t implement anything of A12, but the resource will be edited on the Client in a A12 FormEngine, so we need a way to change the validation state of the Form manually.
Any Ideas how to solve this requirement?

Kind Regards,
Alex from <PROJECT_NAME>

Hi @alexander-pure-wind,

After receiving the validation information from server, you can dispatch the setMessageState

api.dispatch(FormEngineActions.command({
	engineEvent: Commands.setMessageState({
		messages: {} // messages receive from server
	}),
	activityId: action.payload.activityId
}));

to replace all error messages in the form. There is another action which is Commands.setMessageStateEntry to replace the message that you want to change.
Hope it helps :slight_smile:

Sorry for responding late. Yes, it helped! Thank you!

I want to add, that I spent a while searching for an error, because i misspelled one of the needed strings inside message and didn’t get a hint what went wrong.
For everyone else, who is wondering, how it should be formatted, a message object looks like this:

api.dispatch(
  FormEngineActions.command({
    engineEvent: Commands.setMessageStateEntry({
      messageStateEntry: {
        validationMessages: [
          {
            element: [
              { elementName: "yourContainer", index: 1 },
              { elementName: "yourField", index: 1 }
            ],
            errorCode: "anyErrorCode",
            errorKey: "anyUniqueErrorKey",
            errorText: "Any Error Text that get's displayed.",
            referencedFields: [
              [
                { elementName: "yourContainer", index: 1 },
                { elementName: "yourField", index: 1 }
              ]
            ],
            severity: "ERROR"
          }
        ],
        path: "/yourContainer[1]/yourField[1]"
      }
    }),
    activityId: action.payload.activityId
  })
);

…It might look different if your Field is nested deeper.

Kind regards,
Alex
