student975 · April 22, 2021, 3:04pm

I’s want to rise BPMN Error from embedded from. Is it possible?

Niall · April 23, 2021, 6:10am

You can indeed.

<button cam-error-code="bpmn-error-543"
 cam-error-message="anErrorMessage" />

Take a look at this section of the docs to learn more about it.

@Niall Thanks for pointing, that is useful, but at the moment I’d want to rise error in javascript inclusion where camForm is in hands.

# Error and Escalation Events in Embedded Forms

This quickstart demonstrates how to use escalation and error events in embedded forms.

# Overview

## Where are Error and Escalation events defined?

Boundary Events can be added in the Camunda Modeler. Each can be referenced by its error- or escalation code.

![Modeler Screenshot][1]

## How are these events triggered from an embedded form?

Error events can be triggered by calling `camForm.error('error-code', 'error-message')` from a custom Script or using the `<button cam-error-code="error-code">` element.

Similarly, an escalation can be triggered using `camForm.escalate('escalation-code')` from a custom Script or using the `<button cam-escalation-code="escalation-code">` element.

## How to use it?

Error: camForm.error is not a function

Here is an example

github.com

StephenOTT/camunda-formio-plugin/blob/master/common/forms/formio.html#L465




    let errorMessage = (() => {
        if (_.has(submission, bpmnErrorMessageKey)){
            return submission[bpmnErrorMessageKey]
        } else {
            return bpmnErrorDefaultErrorMessage
        }
    })()


    if (_.has(submission, bpmnErrorCodeKey)){
        $scope.camForm.error(submission[bpmnEscalationCodeKey], errorMessage)
    } else {
        $scope.camForm.error(bpmnErrorDefaultErrorCode, errorMessage)
    }
})


form.on('submit', submission => {
    setupSubmissionVariables(submission)


    $scope.complete()
})

Both $scope.camForm.error as well as just camForm.error are undefined. 7.10 is in use. It is springboot app, probably some deps are missing. Aren’t they?

try using a new version of camunda.

student975 · April 23, 2021, 1:48pm

Unfortunately I don’t rule the service. At any casy it seems

            camForm.fireEvent('error', {
                errorCode: 'myCode',
                errorMessage: message
            });

must do the same thing. But for some reason still can not catch the errorCode with attached event.

Later: No, it doesn’t work.
