Cancel button on form to bypass required fields

Take a look at the "CancelLib" component available through the "Shared Components" application link to the right... it's under the "Libraries and Utilities" category, and should accomplish what you're looking for.

What does the constant refer to?

I haven't deployed the component myself, but based on the instructions I assume it to mean any constant that you've created on your Appian installation to store the value to save for Cancel buttons which you use across multiple forms. That constant is then referenced when rendering the form (i.e., setting the "value" property of the button), as well as in your workflow (i.e., when the final XOR gateway is evaluated).

if you were to guess, what would be the data type and value for this constant?

While you could technically use a number of Appian data types, I'd recommend Text, using a value of "canceled" or something similarly obvious. This makes your application workflow more readable than obscuring it with another data type (i.e., using the value 0 or 1 to represent the state of the button pressed).

You can set the skipValidation parameter to true() in a!buttonWidgetSubmit. This will bypass the required fields and submit the form.

You want to submit the form even if the user clicks on cancel button?

This is the straight forward way to skip the form validations

You can use a!buttonWidgetSubmit and mention skipValidation:true() so that the form will get submitted even after it requires some mandatory fields to be populated.

Hi Vamshi, Are you sure this works in Process model start form?
