How can I capture data from a form using an "anonymous" user?

I require that through a form (or in its default an application / widget) a couple of data can be captured but from an unidentified user. It is as if it were a public form that records data from an anonymous user and then processed in some flow with human tasks. Is anonymous authentication or automatic default login possible to capture information?

Thanks for the help.

How to change an input field's error message


I am looking for a way to change an input field's default error message, since by default they are in English and I need them in Spanish. I have tried changing the language of the portal, web applications and the studio itself, as well as attempting to add 'custom' error messages in a custom widget, all to no success.

Any help would be greatly appreciated.

Form data not passed to business variable

Hello All,

My process have a simple business object / variable. I have created a simple script that returns the new instance with the default values for the mandatory fields.

I have created an instantiation form with a simple text field, according to the contract defined for the instantiation step (object.attribute), but the value is never passed to the business variable. It's like the variables is instantiated AFTER the form as been invoked and submitted.

If I take a loot at the database, I see the default data returned in my script.
