How can I set a not mandatory file upload widget?

Hello,

I have set FALSE IN the property required in a file upload widget but when I run the process and let the widget empty I get the next error:

INFORMACIÓN: org.restlet.Component.BonitaRestletApplication Error while validating expected inputs
Explanations:
{} cannot be assigned to FILE

I have found that I need to put null in the definition of the json variable. When I press the submit button apparently the form is submitted but the process do not continue to the next actor and I cannot do anything else because the process seems to be in a kind of limbo.

Please, can you help me with that.?

Thanks in advance.

Regards

Geovanny C.

In your return function you need to specify an if statement something as follows:

return { fileUploaded(filename); }

function fileUploaded(filename){
if (filename!==null){ return filename }
else{return null}
}

Thanks for your response Sean.

I got the idea but I don´t know how to implement it in my task.

The forminput variable of my task have the next information (JSON):
{
"registrarCeseFuncionesInput" : {
"informeValidado" : false,
"regresarA" : "Seleccione una opción"
},
"informeRecursosHumanosDocumentInput" : { }
}
where informeRecursosHumanosDocumentInput is the variable of the document.
The formouput variable of my task have the next information (JavaScript Expression)

return {
'registrarCeseFuncionesInput': $data.formInput.registrarCeseFuncionesInput,
'informeRecursosHumanosDocumentInput': $data.formInput.informeRecursosHumanosDocumentInput
};

and this is my form:

How could I implement your code in my variables?

Thanks in advance.

Regards.
