Call a process model using a button, is it possible?

You are aware of

https://docs.appian.com/suite/help/20.4/Start_Process_Smart_Service.html#a!startprocess()

Hi Stefan,

I tried below syntax, could you please help with syntax to start process mmodel using button?

a!startProcess(
processModel:cons!PM_TESTPTS,
processParameters:{},
onSuccess :"Ok",
onError :"Not Found"
)

And

a!buttonWidget:{

value:a!startProcess()

}

Thanks,

Deepak

Following https://docs.appian.com/suite/help/21.1/Start_Process_Smart_Service.html#a!startprocess()

you will end with something like:

a!buttonWidget(
  saveInto: a!startProcess(
    .
    .
  )
)

If you're wanting the user to flow into a task in the process instance you're starting from this action, you must use a link and a!startProcessLink.  A button can not do this.  However if you're just trying to kick off a process that runs in the background, you can use a!startProcess (as pointed out already by Stefan) in either a button OR a (Dynamic) Link, basically interchangeably.  You haven't really clarified what your use case and desired User Experiences are.

Hi Stefan,

The above syntax i tried its not working, could you please test sample code and give me syntax? 

Thanks,

Deepak

Please paste what you tried and I will have a look. Also I need to know what the actual error was.

This is my syntax but not getting any error,

a!formLayout(
buttons: a!buttonLayout(
primaryButtons: {
a!buttonWidget(
label: "Create New Ticket",
value:"",
saveInto: a!startProcess(
processModel:cons!PM_TESTPTS,
processParameters:"",
onSuccess :"Ok",
onError :"Not Found"
) ) }
) )

OK. Please check the documentation for the type of each parameter.

processParameters must be a dictionary but not an empty string

onSuccess and onError must be null or a list of a!save() but not just a string.
