Do we have an option to invoke a process model from SAIL Code?

The Start Process Writer Shared Component should help you with that.

Yes.. We can invoke a process model from the SAIL using the function 'startprocesswrite' with the 'bind' function

Eg: local!invokeProcess:bind(
{
valueToBePassedToProcess:null
},
startprocesswrite(
processModelId: ## /* Process Model Id of the process that has to be invoked */,
processParameters: _
)
)

You can use this local variable(local!invokeProcess) to invoke the process model from the SAIL. Say you want to pass a 'Name' field from the SAIL to the process model on clicking a button, the sample code will be like below :

a!buttonWidget(
label: "Submit",
style: "PRIMARY",
value: {
valueToBePassedToProcess:ri!name
},
saveInto: {
local!invokeProcess << _,

)

Thank you Alok and Siddharth, I will give it a try.

Note: the model will be invoked asynchronously and will not pass you back any results. If you're needing to get output you can, for example. get it to create asynchronous content e.g. a Task or an email.

I'd note that even though the process fires asynchronously, my tests have revealed that if the process is set to chain through, then any DB updates it performs will be done before the SAIL form's With() parameters (if any) are reloaded.

I have successfully used this trick to create, for example, a "star" icon on a Record dashboard which is actually a graphic link, which when clicked, adds a bookmark row in the DB for that user/record pair, and the form updates in realtime with a filled-in star to indicate "bookmarked". Again, it *is* dependent on process chaining, at least per my tests.

+1 for this neat chaining trick!
