I am using the startprocesswriter function in a bind and I can not get it to work with Appian 7.6 or 7.7. It is always making it to the List of Variant portion of code in the plugin. Below is my sail code trying to use the plugin.

a!sectionLayout(
label: "Lorem Ipsum",

get: local!dontShowAgain,
set: fn!startprocesswrite(processModelId: 216, processParamerters: {_, {userName_txt: fn!loggedInUser()}})
),
...
a!checkboxField(
labelPosition: "ADJACENT",
choiceLabels: {"don't show again"},
choiceValues: {false},
value: local!dontShowAgain,
saveInto: {
local!dontShowAgain,
a!save(local!startProcessParam,{showWelcome_bool: local!dontShowAgain})
}
)
