process model in section layout in Navigation(collapsible)

{
a!sectionLayout(
label: "PrimaryDetails",
contents: {
a!linkField(
links: a!startProcessLink(
label: "update form",
processModel:cons!AV_START_PROCESS_LINK,



bannerMessage: "used to update the existed person details"
)
)
},
isCollapsible: true,
isInitiallyCollapsed: true
)
}

we have to create a constant for the existed process model and by using the a! start process link. or a! start process function we can directly take an action for the new record from the interface. there is a small difference between the above functions that is a! start process link-Start the process Synchronously & a! start process function -  start the process asynchronously.

 i am using navigation which is collapsible  my issue is i'm calling different interface on navigation interface on click of each navigation when i call the interface by rule! it works perfectly on text click and also after collapsing but when i use process model to call the interface it works on text click not on icon click after collapse its just shows blank and do not shows any error

Thanks for clarification Richa. Did you check the link? when its gettting called via process model.

Richa to help you better, is it possible to get the code atleast from process model side. Like, as per my understanding you are calling the same interface in the user input task right?
