Hello,
We have a requirement to provide custom validation on submit button click on shoppingCart page in Procurement application (Fusion Cloud). We tried extending the application with visual builder and in the shoppingcart page there is a base app provided listenable event preSubmitValidationsEvent. On that event we created and event listener and an action chain. preSubmitValidationsEvent is said to be invoked when the user clicks on the submit button in the shopping cart. However ,when we run the application , no such event is being called on the submit button. Could anyone please help how we can extend the listenable events provided by the base app ?
