is there any way to display errors nicely when they occur on a record/transaction? Say you are validating in beforeSubmit and need to prevent the save operation, you throw an error and the NS output is the stringified error object… not exactly user friendly.

You can print error.code and error.message. Instead of printing the error ?

i need to “throw” the error in order to keep the system from saving the record. then, I am stuck and at Netsuite’s mercy to display correctly; which they don’t - they simply print the error object. In a perfect world, I would let NS know not to save, then redirect to the record passing a parameter that I can then display how i would like in a N/ui/message WARNING or ERROR

You could use a client scripts saveRecord function paird with the N/ui/dialog module to throw a popup on the screen with your message. Then return false out of the saveRecord function to prevent the save from occurring

100%. But, that’s client side. Imagine I’m on an Item Fulfillment (this is the scenario, actually) and the user is clicking the Marked as Shipped button…

hmmm interesting problem. Maybe a beforeSubmit that validates and redirects the page back to the IF screen if the criteria isnt met

that’s the “throw” in the beforeSubmit function

Ah yeah the native buttons are always difficult to deal with. Maybe you could hide the button like you said with a beforeLoad and use the message module to put a banner at the top of the screen alerting the user why its hidden

Throw and don't catch your chosen text. It won't be "pretty" but it will be plain text and not have some user unfriendly stringified object displayed.
