Why does the 'shipaddress' fieldChange fire 4-5 times when changing the selected option in the shipaddresslist of a SalesOrder?

AI generated answer (using internal Slack threads):

The 'shipaddress' fieldChange firing multiple times when changing the selected option in the 'shipaddresslist' of a SalesOrder is likely due to the way NetSuite handles address fields. The 'shipaddress' is a calculated field, created from the address elements in the addressbook entry marked as default shipping. Therefore, any update to that sublist seems to force it to be recalculated, causing the fieldChange to trigger multiple times. This is a default behavior in NetSuite and it's not something that can be changed without scripting. If you have a function that needs to execute on the 'shipaddress' change trigger, you might need to add conditions to your script to ensure it only runs when necessary, to avoid performance issues. Please note that the 'shipaddresslist' field might not always be populated. There is a difference between the internal id of the address, and the address internal id. If the 'shipaddresslist' is empty, it's possible that the 'shipaddress' was set directly. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
