How to Extract Custom Field Values from NetSuite Web Services CustomFieldList?
This guide explains how to programmatically identify and retrieve specific custom field values from a CustomFieldList object returned by NetSuite web services using Java.
Short answer
To retrieve a custom field's value from a CustomFieldList in NetSuite web services, use the instanceof operator to determine the field type. Then, cast the field to its specific type and verify its internal ID to access the correct value programmatically.
Scenario
When integrating with NetSuite via web services, developers often encounter CustomFieldList objects containing various custom fields. The challenge lies in efficiently identifying and extracting the value of a specific custom field from this generic list, as field types are not directly apparent.
Solution
The solution involves iterating through the CustomFieldList and using the instanceof Java operator to determine the specific type of each custom field. Once the type is identified, the field can be cast to its particular class, allowing access to its value by verifying its internal ID.For example, to retrieve a LongCustomFieldRef with the internal ID "custitem_guru_timestamp", the following Java code snippet can be used:
for (int i 0; i < item.getCustomFieldList().getCustomField().length; i++){if (item.getCustomFieldList().getCustomField(i) instanceofLongCustomFieldRef){ LongCustomFieldRef field(LongCustomFieldRef)item.getCustomFieldList().getCustomField(i);if(field.getInternalId().equalsIgnoreCase("custitem_guru_timestamp")){timestamp field.getValue(); } } }This approach ensures that the correct field type is handled, and the desired value is extracted accurately.
