Hey all, seem to have an issue atm, on beforeload I want to set a sublist value:
cRecord.setSublistValue({
                                sublistId: 'item',
                                fieldId: 'custcol_wrx_ci_htn',
                                line: i,
                                value: itemRec.getValue({fieldId: 'custitem14'})
                            });
cRecord is: var cRecord  = scriptContext.newRecord

Everything flows, no errors and if I dump the value to the log it shows correctly however when the record loads the value is still not set.  Do I need to commit the line or something?  I usually work with this on the client side.

For archive purposes, you can not interact with a new record on before load from a user event script per the documentation.  All changes will be ignored.  You can use workflows however to set field values before a record loads, which is faster than pageinit client side when loading other records.
