I have a user event on beforeLoad, I want to disable a field on the screen, I'm not sure exactly how to do it . I think it's something like this .updateDisplayType({displayType: ui.FieldDisplayType.INLINE} Any idea ?

updateDisplayType({displayType: serverWidget.FieldDisplayType.DISABLED});

yes but I have to pass the field. I'm trying to disable the field memo, Where do I put memo in this ? memo.updateDisplayType({displayType: serverWidget.FieldDisplayType.DISABLED}); ????

context.form.getField({id: ‘memo’}).updateDisplayType({displayType: serverWidget.FieldDisplayType.DISABLED});

Looking good. LEt me try

lots of documentation and examples in SuiteAnswers
