Rendering integer as picklist.

Is the field required? You can only eliminate the “–None–” option if the field is NOT required, otherwise it would be impossible for a user to leave the field blank. If the field IS required, then you can eliminate the --None-- option by using the following option:

field.options.addNoneOption = false;

Whenever you’re setting picklist field entries, value needs to be a string, not a number, same thing for for field.metadata.defaultValue.

FYI, the purpose of the defaultValue property on field metadata is to specify a value to insert into this field when creating a new record of the given object– the field.metadata.defaultValue property is not used after a record is first saved. 

Zach,

Thanks for the thorough explanation!
My renderer is working, even though I’m giving it numbers instead of strings. The field isn’t required, but it makes sense to make it required (at least in the ui, if not salesforce).

One quick additional question:

What does the ‘defaultValue’ in the definition of a picklist entry do (in bold below)?

field.metadata.picklistEntries = [
       { value: 30, label: ‘30 minutes’, defaultValue: false, active: true },
       { value: 60, label: ‘60 minutes’, defaultValue: true, active: true }
];

Currently, nothing.

ha. ok.

OK. So what does “active:true” do?  What happens with “active:false”? 

Doesn’t seem to change anything for me.
