I have 1 custom object that I deploy via Change Sets.
Result: Deployment Status page, component count = 1
I deploy same custom object via ANT
Result: Deployment Status page, component count = 17
Here's the kicker... My custom object has:
15 Custom fields
1 CurrencyIsoCode field
1 Owner field
1 Page Layout
No validation rules, field sets, buttons/links etc., no record types, no apex sharing reasons etc..
I presume that Salesforce is counting the custom fields + currencyIsoCode field + object information as distinct components. Has anybody else found this/seen/received an explanation on this from SFDC?
