We are getting massively different results on field loading between explicit post-compile enhancement and automatic run- time enhancement. Testing exactly where and when the results are different for our demo web app is a very time consuming task, and very difficult, it means testing literally 100s

As mentioned elsewhere, subqueries are not currently supported.  A subquery is the way that seems recommended to get only the latest entry in a time series (e.g. the latest time -clock entry for all employees).   Is there an ObjectDB way to get the latest entry in a series? 

I have an entity library which I have integrated build time enhancement in.  The enhancer reports it has processed all of my persistent classes.  When I attempt to run a Bootstrap process with this library I get the error shown below.  The entity referenced in the error (Terms
