IDEMPIERE-5126 Virtual column lazy loading (#1095)
* IDEMPIERE-5126 Virtual column lazy loading Virtual columns are now loaded only whenever their respective getters are invoked. This functionality works irrespective of the PO constructor used. Query class now uses lazy loading by default as well. * IDEMPIERE-5126 Virtual column lazy loading Have the model generator ignore virtual columns with the @SQL prefix, as their generated getters would always return null. * IDEMPIERE-5126 Virtual column lazy loading Added quoting to virtual column names * IDEMPIERE-5126 Virtual column lazy loading Reload virtual columns if the record was reloaded. * IDEMPIERE-5126 Virtual column lazy loading Fixed class cast exception in unit test. * IDEMPIERE-5126 Virtual column lazy loading Support for loading selected virtual columns along with regular table columns, skipping lazy loading. * IDEMPIERE-5126 Virtual column lazy loading Fine-grained virtual column loading support for Query. * IDEMPIERE-5126 Virtual column lazy loading Support for loading selected virtual columns along with regular table columns, skipping lazy loading. * IDEMPIERE-5126 Virtual column lazy loading Improved support for the constructor PO.PO(Properties, int, String, String...). * IDEMPIERE-5126 Virtual column lazy loading Refactoring. Reduced size of messages sent and received from database engine when lazy loading virtual columns. Other minor changes. * IDEMPIERE-5126 Virtual column lazy loading Added testing assertions. * IDEMPIERE-5126 Virtual column lazy loading Silenced Eclipse warnings.
