  Technically, the ternary operator suggests there are only two possible conditions. You define a predicate, the consequent, and the ONLY alternative. If there were more than one alternative, you would wish to use a switch-case or if-else. Your approach could become unwieldy if new logic was introduce... read more »

  John, Can you show how your ORM Object properties reference the preInsert() and preUpdate() methods? This is a problem I was thinking about this morning, without a solution, so your post couldn't have come at a better time. Best, David... read more »

  @Justice, I'm looking at the Stub Generator from Adobe, and in their Beta stub generator, the 'event' parameter it generates (specific to my project) is type-casted to an "Event" (schedules, owner, ID, etc). Then, Adobe's stub generator is calling EntitySave(event) for both Update and Create Opera... read more »

  You can omit all of the setters and just save a strongly typed Entity, too. So in my case, I'm just updating two properties on the server, and the client-side is updating the other 100 updated properties. I pass in the object already modified from the client, and all I write in CF for a Create or U... read more »

  @Hatem, Looking at the current project I am rebuilding in CF9, the knowledge portion of the equation, with regard to 'writing better code', is the improvement in the use of abstract classes for security, and the addition of more strongly typed objects. The use of Hibernate ORM in CF9 has allowed m... read more »

  @Justice, I'll do it. I need a couple of days to finish cleaning up the login script, and it would eat up most of Ben's database volume if I posted the related methods (and their SQL), but if I post the old Login versus the new Login with the ORM script, the differences should be apparent. I'd fe... read more »

  @Justice, It is magical. I "finished" rebuilding my user login last night using Hibernate, and to make a single Hibernate request to retrieve all of the same information that once took 1000+ lines of functions and SQL absolutely astounded me. It's a scary time to be a DBA.... read more »

  @Ben,@ Justice In Hibernate, if I run a query to retrieve a specific User() object using ORMExecuteQuery(), I successfully get back all of the object properties. I want to return the entire object to my client (Flex). Some of those properties, like the "uPassword", I want to eliminate from the re... read more »

  For the record: "ColdFusion will automatically save any changes made to a persisted object at the end of the request regardless of whether you call EntitySave or not. You can override this behaviour by adding this line to Application.cfc this.ormsettings.flushatrequestend = false;" Then, you hav... read more »

  Can preUpdate be called with an abort/return to prevent the ORM from updating? For example, a user is trying to update a record he does not own, so I want to bail out of the update. What's the best way to handle this?... read more »
