Re: AR - issue with removing an item from a HasMany relation
In one application, I associate user accounts with computers based on usage of the computer. I have to both access the computers from the accounts and vice versa in many places in my code. Therefore I took the way to make it bidirectional using Add/Remove-Methods to assure that the association is really valid from both sides. In the same application, I have installation data mapped to computers. It turns out that the computers are almost never asked for the installations (there are separate software-computer and software-installation associations) so this is a unidirectional association from installation to computer. Because it is a many-to-one association, I could omit any special code and simply left it as a public property. -Markus 2009/1/12 Mark Jensen don...@gmail.com: haha, yeah :P but do you have an example when this could be relevant :) On Jan 12, 3:59 pm, Markus Zywitza markus.zywi...@gmail.com wrote: So when would you consider to use bidirectional association ?

Service override keys
Hi,
Could someone clarify what I'm doing wrong here? As an example
consider 2 dummy classes:
internal class MyClass
{
private readonly int myParam;
public MyClass(int myParam)
{
this.myParam = myParam;
}
public int MyParam
{ get { return this.myParam; } }
}
internal class MyClass2
{
private readonly MyClass myParam2;
public MyClass2(MyClass myParam2)
{
this.myParam2 = myParam2;
}
public MyClass MyParam2
{ get { return this.myParam2; } }
}
I register them via XML:
component
id=MyClassA type=CastleScratch.MyClass, CastleScratch
lifestyle=transient
parameters
MyParam5/MyParam
/parameters
/component
component
id=MyClassB type=CastleScratch.MyClass2, CastleScratch
lifestyle=transient
parameters
MyParam2${MyClassA}/MyParam2
/parameters
/component
Now I resolve:
MyClass2 t = IoC.ResolveMyClass2(MyClassB, new { myParam2 = new
MyClass(7)});
But t.MyParam2.MyParam==5. Why the override fails, or what I'm
missing?
Felix.

Re: Is Castle project still alived and stable?
I use the full Castle stack at work and for personal projects. I can't name clients, but some of the largest brands in the world are using Castle to power their web applications (I know that because I worked on them). I've been using the Castle Project for a number of years and along with NHibernate it is right at the top of the .NET OSS world. See http://andypike.wordpress.com for some of my articles related to Castle Cheers On Jan 12, 6:13 am, floyd floyd...@gmail.com wrote: Hi all, The official release is RC-3 on 2007.

Re: Refresh with transient objects (nHibernate + ActiveRecord)
That's a very interesting problem you are addressing. I will tell what we did in ou desktop app. Maybe this will give you an overview of how different people use Castle.ActiveRecord and NHibernate to achieve their goals. I don't say the below approach is brilliant or even satisfactory, but it does reach it indeded purpose. So yes, business value is delivered :) Our app is performing all operations in memory + we use (already deprecated) NHIbernate.Generics library so that both ends of association would contain correct data. Say we have this use case: 1) User want to create new parent object. A parent form is opened. 2) parent editing form has also a tab, where we display a list of all childs it has 3) user wants to add new child, so he opens child editing form 4) user presses save on child editing form. form closes 5) parent form now shows one child in tab 6) user click on cancel button in parent form, and cancels all changes What is happening under the hood in our app is: 1) we have a list of where we store all still to be applied operations on the database. So to this list we add single operation - save to databse our newly created parent, but yet not commit this. 3) a new child object is created in memory (just plain object) 4) a relationship is made from childto parent. for ex. child.Parent = myParent. Now parent.ChildCollection contains one item, which is not yet saved to databse. This is happening with the help of NHibernate.Generics All database operations from child editing form are appended to database operations from parent editing form. Now there are two operations - both are save to database. Firs operation saves parent, second - child. 6) when cancel is pressed, operations on databse are not applied. All relationship changes made in memory are rolled backed. In this case, child.Parent is set again to null. This rollbacking makes possible to construct any-level of undo mechanism. With this approach it is possible to work for one hour with an object and then cancel any level of changes you made to the system. 2009/1/13 Greg Burri greg.bu...@gmail.com Hi, I use nHibernate with ActiveRecord in a such manner : * I have a global session of type 'TransactionScope' * When the user want to save his work his click on file - save of the application menu. This action will execute a such code : globalSession.VoteCommit(); globalSession.Dispose(); globalSession = new TransactionScope(); Basically I have a dialog to edit an object 'p' of class 'Parent' which owns some objects 'c' of class 'Child'. Both of theses classes deriving from 'ActiveRecordLinqBase'. When the user choose 'Cancel' from the dialog after editing some values of 'a' and adding or removing some B objects I want to reverse theses changes (that is remove 'Child' objects that was added and add removed 'Child' objects). (Case 1) If I use the method p.Refresh() there will be an exception like No row with the given identifier exists[Child#0] in the case the user added some 'c'. (Case 2) If I use a transaction with p.SaveAndFlush() + t.VoteRollBack() + t.Dispose() then this error will be throwed : Illegal attempt to associate a collection with two open sessions (for the same case above, where a 'b' is added). Is my approach is good ? Or it's a misusing of nHibernate and ActiveRecord ? I have uploaded a little sample project here : http://www.gburri.org/bordel/ActiveRecordLifecycle.zip. If you want to run it you need PostgreSQL or change the 'app.config'. This sample will create a parent and some children attached to it at launch. You can edit the 'Parent' object and change its state with the button Change state and try to undo the modifications with Cancel. Here are some additional information about my configuration : nHibernate version: 2.1.0.1001 Active record version: 1.0.3.0 Database: PostgreSQL 8.3 Thanks in advance. /Greg -- Darius Damalakas --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Castle Project Users group.

Re: Is Castle project still alived and stable?
Yes, some of us have the requirement to use only released software in our live applications. Sure, development can use code we build locally out of a repository, but that's not accepted when we release to QA and Production. Any updates on release dates would be greatly appreciated.
