Hi,
XNA 3.1 is not yet supported. This might be the problem as the XNA version of Karvonite is compiled againste XNA 3.0.

Hey,
I just found out it was working fine when i didnt add any objects to the ObjectSpace.
I am using XNA 3.1 for Windows.
This is the complete exception (the inner exception: The ObjectSpace is closed.):

If you say now it's not something completly obvious I'll send you my project.

By the way, you're providing some very good support here!

Hi,
Could you send a sample so we have something to test the exception?
A Karvonite 4.0 beta will be available soon. Are you using XNA for Windows? or the Xbox?

Regards

Oh, tested it, but obviously it doesn't make any difference... still the same error.
Could this maybe be due to some incompabilties, or maybe due to a flawy Persistence Model?
The object space saving seems to be working, the file is there and it's filled with data.
I don't know where to start searching since the exception is a very low level one...

I think you are using "/" instead of "\".

Hello there.
I recently downloaded Karvonite and tried to implement it in my little XNA game project.
I created a Persistence Model and set up the ObjectSpace object, I think it's working (At least I don't get any errors...).
But when trying to load an libary, I get this exception message: Exception has been thrown by the target of an invocation.

Here's what I've got:

creating the ObjectSpace

objectSpace = new ObjectSpace(modelSource, "Content/ObjectModel");
objectSpace.CreateObjectLibrary(ExistingFileAction.Overwrite);
objectSpace.Open();

I got some GameObject objects which are to be serialized
In their constructor:

objectSpace.Add(this);

Now these are the save and load methods

public void Open()
{
objectSpace.Close();
objectSpace = new ObjectSpace(modelSource, "Content/ObjectModel");
objectSpace.Open();//Exception has been thrown by the target of an invocation.
}

public void Save()
{
objectSpace.Save();
}

Is there anything wrong you see? Should I provide additional information?

Thanks in forward and thanks for this nice product =)

CLOSED FEATURE: New Persistence Model Editor

DiegoHernanCanepa — Wed, 18 Nov 2009 02:20:35 GMT

We've a new Persistence Model Editor in the oven (former Persistence Model Designer). The new version will be released as part of the December 2009 release. A beta version just for testing and feedback purposes might be released soon.

*Here is a list of the new features:*

* New Name: Persistence Model Editor (former Persistence Model Designer).
* New UI experience. We've a new look and feel: simpler and more intuitive. Less is more.
* Improved Undo/Redo system.
* Quickly find model elements using the new search box.
* The new Add Types and Members functionality lets you add element faster. No more right clicks, no more Batch Add.
* Errors can be easily visualized in the tree view. An automatic error list shows or hide as model changes.
* Multiplatform support. Now you can choose several platforms (Windows, .NET CF and Xbox360) and maintain just one model file.
* Model navigation.

Overview
Karvonite is an object persistence framework for the .NET platform. Karvonite's goal is to relieve the developer from all serialization related programming tasks in a non-invasive way. It can save you from writing a lot of boring and thus error-prone code for moving the in-memory objects to and from the data storage. The Karvonite API is very simple and provides a gradual learning curve with a very low entry point.

Despite the fact that .NET serialization and XML files are ideal for storing data easily and effectively, in several cases they are not a viable replacement for a data engine. In contrast, not all applications require the horsepower and the excessive functionality and optimization of an enterprise database or a SQL engine; databases are a skill unto themselves and the learning curve is not as fast as expected.

Karvonite April (CTP 2009) SP2 now available

Hi,
This is something we are willing to resolve but it is not easy. Anyway, we'll found a solution ;-)

Hi,
I just ran into the same problem.
Is there an easier workaround than creating a new model yet ?

Except for this issue karvonite has been a dream to use,
Thanks!
