NEW POST: failing to load - beginners question

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 =)

NEW POST: New Persistence Model Editor Features

DiegoHernanCanepa — Mon, 09 Nov 2009 17:53:59 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 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.

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!

Hi,
Workaround, try this:

private Dictionary<int, string> testDict = new Dictionary<int, string>();

public Dictionary<int, string> TestDict
{
get { return testDict; }
set { testDict = value; }
}

Any news on that update? I do not see a new build on the downloads tab.

Does anybody have any ideas? It's been a couple days now and I'm kind of stuck. :)

NEW POST: serialization issue

jdsmith2816 — Fri, 09 Oct 2009 15:53:01 GMT

I set up a very simple test case this morning that does not work either.. In the example code below I simply left the deserializatin commented.. ran the code to create and add the testClass.. commented out that code the uncommented the deserialization.. and inside of the returned testClass the testDict was null.

public class TestClass
{
public TestClass()
{
}

public Dictionary<int, string> TestDict { get; set; }
}

if (!File.Exists(@"d:\test.dat")) {
_os.CreateObjectLibrary(ExistingFileAction.DoNotOverwrite);
}

_os.Open();

/*
var testClass = new TestClass();
testClass.TestDict = new Dictionary<int, string>();
testClass.TestDict0 = "omg";
_os.Add(testClass);
_os.SaveAndClose();
*/

var testClass = _os.OfType<TestClass>().First();

I switched over to a standard Dictionary and I'm still showing the _tiles dictionary as null upon deserialization. I did confirm that, at the time of calling _os.Add(level); and _os.Save(); that the _tiles dictionary most definately as populated.

NEW POST: serialization issue

jdsmith2816 — Fri, 09 Oct 2009 07:19:21 GMT

Greetings again!

I'm trying to serialize my level structure. Currently my Level class contains a private SerializableDictionary<int, LevelSquare> _tiles; this is failing to serialize/deserialize.

SerializableDictionary is simply a dictionary that implements IXmlSerializable which allows the standard serialization/deserialization functions in .Net to work on it.

LevelSquare is a very simple class containing two shorts, one string, and one bool.

Upon de-serialization the _tiles member of my Level class is coming back with a null exception when I inspect it after breaking directly following the load process. What am I doing wrong?

Now that I'm using Karvonite I guess it no longer needs to be a SerializableDictionary so I'll try switching that back to a standard Dictionary but I don't think that's the problem?

NEW POST: usage question

DiegoHernanCanepa — Thu, 08 Oct 2009 17:35:26 GMT

Multidimensional arrays are not supported. All supported types are explained in the Karvonite Overview documentation document.

NEW POST: usage question

jdsmith2816 — Thu, 08 Oct 2009 03:36:21 GMT

Are multidimensional arrays such as ,, serializable with your product or does it have the same limitations on serialization as the standard xml serializers?

NEW POST: usage question

DiegoHernanCanepa — Thu, 08 Oct 2009 03:23:10 GMT

Keep all your objects in just one file and saves in separate files.

jdsmith2816 — Thu, 08 Oct 2009 03:18:34 GMT

What sort of info? I've never looked at this before today so I'm a bit short on experience here. :)
