The internal format of the object library storage has been updated providing better performance and reduced memory use.

CLOSED ISSUE: Namespaces not being added (Multidimensional arrays bug)

DiegoCanepa — Tue, 23 Jun 2009 15:44:25 GMT

Multidimensional arrays cause an error when the persistence model designer performs reflection on added assemblies.
Please.

Just download and overwrite the AssemblyMapper.dll file.

Karvonite is working great!

I have yet to test perfomance with some of my larger data structures, but as of last night I can save and load a Dictionary of tweakable variables used in my game on the XBOX 360.

Thank you for all of your help.

Kevin

Great!
I'll post the patched dll tomorrow.

Nevermind I figured it out. I was trying to persiste just the field which was the driver list. I needed to add the whole object to the object space.

This was just a test and so I wanted to just try something quickly and so I got confuselled ;-)

It seems to work fine for saving! Now to try loading it back! :-)

Thank you very much, the model designer is working now.

I guess I won't be persisting 2D arrays then! :-) I was more concerned about just being able to have them in my classes.

Also, my assemblies aren't giving me any trouble, neither when I compile nor (anymore) when I load them into the model designer, so I'm not sure what the problem is with my references.

And.... persisting a generic List and/or a 1D array isn't working! :-) D-oh!

Here is the error message:
The type of the supplied object is not defined as a persistent class in the persistence model.
Parameter name: item

I have a class called Driver. When I save one Driver object there is no problem. I have another class which contains a List of Drivers (or array neither work). When I try to save the member field which is the List of Drivers it gives me this error message. The member driverList has been set up in the persitence model.

Any ideas?

Thanks again!
Kevin

Hi,
Please check the following link to ensure that I'm using the correct assemblies:

Hi,
Single dimensional arrays are fully supported.

Karvonite can automatically save any field or property whose type implements System.Collections.IList and System.Collections.Generic.ICollection(T) generic interface where T must be an enumeration type, a predefined type or any class or structure defined in the persistence model. This also includes single-dimensional arrays.

Jagged arrays are not supported as they do not comply with the above persistence rules. But it no means that you cannot use jagged arrays or multidimensional arrays in your code. They cannot be persisted only. Actually, you are not seeing other classes due to the persistence model bug. I'll post a single dll with the bug fix.

Although before I spend any more time trying to convert my code... are you unable to have multidimensional arrays anywhere in any class in your code? None of my classes show up in the model designer, but not all of them have 2D arrays... If you can`t even have one multidimensional array in your entire assembly then this really isn`t going to be useful for me.

The 2D arrays could be recreated when the object loads, although it will make the persistance interface a lot less simple.

Does the bug apply to jagged arrays as well or strictly to "multi-dimensional" arrays in the strict C# sense?

I am going to try and see what happens if I get rid of the 2D arrays. Converting all of my 2D arrays to single dimensional arrays is probably not worth the effort. Converting to jagged arrays I can do!

Multidimensional arrays cause an error while the persistence model designer performs reflection.

Hi!
Do you need to persist 2d arrays? Or you are just using them without the need to persist them?
Ok, let me investigate a bit more. The 3 assembly files you sent are enough for creating a peristence model.

kasmeltz — Mon, 22 Jun 2009 16:38:05 GMT

Ok thank you!

I read in the discussions that there was a problem with 2D arrays but then I thought I read that it was fixed.

What about a jagged array is that also a problem? I really don't want to have to convert my 2D arrays to flat arrays because it will mean changing tested and stable code and possibly introducing bugs. But converting from a 2D array to a jagged array would be a little easier and hopefully safer.

What do you mean by manifest version? I recompiled the entire project and sent you the .exe and .dll files exactly as they had been created. It compiles fine in VC# 2008
without any assembly warnings or etc. I can't send you ALL of the files being used by my app because there is 800+MB of content.

Thanks again for your help I really hope I can get this to work.

Hi,
There's still a bug in the persistence model designer when a type contains a two dimensional array. It's supposed to be fixed, but it is not.
We'll post a SP3.

On the other side, there is an additional problem as one of the assemblies has a different manifest version. Just be sure to send me all files being used by your app to test it again.

Just rebuild your project and send me the compiled exe/dll files to create a model. Doesn't matter if your are using Karvonite. It is not a requisite.

kasmeltz — Fri, 19 Jun 2009 14:25:35 GMT

Ok thanks I wasn't sure.

I will send this to you when I get home from work.

I am using XNA Framework 3.1 do you think that would cause a problem?

Also I wasn't entirely sure of what to configure everything (the documentation is pretty sparse)

Do you need to reference the Karvonite.dll in your project and recompile before you use the assembly in the GUI?

Hi,
I've received the attach. However, I need all referenced assemblies too. I still need the NewWorldLibrary31.dll i order to check the problems.
