ObjectProvider Error

[Tajes]

I still couldn't try OpenAccess ORM because I get an error when I try to insert a ObjectProvider in a WinForm. Always the same error:
      " Failed to create component 'ObjectProvider'. The error message follows:
        'System.Runtime.Serialization.SerializationException: Type
       'Telerik.OpenAccess.Sdk.Addin.Model.VAProject' in Assembly
       'Telerik.OpenAccess.SDK.AddIn, Version=2010.1.312.2, Culture=neutral,
       PublicKeyToken=7ce17eeaf1d59342' is not marked as serielizable.

I'm using MySql database and I've followed step by step the OpenAccess-MadeEasy.pdf instructions.
I'm also using visual studio 2010 RC and the Trial Telerik's ORM.

I don't what to do else.
Can somebody help me?
Is there another way to use the objectProvider without using the visual form editor?
thanks.

Hi Iván Tajes,

This looks like an installation problem. You can try installing the latest internal build (version 2010.1.414.3) which can be downloaded from here. Please before installing the new version, make sure that the previous one is completely uninstalled, sometimes it can happen that two installations are mixed.
Hope that helps.

Hi Damyan Bogoev,
      OK, It don't throw the error now but the ObjectProvider's wizard don't let me choose context provider nor persistant class to continue.
      I've enabled the two projects, one with the persistant class generated by reversing mapping, and the other with the form where I insert the object provider. I've rebuilt the solution. What can I do?
Thanks for your time.

Hi Iván Tajes,

It seems you are close, maybe you are missing some small detail. Please make sure that:
- The Windows Forms project references the project containing the persistent classes;
- When enabling the Windows Forms project enable only the second checkbox (DAL) on page two of the wizard. This will create an object scope provider class which is required by the ObjectProvider wizard. If you have already enabled the project without checking this checkbox, you can re-run the wizard and enable the DAL option this time.
After you rebuild the solution, the ObjectProvider should be able to see the object scope provider.
Hope that helps.

Hi Damyan Bogoev,
     It's all correct. I've one project with the persistent classes, this project is enabled with only the first checkbox (persistent classes), and I've a second project with the winforms, enabled with only the second checkbox (DAL), with a reference to the first project added and the object scope provider created. After rebuilt all projects I still have the same problem. I've repeat all the process a lot of times and I always get the same problem, the objectProvider don't let me choose the object scope provider nor persistent classes to continue.
    Is there any way to set these objectProvider's settings programatically?

Thanks for your time.

[Damyan Bogoev]

Hi Iván Tajes,

You could set the ObjectProvider settings programatically using the following approach:

this.objectProvider1 = new ObjectProvider(this.components);
this.objectProvider1.BaseType = typeof(DataLayer.Product);
this.objectProvider1.ObjectContextProviderTypeName = "TestApp.NorthwindOAProvider, TestApp";
this.objectProvider1.OQLStatement = "SELECT * FROM ProductExtent AS x";


this.objectView1 = new ObjectView(this.components);
this.objectView1.ObjectProvider = this.objectProvider1;
this.objectView1.Position = 0;
this.objectView1.RootType = typeof(DataLayer.Product);

this.dataGridView1.DataSource = this.objectView1;

Hope that helps.

Thank you very much Damyan Bogoev,
    It works. Doing it programatically it works perfectly. I don't now why not with form designer.

greetings Damyan Bogoev.

I've tried again with the new release of WinForms and OpenAccessORM and I still get the same error. I've unistall all components, unistall visual studio 2010 and reinstall all again. Is there anybody with the same issue? or I'm the onlyone?

[Damyan Bogoev]

Hi Iván Tajes,

Could you please check if the Telerik.OpenAccess.Windows assembly is present in the GAC of your development machine? If this is the case, please remove it from there.
In order to reproduce the false behavior we will have to ask you for some additional information:

• What operating system you are using on this machine?
• What version of Visual Studio you are using, maybe it is a localized one? You can check that from the Help | About Microsoft Visual Studio menu. Just click on the Copy Info button and send us this information.

We are looking forward to your response.

Greetings,

Hello,

I still have the same problem with the new Q2'10 release. I don't know what to do. I have tried with differents versions of visual studio.

How can I add a datasource to a Form to manage the bindingSource of controls if I can't add the objectProvider? Must I do it only programatically? I have download the project examples but neither works.

Thanks for your time.

[Tajes]

Help!
I also tried to add a dataform using right click menu in the project but It advise me "The project has no persistent class or is not compiled. Please compile it first to reflect the recent chages". And I have enabled the projects, the first only with persistant classes checkbox enabled, the second only with the DAL checkbox enabled and with the reference to the first project added. I did reverse mapping, update config references, rebuilt all projects, the persistent classes appear in my project but I still get the same error. I tried everything and I don't know what to do.

Thanks.

Hi, I have try the OpenAccess ORM in another machine creating two projects, one for datalayer enabled with persistent classes, and another enabled with DAL for the forms, and when I try to drop the objectProvider from toolbox to the form I get the same error,
System.Runtime.Serialization.SerializationException: The type 'Telerik.OpenAccess.Sdk.Model.VAProject' in assembly 'Telerik.OpenAccess.SDK.AddIn, Version=2010.2.714.1, Culture=neutral, PublicKeyToken=7ce17eeaf1d59342' is not marked as serielizable.

I really need to solve this!
Thanks
