Error being thrown when using openaccessdatasource on webpage (with gridview displaying data)

[Peter]

This problem (and related issues) is already being looked into by Telerik through a support ticket, but as my delay is now already up to 2 weeks, I am seeing whether someone out there has had the same problem and resolved it.

I have a rlinq which exposed some flaws in the visual designer (fixed in the last build). When I make a webpage with an openaccess datasource that tries to retrieve data, I get the following error. Has anyone encountered this / attempted to solve this?

Thanks, much appreciated.

Hi Peter Huisman,

 This error can be thrown when there is an inconsistency in the version of the OpenAccess assemblies. For example you could have one version of the product installed, but some of our dll's with another version is present in your bin folder and gets loaded in the Application Domain. It usually happens when there is a difference between the versions of Telerik.OpenAccess.dll and Telerik.OpenAccess.35.Extensions.dll. I hope this provides useful for you as well as anyone in the community that might encounter this issue. On our side, we will try to provide an error earlier in the stack which points to the user what exactly is the issue as we admit, this exception is actually a side effect and a rather nasty one to trace.

nevermind.

Has anyone has more info regarding this problem?... The only way I make it go away is stopping and resuming the pool, but I have to do this every time I build the project and its becoming annoying. I already check the ORM references and versions and they are correct. 

Thanks

Hello Guillermo,

I would like to ask you about more information regarding when this problem is actually happening on your side. You mentioned that it happens when you rebuild your project, does it also mean that you are upgrading the OpenAccess assemblies to newer version, or is it just adding new functionality to your application and rebuilding, without upgrading OpenAccess? Also, what is the version of OpenAccess that you are using currently?

I have same problem with new version and it happen almost always when my application pool is new. After few seconds it start work again:

Application id class 'Telerik.OpenAccess.RT.OID.IntIdentity' must have field: 'public System.Int32 _id'

Hello,

After some private communication it turned out that the error Mikko was getting was caused by an OpenAccess assembly with older version in one of the bin folders of his project. This is the most common cause for this problem, so if anyone else sees the same error, now he knows where to look at.

Kind regards,

I cleaned all files in my bin folder and my problem solved.

[Steven Picard]

I recently inherited an ASP.NET app that uses Open Access. Although I generally use Telerik controls I have never used Open Access. I am getting the same error as above. Everything compiles and runs fine. This error only happens when I save. I have verified all versions are correct and that I have cleaned the project numerous time (so there are no outdated or conflicting DLL's.) This project worked for the other two developers (who are no longer here) and I have not modified their code related to this in any way.

Application id class 'Telerik.OpenAccess.RT.OID.IntIdentity' used by class 'XXX' must have field: 'public System.Int32 _XXX'.

Any ideas? This is really holding me up.

Thanks.

Hello Steven,

For the moment the only known reason for this error is the mismatch of OpenAccess assemblies in the bin folder. You said that you have already checked this, so it is possible that the problem is different in your case.
It would be best if you could send us a support ticket and attach there your project, so we could look into it. This would be the fastest way to reproduce the problem and find a solution.
