I am trying to reverse map a legacy SQL database with around 700 tables by creating a OA Domain Model (I think this code needs to be looked at for performance on large DB schemas). After several attempts I was finally able to get the .rlinq file created.
However, the code generation will not work for some reason. When I right click on the OA Domain model and choose 'Run Custom Tool' I get the following error...
The custom tool 'MetaModelCodeGenerator' failed. Specified cast is not valid.
Any ideas what might be causing this?
Thanks,
Byron

Hi Byron Blattel,
On some machines the customers experience such a strange behavior, we are still not able to reproduce the exact behavior. My advice to you is that you upgrade to the next version when it is available (I hope tomorrow). We solved really a lot of issues plus we will introduce VS2010 support and I think your problems will not be available in the newer version.
All the best,

HI,
Im just wondering if there has been any update on this problem. I've installed the very latest ORM (2010.1.623.5) and created a Model but hit the "Specified cast is not valid" error.
I've even tried deleting everything from the model and running the custom tool (from the menu), but get the same result.
Interestingly, the project is part of a solution with several other projects. If I open JUST the project in question then it works fine. As part of the solution it wont work, even if I remove all other projects from the solution.
The full error on running the Custom Tool is shown below:
Thanks,

Update: I spoke too soon about opening the project without the rest of the solution. That's now not working either.
As this seems to be related to the template compiler finding the project so it can add the generated code files, I noticed the following:
1) The code is been generated without any problems.
2) On the diagram, clicking Model Settings, then Code Generation > Output, selecting Project Folder and clicking Browse results in a pop up box containing my solution name, but none of the projects are listed.
3) Using File Folder or Nested Namespace still results in the error when the tool is run.
I am using Solution Folders within my solution, but removing them doesn't make a difference.

Hi Mark Dawson,
Can you send us a sample (stripped-out) version of the solution in question? Or a new sample solution that verifies the behavior. We would like to see what is going on as the described behavior should not occur and was never before observed.

Hi,
Sorry I've not been able to get the sample solution to you - I had a deadline to meet which meant I had to just work around the problem by manually adding the generated source files to my solution and then ignoring the Invalid Cast Exception generated by the custom tool - it didn't stop the build of the solution.
I've since upgraded to the Q2 release of OpenAccess and recreated my project from scratch and that has taken care of the errors.
I suspect the problem might have been caused by conflicts between versions. I originally copied the project from another project (lots of common source), stripped out the things I didn't need and then started building up the new project. The old project used the 2009.Q3 version of OpenAccess and I think there might have been something left behind from the old version when I upgraded the project to use the 2010.Q1 version. I'm guessing something gets left in the .csproj file that causes a conflict.
On upgrading this project to 2010.Q2, I started receiving a circular base class reference and will open a support ticket with a copy of the project for you to look at.
Regards,
Mark.

Hello Mark Dawson,
Maybe this was the problem in the first place? Such a circular reference means, the class hierarchy you developed is somewhat wrong from VIsual Designers perspective? I will continue answering that in your support thread.

Hi,
I have the same issue with my testing project. I may provide you the source code if you want.
My solution has two project :
- a library containing OpenAccess schema and generated classes
- a visual studio database project for Sql Server 2008, containing the database structure and stored procedures defintions
When I tried to generate the classes from the OpenAccess schema, I've got the following error :
If the database project is removed from the solution, the entities are generated without error.
For your information, I used Visual Studio 2010 Ultimate Edition. All IDE environment data are provided below :
I am currently testing OpenAccess and without solving this issue, we won't be able to migrate to OpenAccess. So if I can help you, do not hesitate to contact me back. I'll be happy to help.
Kind regards,
Franck

Hello Franck,
Petko_I
the Telerik team
We have observed this issue with the 2010.2.714.1 version of OpenAccess. Is it possible that you are working with this or previous versions of the product? If that is the case, please download our latest internal build (version 2010.2.804.5), upgrade your references and rebuild your project. The problem should be gone as we fixed the issue in question for that build.
Do not hesitate to contact us for any further assistance if necessary.
Sincerely yours,Petko_I
