DSW with ORM 2010 Q1. Object reference not set.

[Lee]

I'm able to step through the samples on creating a class library, then a blank web project.  Then start the Data Services Wizard and get all items as expected through to Finish.  As soon as I click finish I get Object reference not sent to an instance of an object, regardless of what type of service I select.

I've re-installed DSW multiple times.  I am using Windows 7 x64 on Visual Studio 2008 sp1.
Is there incompatibilty that I am not aware of?

[Peter Bahaa]

Hello Lee Weisenberger,

The cause for this issue is that the Telerik.OpenAccess.Query.dll is now renamed to Telerik.OpenAccess.35.Extensions.dll in the latest version of OpenAccess but the DSW still references the old assembly. We are planning to release a new version of the Data Services Wizard next week with some new exciting Silverlight features. Sorry for the inconvenience.

Hello

(Sadly), I am pleased that someone else is experiencing this issue.

I have been trying to get this to work for a good few days, and thought that it must be something I was doing wrong.

I  have started many applications from scratch, reinstalled Open Access and DSW many times, read ALL the documentation but still no cigar.

Will I be notified when the new wizard is put into my user area, or do I just keep checking ?

Best regards
Bill

Hi Bill Noble,

I will notify you in this thread once this issue gets solved. You can expect the new version by the end of the next week.

I installed the new version, but I still get the same error "Object reference not sent to an instance of an object" in the last step of the process.

[Peter Bahaa]

Hi Juan Valenzuela,

We have done numerous tests here locally and we could not reproduce the issue you have reported. Can you please confirm that the wizard was properly uninstalled before the installation of the new version? Maybe an old assembly was not uninstalled for some reason? Please try to uninstall the wizard and install the new version again after you have made sure that there aren't any old assemblies left. Do come back to us if this does not fix your problem.

Best wishes,

I uninstalled and re-installed. Same error.

Is anybody else in this thread having the same problem or am I the only one?

Thanks

I was having the "Object reference not set" problem before the update..., but I uninstall --> install update, and now is working ok.

Hi There,

I'm afraid that I'm still getting this error in some circumstances. Everything works ok if I right click a .rlinq file and launch the wizard from there but, when I launch the wizard from the top Telerik menu and select a class library which uses forward mapping I get the "object reference not set..." error when I click next from the Discoverer Chooser step. I've tried this on both my main application and a brand new test one which contains nothing but a scope provider and a single forward mapped class, both give the same error.

Any ideas?

Matt

[Peter Bahaa]

Hello,

@Matt.F: Please try uninstalling the wizard, and reinstalling it again.

@Juan: We already scheduled this issue to be fixed in the next build. For more information on the new features in DSW please see the documentation zipped with the release.

[Matt.F]

Hi There,

Tried this several times, also tried uninstalling wizard, removing orm, rebooting pc and then reinstalling piece by piece after validating no wizard componants remained. Still only works for the .rlinq files not the forward mapping.

Is there any way that I can get more information on this error to give to you?

Also, I noticed that the date of the setup.exe / msi in the file Telerik.OpenAccess.DSW.zip currently available for download on telerik.com is 31/03/2010, is this correct? From reading through the posts in the thread I would have expected it to be dated April rather than March.

Thanks

Matt

[Matt.F]

Hi again,

Sorry to be a pain but is there any further help you can give on this issue? I'm trying to persuade the people who hold the purse strings to fork out for a few licences for your software but at the moment I cant really as the openaccess / data services wizard was a bit of a deal breaker.

Thanks

Matt

[Bill Noble]

Hi Juan
I was having the exact same issue.
I downloaded the zip file numerous times, uninstalled the old one and reinstalled the “New” one, only to get the same error each time.

I read the documentation and forum posts etc.
I thought that I would give it one last attempt before jumping off the local bridge J.

I had noticed that there were various links on the site, pointing to the ‘same’ zip file, and in desperation, I clicked on a link that I had not previously used, and downloaded the file.

I went through the usual uninstall, reinstall phase, but using this new zip file, and my issue disappeared.

I wonder if there had been some old version lurking somewhere.

Bill

[Jim]

Thank you Bill. You wouldn't happen to remember which link was the one that did it for you, would you?

I'm downloading the "official" released one from http://www.telerik.com/documents/Telerik.OpenAccess.DSW.zip

Regards

- Juan

[Bill Noble]

Hi Juan

 Sorry, I can’t remember the exact link, although they should all be the “same” file.

Go to control panel – programs and features and check the version,  10.03.3109 is the one I have.

I uninstalled the old version via windows control panel.
Re-started the computer.
Unzipped the DSW.zip into a new folder.
Ran the setup as administrator.
Started VS2008 and created a new project.

Bill

[Jim]

Thanks Bill,

I was finally able to make it work. I was having issues with all Telerik products. I uninstalled ALL of them. This was not enough. I noticed that after uninstalling, there are still many entries on the registry. I used a program called RegScanner and searched all keys and values with the word 'Telerik' on them and deleted them.

Rebooted and re-installed and that made it work.

- Juan

[Bill Noble]

Hi Juan

I’m pleased you got it working, and thanks for the tip about RegScanner.

Hi Byron Blattel,

Can you please provide us with some additional information in order to reproduce the false behavior you are observing. We tried to run the wizard on a clean installation and everything worked as expected. Can you please confirm that prior to installation you did not have any old assemblies left from previous installations?

All the best,
Petar

I ran the uninstaller from 'Programs and Features' before installing 2010.1.527.1.  I just searched my system and didn't find any older OA .dlls...

[PetarP]

Hello Byron Blattel,

The place where you need to search is located in the assembly folder in your Windows folder installation. Usually this is C:\Windows\assembly. There you will have to search for everything Telerik.OpenAccess.* related. If you can indeed confirm that there aren't any old assemblies please install the latest version and try to use the wizard again. If you are still experiencing problems can you please provide us with additional information on how to reproduce the false behavior as everything works as expected on our side.

Best wishes,

I've completely uninstalled all Telerik products and reinstalled the latest builds of OA and RadControls for SL.

After the uninstall there were no Telerik dll's listed in C:\Windows\assembly...

I still get the error.

I've attached screenshots of the debug output and loaded modules.

If I had the .pdb for  Telerik.OpenAccess.DSW.Providers.dll I could give you more info...

[PetarP]

Hi Byron Blattel,

can you please be more specific on the steps you performed that caused the exception? What project did you have in your solution? Did you used Northwind, AdvantureWorks or a private database? Any information on how to reproduce the problem will be greatly appreciated.

Kind regards,
Petar

[DSamani]

I have figured out the problem. The exception is thrown if the web project's web.config file does not have a <connectionStrings> element yet.

If you manually create a <connectionStrings> section the exception is not thrown.  FYI the offencing code is in Telerik.OpenAccess.DSW.Presenter.Presenters.FinishPresenter.SaveProject() when base2.ModifyConfigFile(...) is called.

Hi Byron Blattel,

Thank you for helping us to find the source of the problem. This issue is already fixed in our latest internal build.

Rizk,

Note that it's not fixed in 2010.1.610.1, which appears to be the latest internal build available to customers.  I think you're referring to an internal build that we cannot get yet.  That's not a problem, since we have the workaround, but I thought a clarification would be useful.

Hello James,

Actually I was referring to an internal build which is not public yet, sorry for not clarifying that. You can expect this build in a couple of days.

Hi,
I ran in the same issue after installing ORM 2010 Q1 (0527). I use VS 2010 and have a class modell project and a winform project. My app.config have a <connectionStrings>-section.

Here same information from the output:

Calling: "c:\program files (x86)\telerik\openaccess orm\sdk\VEnhance.exe" -assembly:"C:\Projekte\PADUA\Kerndaten\obj\Debug\ZentraleDaten.dll" -config:"C:\Projekte\PADUA\Kerndaten\App.config" -verboseMode:1

I need a workaround, because our team project stands still.

Hi,
thanks. It's fine now.

[Niall]

Hi,

I'm trying to generate the code to reflect changes we've made to our database.
The product is quite mature and we've been making changes recently which we've struggled to refliect via Telerik Open Access ORM because it is unbelievably unreliable and processor intensive, but until now I have been able to eventually generate the code to reflect the changes.

I've just made some very minor changes to the data model adding a new FK to a table but the DSW now gives the "Object reference not set to an instance of an object" error when I click "save and generate".

I've uninstalled and re-installed and restarted several, times now, but the problem persists.
My colleague has tried to generate the code as well, but he gets the same error so the problem seems to be with Telerik.

Versions are 2010.1.312

Thanks, Niall...

[Serge]

Hello Niall,

 Unfortunately I am unable to reproduce the exception that you are experiencing. Is switching to a newer version of OpenAccess and making use of the new Add OpenAccess Service wizard an option? If you insinst on using the version you have though, is it possible that we get the model containing your project or just the rlinq so that we can test it locally. It is quite possible the issue is only reproducable with certain kinds of mappings. 

I am looking forward to resolving this issue. 

Kind regards,
Serge
