Hi!
I activate servermode for my WebApp.
Now, if I click on edit for inline editing and then press cancle I get the following error:
The masterObject belongs to a different ObjectSpace Parametername: masterObject
If I click save, it works just fine.
Steps to Reproduce:
See the video
Actual Results:
Cannot access a disposed object.
Object name: 'DevExpress.Xpo.UnitOfWork(64)'.

Hello Robert,
Thanks for reporting the issue.
In order to fix the issue, we must first reproduce the issue in our labs. We are unable to reproduce the issue with the steps you provided. It all works fine for us in our tests. Could you please provide us with the following info?
Thanks,
Dennis
Hi Dennis, the problem is, I can't reproduce it in the DemoProject.
It look like, that it has nothing to do with Servermode but how can I check if the
application realy uses the Servermode ?
The crazy thing is, that I get no error in the VisualStudio Outputwindow (Trace) wenn I click cancle.
If I then click a second time on cancle or switch to an other navigationitem, the error appears in the output.
I have deactivated all my ViewControllers but the error is still there.
hope you can help me finding out where this error come from
Hello Robert,
Thanks for the video you sent to us. Unfortunately, it did not help us much. We cannot determine what's wrong with your project just looking at the problem and not being able to play with it. The call stack you captured doesn't help us find the cause of the problem. We need a sample.
Could you please send us a copy of your real project? Before that, please remove unnecessary parts of the code, which don't relate to the current problem. Please leave only the classes involved in the scenario, in which this error is reproducible. If it is not possible to prepare such a test project, we are ready to investigate your entire project. In this case, please give us a simple step-by-step instruction on how to make it run in a regular environment, so that we can easily investigate it ourselves.
To safe your property here, I have marked this issue as Private.

<<
If you set the UseServerMode options your application should work in this mode. In this mode the ServerCollectionSource class is used in list views.
Thank you for your effort,
Dennis
Hi Dennis, I tried my best to simplify the application.
You need a sample database (MSSQL) named B133946.
In den Updater.cs I insert the minimum sample data.
You can login with the user Admin and no password.
Then click the edit link for inline editing and then click cancel like I do it in the sample movie.
thanks
robert
Hello Robert,
Thanks a lot for your sample. We have had no problems in forcing it to run. I can reproduce the problem using the latest version of XAF.
I briefly checked your Task class and it seems to be correct, though it requires a more closer look.
I also noticed that this problem is reproduced in all InlineEditModes for this class, but everything works fine for other classes. The problem looks like a bug caused by incorrect code in the Task class or a Controller for this class. To ensure this, we will investigate your solution more deeply, and will let you know about our results soon.
Thank you for your patience,
Dennis
