I am using version 2013.2.724.40 and I have the following problem. I’m working on an MVVM WPF application. It is a multi-thread application which draws data form a postgres db, displays the data and writes them in to a SQL EXPRESS DB. In one (two) View(s) the data can be displayed and manipulate in a RadGridView this is directly bound to a QueryableEntityCollectionView<>, I’m using the Microsoft Entity Framework.
Occasionally and absolutely not reproducible, but nonetheless too often I get an unhandled EntityCommandExecutionException, mostly when the user push a button to change the View. The Inner Exception is "A severe error occurred on the current command. The results, if any, should be discarded.". If this occurs in the Debugger and when I have a look at the stack, it looks like in the attached picture.
I have the suspicion that comes from the QueryableEntityCollectionView<> bound to the RadGridView, but I have no idea how to prevent this and/or on which place I should enclose some code with a try catch block.
As you can see in the stack none of my functions or classes are involved.
May be someone have an idea.
