We have noticed that certain operations like "Show history view" and "Update to version" at least will fail if the store is not running or reachable. We've left it run for over 15 minutes and it also never timed out. The only remedy left was to kill the process.

OTOH the commit operation works correctly and will request user/password and then fail graciously in a second or two. But I'm no expert in this area of the code to know what would be needed to match the behaviors.

Is this is known issue? Cause it be very problematic when put in novices hand where they just explore menu options.

Thanks
Alain

Hi Alain,

can you post the error message? These features are provided by EMFStore,
but there are no known issues like that.
What do you mean by "We've left it run for over 15 minutes"? Do thoses
errors occur while EMFStore is running or not? Are you running a local
store within the demo application?


Best Regards

Jonas

There are no error messages, the UI simply gets frozen.

Just what it says, left the dialog try to connect to the server with the application frozen.

>>Do thoses errors occur while EMFStore is running or not?
This is the whole point I'm making, it happens if the store related to the project is not running or unreachable. What is wrong is that the application should notice that the connection can't be made and simply provide a message to the user. As I stated, the commit operation works like that right now and it is views like history view and update to version that are misbehaving.

>>Are you running a local store within the demo application?
Both, the issue is the same.
