I have a custom dialog view, but when there are no spelling errors, the following exeption occurs:

System.NullReferenceException occurred
Message=Object reference not set to an instance of an object.
Source=Keyoti4.RapidSpell.WPF
StackTrace:
at Keyoti.RapidSpell.Wpf.RapidSpellGUIPresenter.p()
InnerException:

Any ideas why this might be happening?

Hi, I need more info please - the full stack trace may help, but also understanding what you're doing. The code for the custom dialog would be helpful The best would be a simple mockup that uses your custom dialog, so I can see it happening.

If you want to send anything you could use http://mediafire.com

Thanks
Jim

I cannot make a mockup, the only thing I have is a stacktrace for you.

I can only guess, without a mockup - looks like maybe the DialogView property in the RapidSpellGUIPresenter is null when the exception occurs. Sounds related to your custom view. Can you look at RapidSpellDialog.UserInterfaceFormPresenter.DialogView and see if I'm right?

More info is useful.

I just updated to v3.0 and the exception seems to be gone. When I encounter it again, I will keep you posted.
