Svar: Re: A concurrent acces has occurred.

[Morten Schmidt]

Now I updated to the current version (458) Just running this:   IBatisNet.DataMapper.Mapper.Instance();   now gives me a cast error:   Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.   Exception Details: System.InvalidCastException: Specified cast is not valid.   Why is this happening? This is getting frustrating... 5000 updates shouldn't be that big a problem... :o/     /morten     >>>[EMAIL PROTECTED] 05/27/05 8:42 am >>> I-ll be looking into this, and get back to the list with the results... >>>[EMAIL PROTECTED] 05/27/05 4:50 am >>> Wow, great memory Ron!
