IndexOutOfRangeException

mase posted on Friday, September 26, 2008

I'm using CSLA 2.1 and have been having these error intermittently since the launch of the web application. I'm not able to reproduce it or track it down and need help!
I posted about it here a while back: http://forums.lhotka.net/forums/post/23987.aspx

I have a pretty standard and basic Business Object library. I do not utilize Authorization Rules and sometimes add Validation Rules.  It doesn't appear to be consistent either. It happens on any/all business objects and always seems to stem from the CanReadProperty()

Index was outside the bounds of the array.

Exception type 'System.IndexOutOfRangeException' was caught.

==============================================================

Since you are not using Authorization rules, just remove the CanReadProperty code from your Properties. Then see if the problem goes away.

I will give that a shot and see if it works.

I had the CanReadProperty() and CanWriteProperty() because I imagined introducing Authorization rules eventually.

Can you refresh my memory as to what Authorization rules would be used for? What is the situation and benefit for using them?  Is it essentially for permissions and roles on the business level?

mase replied on Friday, September 26, 2008

Also, I can't figure out why it happens sometimes but not consistently. Why would having this code (CanReadProperty(true)) work ok 90% of the time and then produce an exception the rest of the time? Espeically if I have not setup Authorization rules, I would expect it should behave the same way each time.

Thanks for the help

Don't use the overloads of CanXXXProperty that don't take the property name.  They have been depreciated in future versions, and have been the source of many problems.  You may be hitting the debug vs. release compilation issues.

mase replied on Monday, September 29, 2008

Ok, great. This is exactly what I have been wondering about. Good to know. Removing them and hopefully will see these errors disappear.

ajj3085 replied on Monday, September 29, 2008

Well, if you want to use auth rules you should still call CanXXXProperty... just don't call the ones that omit the propertyName parameter.
