CSLA 2.1 Validation Problem

JZuerlein posted on Monday, August 21, 2006

I'm doing some testing with 2.1 and started coming across some problem when I try to add validation to a class. The ValidationRulesManager is not nothing, but the children can not be evaluated. So when you try to get the list of rules for the property, a null reference exception is thrown. Has anyone seen this before?

ValidationRules.AddRule(AddressOf CommonRules.StringRequired, "Name")

End Sub

I appreciate you taking the time to test 2.1!

That sounds somewhat familiar, and is probably resolved in the current code. There were a couple places where I wasn't doing null reference checks quite right - hopefully I've caught them all.

Look for a refresh of the beta code yet this week - both VB and C# this time.

So you are saying that AddBusinessRules() isn't being called? There is code in BusinessBase that makes this call - but in the current code it only happens once per appdomain, because these are the per-type rules. In other words, only the first object of a given type gets this call - all subsequent objects of that type do NOT get the call because the per-type rules have already been loaded.

Any way I could get an current build? A coworker and I are writing the validation code and unit tests this week for a project that's due at the end of Sept. We need the severity features to make it work, so rather then roll our own...

Sure, you can use TortoiseCVS to get the current code through anonymous cvs at any time.

Just make sure to use the revision tab to get branch V2-1.
