Click here for a list of known issues with this version. Release 4.0.0-100723: LoadProperty (100722) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=772 Apply the non-generic LoadProperty() change to CommandBase and ReadOnlyBase. RC1 4.0.0-100719: Samples (100719) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=748 Removed all samples that won¡¯t be updated for CSLA 4 to avoid confusion. Some of these samples may come back in the future as time permits, but for now only samples that build in CSLA 4 will remain. RuleUri (100719) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=802 Add Arguments property. EditableRootListBase (100719) Breaking change http://www.lhotka.net/cslabugs/edit_bug.aspx?id=769 Renamed ERLB to DynamicListBase and DynamicBindingListBase. Fix base class types for WPF/SL as well as Windows Forms. Fix AddNewCore() on .NET side so it returns type T instead of object. Snippets/Templates (100716) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=799 http://www.lhotka.net/cslabugs/edit_bug.aspx?id=798 Add and update some snippets and templates for VB and C#. LoadProperty (100715) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=772 Undo the Beta 3 change to the non-generic LoadProperty() method so the non-generic LoadProperty() no longer calls the property setter. Calling the property setter is problematic, because it forces properties to have setters, and forces Silverlight setters to be public. The new implementation of the non-generic LoadProperty() now uses reflection to directly invoke the generic LoadProperty() method. This ensures that the non-generic behavior is the same as the generic behavior, and doesn¡¯t require that properties have a setter. Child data portal (100715) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=738 Fix null reference issue in the exception handling code in child data portal. Dependency rule (100714) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=801 Constructor for Dependency rule now accepts a list of affected properties, allowing for one-to-many dependencies to be established with a single rule. BusinessRules (100719) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=796 If a rule throws an exception, BusinessRules now includes the rule:// URI as part of the description (along with the exception Message property) to make it easier to determine which rule threw the exception. RC0 4.0.0-100708: Snippets/templates (100708) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=795 Update snippets and templates for CSLA 4 changes. Data portal exceptions (100708) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=794 Fix bug with data portal exception handling and SilverlightRequestProcessor. CslaModelBinder (100708) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=790 Add support for block mode updates and make that the default. CslaModelBinder now suppresses rule checking, allows the model properties to be updated, then runs all object rules before saving the object. This involved adding an ICheckRules interface to CSLA, so other UI frameworks can also use this interface to suppress/resume/check rules. Business rules (100707) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=793 Add Dependency rule to enable reverse dependent properties. BusinessPrincipalBase/CslaPrincipal (100707) Breaking change http://www.lhotka.net/cslabugs/edit_bug.aspx?id=787 Rename BusinessPrincipalBase to CslaPrincipal. BusinessBase (100705) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=788 Remove non-async DataPortal_Create() method from Silverlight implementation. BusinessRules (100705) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=792 Fix bug in GetFirstMessage(). BusinessListBase (100704) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=25 Throw an exception when a non-child object is added to a BusinessListBase. PropertyStatus (100629) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=785 Fix issue with PropertyStatus not displaying/refreshing properly. ObjectStatus (100629) Breaking change http://www.lhotka.net/cslabugs/edit_bug.aspx?id=786 Remove ObjectStatus. RuleUri (100625) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=784 Encode path data to handle special characters. Beta 3 4.0.0-100625: CslaDataProvider (100625) Breaking change http://www.lhotka.net/cslabugs/edit_bug.aspx?id=783 The RemoveItem() method now accepts two parameters (sender, ExecuteEventArgs) so it is compatible with TriggerAction and InvokeMethod. RuleUri (100625) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=782 Fix an issue where a long type name would cause System.Uri to fail. On .NET it has a limit of around 256 characters, and on Silverlight just 63 characters for each part of a path name. The fix breaks any long type name into 63 character parts behind the scenes, allowing System.Uri to work as expected. LoadProperty (100624) Breaking change http://www.lhotka.net/cslabugs/edit_bug.aspx?id=772 The non-generic LoadProperty() method now always invokes the property setter, so it indirectly always uses the generic LoadProperty() method. This means there is complete parity between the two implementations, but it does mean there¡¯s slightly more overhead with the non-generic version of the method. In the case of BusinessBase, the property setter is invoked within a BypassPropertyChecks block, so it does a load operation, not a set operation. IsBusy/IsSelfBusy/IsPropertyBusy (100624) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=780 These three property/methods are now virtual. Async rules (100623) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=779 Provide the Target property to an async rule if the rule explicitly sets a ProvideTargetWhenAsync property to true. Obviously if the rule uses the Target property on a background thread that¡¯ll cause major problems, but that is just bad code and the developer deserves what they get. This does have some interesting ramifications for rule chaining. If async rules chain to other rules (sync or async), the Target value is only provided through the chain when the parent async rules (all the way up the chain) have ProvideTargetWhenAsync set to true. ASP.NET MVC Authorization (100623) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=778 Added HasPermissionAttribute and a set of HasPermission Html extension methods to simplify applying CSLA per-type authorization rules to controller actions and code in a view. ASP.NET MVC ViewModelBase (100623) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=766 Added a ViewModelBase class to provide a basic implementation of IViewModel. BusinessRule (100623) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=777 Remove unused default properties from the base class. RuleContext (100623) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=776 Add a public constructor to enable simpler unit testing of rules. Authorization (100616) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=773 CanReadProperty/CanWriteProperty now call FirstOrDefault. File headers (100614) http://www.lhotka.net/cslabugs/edit_bug.aspx?id=717 All code files now contain a standard co
