Not initialized in user control?

Any ideas as to why AR isn\'t being properly initialized when being used inside a user control? My initialization is properly being executed AFAIK because my parent form is successfully able to query.

Any ideas as to why AR isn't being properly initialized when being used inside a user control? My initialization is properly being executed AFAIK because my parent form is successfully able to query. However, when I try querying within my u开发者_运维技巧ser controls I get Warning 1 An ActiveRecord class (Binder) was used but the framework seems not properly initialized. Did you forget about ActiveRecordStarter.Initialize() ? 0 0. Which stops me from dragging my user control onto the form. If it helps, I initialize AR in Program.Main().

Here is the stacktrace:

at Castle.ActiveRecord.ActiveRecordBase.EnsureInitialized(Type type)
at Castle.ActiveRecord.ActiveRecordBase.FindAll(Type targetType, DetachedCriteria detachedCriteria, Order[] orders)
at Castle.ActiveRecord.ActiveRecordBase.FindAll(Type targetType)
at Castle.ActiveRecord.ActiveRecordBase`1.FindAll()
at TxLocates.BinderTabReferenceControl.BinderTabReferenceControl_Load(Object sender, EventArgs e) in C:\dev\TxLocates\src\TxLocates\BinderTabReferenceControl.cs:line 56
at System.Windows.Forms.UserControl.OnLoad(EventArgs e)
at System.Windows.Forms.UserControl.OnCreateControl()
at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)
at System.Windows.Forms.Control.CreateControl()
at System.Windows.Forms.Control.ControlCollection.Add(Control value)
at System.Windows.Forms.Form.ControlCollection.Add(Control value)
at System.Windows.Forms.Design.ControlDesigner.DesignerControlCollection.Add(Control c)  


The Visual Studio designer executes OnLoad for your user control, but doesn't run Program.Main(). Therefore ActiveRecord isn't initialized in the context of the designer.

Workarounds: use the DesignMode property to detect design mode to avoid executing ActiveRecord-related code, or try calling ActiveRecord from a different event.
