In the BeforeSave event on my BO I am adding records to a secondary table using another BO.  This secondary BO is adding the records correctly,  but it appears that the BeforeSave event on the primary BO is fireing twice.  Any suggestion on what I should be checking.

Within your InitializeComponent() method, of the business object, you should find a line similar to:



this.BeforeSave += new BeforeSaveEventHandler(SFCategoryBO_BeforeSave);



Make sure you don't have two of those lines.



Also, are you doing anything special like using the business object on a child form that's shown through a ChildFormDialog, or within a UserControl?



I've checked, and there's no place that the event is being raised twice, but it's possible that the event handler is being added twice...

Did not find any duplicate handlers.  Try this,  I went to the Strataframe sample windows application and added a beforesave event by double clicking on the event in the property sheet.  I then put the following code in the event:

System.Console.WriteLine("Before Save Event")

run the form, locate a record, click the edit button, (do nothing) click the save button, and look in the console, there is two "Before Save Event" messages. Is this the expected result?  I hope I just am not miss-understanding how the event is supposed to work.

OK, found the problem... there was an event that was being raised from within the DataLayer, not the BusinessLayer, and it was getting bubbled up and re-raised from within the BusinessLayer. I'll get the update posted on the Developers blog shortly (running all of my unit tests right now) and then we'll get the install rebuilt.



So, no, your concept of the BeforeSave event is the same as our concept of the BeforeSave event... it should only be firing once.

Great.  Nice to know I am not going crazy and starting to understand how the framework works.  How would you debug something like an event anyway?  I wouldn't even know the first place to start.

Hehe, events are special... it's quite difficult to debug them. Within the framework, where we call RaiseEvent, you can step into the line and you will step into all of the methods attached to that event.



BTW, the update is posted on the Developers Blog.

Thanks for the update.  Works great.

No problem, we'll get the install rebuilt and posted as soon as we can
