Hi all,
I've bought the book (C# version at bookpool.com) and was impressed as soon as i got reading it. Great work. When i downloaded the code from this site i was trying to play a bit with it but got stuck with the following.
The following exceptions (see lowest part of this post) i get when i run the sample windowsforms tracker.
What i do is login as "power" and then open the projects for edit.
project "Expert C# Business Objects"
Select one resource. "Jefferson Thomas"
change the lastname to "Jefferson TEST" press the apply button and then the exception are raised over and over again when you move the mouse over the grid.
What i'm doing wrong ? Or is it a bug ?
I think i found the problem maker in ResourceEdit.cs I've added 1 line of code. And marked it green
private void SaveResource(bool rebind){
using (StatusBusy busy = new StatusBusy("Saving...")){
// stop the flow of events this.ResourceBindingSource.RaiseListChangedEvents = false; this.AssignmentsBindingSource.RaiseListChangedEvents = false; // do the save Resource temp = Resource.Clone();temp.ApplyEdit();
try{
_resource = temp.Save();
_resource.BeginEdit();
if (rebind){
// rebind the UI this.ResourceBindingSource.DataSource = null;ApplyAuthorizationRules();
}
}
Greetings Andre Mens

Hi Rocky
You're correct in this. Only the erata you're talking about is already fixed in the version i have the problem i've stumbled on is in a different file ResourceEdit.cs
It looks like the samen coding bug.
Greetings Andre
Got it - thanks! I have fixed this now in cvs and it will be part of 2.0.1.
