Setting LastError on page in business logic
03/01/10 at 22:16:48

I have an issue with error reporting ... dont know how to work around

SubmitLast doesn't show error popup

My code is as follows (formContainer is always the page):
Code:


if (formContainer.LastError.Text == "" && formContainer.LastError.Code == 0)
{
	if (connection.LastError.Text == "")
        {
		formContainer.LastError.Code = 0;
		formContainer.LastError.From = ErrorSource.Application;
                formContainer.LastError.Text = ex.Message;
	}
        else
        {
        	formContainer.LastError = connection.LastError;
	}
}

I have tried just throwing an exception instead of the above code - but that doesn't work either.

Any ideas? What could be happening?

Hi Mark,

The answer is that the LastError property needs to be set to a new Error instance, rather than each individual property being set separately. Please see below for two examples of how it should work:

Visual Basic code sample
Code:

' #18126 - Setting LastError on top level container in business logic 
Public Sub pgTest_Create(page As ndxContainer)
    Dim error As New ndxError
    error.Code = 123
    error.Text = "Test error"
    error.From = ndErrorMail
    page.LastError = error 
End Sub

C# code sample
Code:

// #18126 - Setting LastError on parent container in business logic
protected override void OnSubmitLast(Container container)
{
      base.OnSubmitLast(container);
      Error error = new Error();
      error.Code = 456;
      error.From = ErrorSource.Application;
      error.Text = "Test Error";
      container.Parent.LastError = error;
}

I hope this helps.

Cheers,
Mike.
