I am trying to get these profile "bugs" sorted out for 4.6.0.

I cannot reproduce this on a new install - essentailly 4.5.5 with respect to this error.  In particular I am somewhat baffled by the error.  It states that it is an Object refernce error in the get method of the Format property, which was introduced in 4.5.4 to provide more control over the display of the Date.

Here is the code:

        Protected Overridable ReadOnly Property Format() As String
            Get
                Dim _Format As String = DefaultFormat
                If CustomAttributes IsNot Nothing Then
                    For Each attribute As System.Attribute In CustomAttributes
                        If TypeOf attribute Is FormatAttribute Then
                            Dim formatAtt As FormatAttribute = CType(attribute, FormatAttribute)
                            _Format = formatAtt.Format
                            Exit For
                        End If
                    Next
                End If
                Return _Format
            End Get
        End Property

and

        Protected Overridable ReadOnly Property DefaultFormat() As String
            Get
                Return "d"
            End Get
        End Property

I cannot see under what condition this would throw an null refernce error.

Any ideas?

After some give-n-take with Charles, it's my belief that this issue will be downgraded as "not reproduceable" because Charles has determined the error does not occur in the new v4.6.0 code (or even with a fresh install of V4.5.5). You can see our latest (and probably last) exchange here in the Gemini ticketing system:

If any of you have any further insight into the matter, have at it.  There's no more I can provide to prove there's a real problem.

Hi,

I think it's a versioning thing. I've got a 4.5.5 source install and the Format() routine is missing the IsNot Nothing check on CustomAttributes:

Protected Overridable ReadOnly Property Format() As String
Get
Dim _Format As String = DefaultFormat
For Each attribute As System.Attribute In CustomAttributes
If TypeOf attribute Is FormatAttribute Then
Dim formatAtt As FormatAttribute = CType(attribute, FormatAttribute)
_Format = formatAtt.Format
Exit For
End If
Next
Return _Format
End Get
End Property

Adding the "If CustomAttributes IsNot Nothing Then" (as indicated in Charles') post to the above routine and recompiling fixes the problem.

Hope this helps!
