XML Deserializer problem

Guys,

Have very strange issue with deserialization. Really need help,
because i just don't getting why the hell this not works in a way it
suppose to be.

Here is the sample object i serialize into XML:

<XmlRoot("CONTACTS")> _
    Public Class Contacts
        <XmlAttribute("version")> Public Version As String = "0.2"

        <XmlElement(Type:=GetType(OrganizationType),
ElementName:="ORGANIZATION", IsNullable:=False,
Form:=XmlSchemaForm.Qualified), _
                 EditorBrowsable(EditorBrowsableState.Advanced)> _
                 Public __Organizations As OrganizationColectionType

        <XmlIgnore()> _
        Public Property Organizations() As OrganizationColectionType
            Get
                If __Organizations Is Nothing Then __Organizations =
New OrganizationColectionType()
                Organizations = __Organizations
            End Get
            Set(ByVal Value As OrganizationColectionType)
                __Organizations = Value
            End Set
        End Property
    End Class

Deseriliazing i do via this function:

    Public Function SetXml(ByVal obj As Object, ByVal XmlData As
String) As Object
        Dim ser As New XmlSerializer(obj.GetType)
        Dim ms As New
IO.MemoryStream(Text.Encoding.UTF8.GetBytes(XmlData))
        Dim xr As New Xml.XmlTextReader(ms)
        Debug.WriteLine("Can deserialize: " +
ser.CanDeserialize(xr).ToString)
        Return ser.Deserialize(xr)
    End Function

On ser.CanDeserialize it always return /TRUE/ that i assume tells that
source XML is fine. At least it says "Gets a value that indicates
whether this XmlSerializer can deserialize a specified XML document."
on http://msdn2.microsoft.com/en-us/library/system.xml.serialization.xmlserializer.candeserialize(VS.80).aspx

But problem is that actual deserialization is never happens. Object
not getting filled with data from XML.

If i take any other object to deserialize, i get my data, but objects
build like this are failed.

Is anyone have any idea wtf is wrong?

Cheers,
Evi.

Yes, it looks very fine. The actual serialization output is this:

<CONTACTS xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" version="0.2">
<ORGANIZATION name="Org1" shortName="org1">
<PERSON firstName="John" lastName="Doe"
emailAddress="j***@local.vpn" />
</ORGANIZATION>
<ORGANIZATION name="Org2" shortName="org2" />
</CONTACTS>

What does your call to SetXml() look like? I'm guessing it looks like this,
but I don't want to assume that it does:

Contact2 = SetXml(Contact1, theXmlString) ' note, contact1 is not changed
in this call, only used to get the data type.
