I still seem to be getting an error using the .NET client API to access Version Attributes.

The REST exception I used to get is now gone, but

attributes = sm.ProjectsService.GetProjectVersionAttributes(version.ProjectID)

fails when I later try to reference attributes, saying "Object reference not set to an instance of an object".. I know that the project ID is correct, as it's being retrieved from a VersionEN object which correctly returns a VersionNumber when asked to.

I'll post the full code, but this isn't my development machine, so I'll need to go do some copying.

Any ideas?

EDIT:

Complete code:

versions = m_smProxyManager.ProjectsService.GetVersions((int)selectedProject.ProjectID);

versionHash = new Hashtable();

lstVersions.Items.Clear();

for (int i = 0; i < versions.Length; i++)

{

    VersionEN version = versions[ i ];

    if (!version.VersionReleased)

    {

        String versionName = version.VersionName;

        this.versionsByName.Add(versionName);

        versionHash.Add(versionName, version);

        lstVersions.Items.Add(versionName);

    }

}

...

selectedVersion = (VersionEN)versionHash[lstVersions.SelectedItem];

...

FormReleaseNotes frn = new FormReleaseNotes(m_smProxyManager,notes,selectedVersion);

DiagnosticsManager.TraceMessage("Release notes opened with version " + selectedVersion.VersionNumber + " and notes " + notes);

frn.Show();

...

public FormReleaseNotes(CounterSoft.Gemini.WebServices.ServiceManager sm, String initialText,VersionEN version)

    InitializeComponent();

    m_smProxyManager = sm;

    releaseNotes = initialText;

    this.textBox1.Text = releaseNotes;

    this.version = version;

    attributes = m_smProxyManager.ProjectsService.GetProjectVersionAttributes(version.ProjectID);

    foreach (ProjectVersionAttributeEN att2 in attributes)

    ...
