VS Shell / Package: GoTo Line is not working in custom editor.

Hello,

I am creating a new custom WPF Editor in VS2010 and I noticed that the GoTo line / menu's is not working. When my editor first opens then the menu is enabled but the line count in the menu shows that i can go to line 1 (only 1 line in the document), but as soon as I click cancel all of the goto menu's and keyboard shortcuts are disabled. I set a breakpoint on any code that returns a line count and it still has this same behavior. I really don't want to implement this using a custom goto dialog and this code:

addCommand(mcs, VSConstants.GUID_VSStandardCommandSet97, (int) VSConstants.VSStd97CmdID.Goto, OnGoto, OnQueryGoto);

Has anyone else run into this behavior?

    [ComSourceInterfaces(typeof (IVsTextViewEvents))]    [ComVisible(true)]    public abstract class EditorPaneBase :        WindowPane,        IPersistFileFormat, //to Enable persistence functionality for document data.        IVsPersistDocData2, //to Enable persistence functionality for document data.        IVsFileChangeEvents, //to notify the client when file changes on disk        IVsDocDataFileChangeControl, //to Determine whether changes to files made outside of the editor should be ignored        IVsFileBackup, //to support backup of files. Visual Studio File Recovery backs up all objects in the Running Document Table that support IVsFileBackup and have unsaved changes.        IVsStatusbarUser, //support updating the status bar        IVsFindTarget, //to implement find and replace capabilities within the editor        IVsTextImage, //to support find and replace in a text image        IVsTextSpanSet, //needed for Find and Replace to work appropriately        IVsTextView, //Manages the text view of an editor window. Contains methods to manage the text view. The view is essentially the editor window shown in the UI.        IVsCodeWindow, //needed for Find and Replace to work appropriately        IVsTextLines, //needed for Find and Replace to work appropriately        IVsToolboxUser, //Sends notification about Toolbox items to the owner of these items        IExtensibleObject,  //so we can get the atuomation object        Document

I've checked the following methods and this doesn't alter this behavior:

        /// <summary>        /// To return the number of lines in the text image        /// </summary>        /// <param name="pcLines">pointer to the number of lines in the text image</param>        /// <returns>S_OK</returns>        int IVsTextImage.GetLineSize(out int pcLines)        {            //get the number of the lines in the control            pcLines = GetTotalLineCount();            return VSConstants.S_OK;        }

public int GetLineCount(out int piLineCount)        {            piLineCount = GetTotalLineCount();            return VSConstants.S_OK;        }

Thanks
