Tooltip Problem in Navigator

[dlayne]

Found a tooltip bug. When the navigator is in HeaderBarCheckButtonHeaderGroup mode, and you hover over the Close or Context buttonspec (the default internal buttonspecs) you will get a null object exception, every time.

To make sure it wasn't me, I debugged this in the 2.6.0 source and found the error occurs at ViewBuilderItemBase.cs, line 225:

Code: Select all

        public override ButtonSpec ButtonSpecFromView(ViewBase element)
        {
            return _buttonManager.ButtonSpecFromView(element);
        }


because _buttonManager is null. Didn't check other modes except to note that the default doesn't experience this.

Thanks for this, I will update the code base straight away.
