digitalmars.D.dwt - ColumnView tooltips?

Howdy,
I just tried adding tooltips to a ColumnView following the model of
this snippet:
    http://tinyurl.com/bsjbdz

But I get a crash in HashMap when afterHideTooltip tries to set the
tool tip to "null".

Since this isn't one of the snippets that has been ported, I suspect
chances are about even that this is a problem in DWT itself.
If someone has time on their hands it would be cool to see a port of
that snippet.

Thanks for reporting.

I added this snippet to the dwt-samples repo.

The problem is, tango container crashes on storing a null value for
HashMap!(Object). I added a tango ticket (1468) and a workaround in
dwt-addons.
