Hm, that's a bug. I probably never noticed because I don't instantiate my
columns
that way.

Probably a bug, too. I'd need to think about it.

It should persist no matter how the column was instantiated.

That's expected.

It should be permitted. For what it's worth, here's how I tend to instantiate
grids
and columns:
{{{
from dabo.ui import dGrid, dColumn
class Column(dColumn):
def initProperties(self):
self.HeaderFontBold = True
## other common properties set here
class Grid(dGrid):
def initProperties(self):
self.DataSource = "customers"
def afterInit(self):
self.addColumn(Column(self, DataField='name', Caption='Name'))
self.addColumn(Column(self, DataField='phone', Caption='Phone'))
}}}

I guess we need a different bug report for that.
Please file these reports on our github issue tracker.
And thanks again for testing different cases and following through. I'll try to
reciprocate.
