[antlr-interest] Problem with integrating ANTLR with XAML

[Glenn Rowe (Orders)]

Hi Sam:

I don't try to reference FormulaLexer or FormulaParser in the XAML file, but
I need some
of the other classes in the FormulaPlotter namespace in the XAML. I've tried
putting
the ANTLR stuff in a different namespace from the MainWindow stuff, but it
doesn't help.
I've also tried putting the C# code that references the ANTLR stuff in a
separate namespace
from MainWindow but that didn't help either.

Basically, the program has a DataGrid which is data-bound to a DataTable, in
which I
store the strings representing the formulas to be plotted and the colour of
the
plot line and so on. The user enters the formula and colour in the DataGrid
in the GUI and
these are connected to the DataTable via data binding.
So I'd like to be able to refer to the DataTable in the XAML in order
to bind some of the display properties to entries in the DataTable.

The errors cause the build to fail. I know that sometimes ANTLR will show
errors in the
errors window which go away when you do a build, but these errors are 'real'
errors
that cause a build fail.
