I see that the invalid _compileExpression was fixed but this was a 2 fold
defect. I think you overlooked my comment about on demand CompiledExpression &
problem with expressions that depends on columns that are defined after the one
with the expression. So DataTable.Clone fails when column 1 has an expression
depending on column 2. This is because the cloned column 1 expression is
compiled before the cloned column 2 is created.
Should I reopen the defect or create a new one?
