The row howto has a syntax error in the bit about rowForeignKeys. "[(tableName, [(columnName, columnType)], containerMethodName, autoLoad]" I had a look at the source code, and the error appears to be a little deeper, in that there should be two lists of columns, one for parent columns, one for child columns.
