The problem is that the grid sets the value of the "id" attribute of each
row to an integer (rather than the string representation of the integer),
but the .element method ends up comparing the integer to its string
representation. For further details, see the issue
<https://github.com/web2py/web2py/issues/1074> I just submitted.
For now, there is a workaround -- instead of passing in a string or integer
as the argument to .element(), you can pass in a compiled regular
expression, which will get compared to the string representation of the _id
instead of the original integer value:
import re
print grid.element(_id=re.compile('2'))
