[GoogleCodeExporter]

What steps will reproduce the problem?
1.i use doctrine 1 as source for my grid 
2.in the from crud i can't update a column to null , i have a column with int 
type , and when i want to update this column value to null i have error message 
that null is not a valide integer 
I tried
new doctrine_null() , NULL, PDO_PARAM::NULL 
for each tries a have the same error

What is the expected output? What do you see instead?
