Does the edit form ... and that field in particular ... get pre-populated?  
If so, the existing value should be what is submitted.

But I'm a bit vague about SQLFORM.grid(), so I'm not going to be much help.

{Disarmed} Re: {Disarmed} [web2py] Re: grid IS_IMAGE validator behavior

[Carlos Cesar Caballero Díaz]

That's the issue, I don't want null values, the user shouldn't remove 
the image without upload a new one, but when I use the grid's edit form, 
the validation error is triggered if the user edit another field, so the 
form can't be submitted without uploading a new image.

often, now I am using the IS_IMAGE, but using the grid on edit it's
throwing a validation error if the user don't set a new image.

It's a bug or is the default behavior?
