[web2py] Invalid Data causes all Check Boxes to be selected

[Michael Howden]

Hello,

I have a field:
opt_severity = {1:T("Minor"),
                2:T("Significant"),
                3:T("Major"),
                4:T("Catastrophic")
                }

table.severity.requires = IS_IN_SET(opt_severity)
table.severity.widget = CheckboxesWidget.widget    

If there is invalid data in another field, then the form will reload with
all of the check boxes selected :(

This also happens in a custom check box widget I designed.

Any ideas?

Cheers

Michael
