can't modify frozen hash

Hi,

When I upgraded my rails application to rails 2.3.2 I am getting error 'can't modify frozen hash' on using

@something.update_attribute(params[:something]). Can anyone help me who is familiarize with this bug?

Thanks,

Can you print the @something.frozen? in log file. If you are getting it as true, you may have to digg @something then. It seems not just the a record from database.

Thanks Srinivas
