Can't insert nil values

[timhaines]

Have a column family with super columns. Trying to create columns with tweet ids as the key, and nil as the value. I get an error on .insert.

"Required field value is unset!"

Exception is raised from the CassandraThrift Column class's validate method
at Line 42 in vendor/gen-rb/cassandra_types.rb

Can you paste some actual code?
