jruby: text fields that precede integer fields clobber their values
Reported by Nick | September 10th, 2009 @ 02:20 PM
Either datamapper or data objects has some weird behavior on
jruby.
When an empty text field comes before an integer field in a select,
the integer field is clobbered.
require 'yaml'
require 'rubygems'
require 'dm-core'
class A
include DataMapper::Resource
property :id,Serial
property :txt,Text
end
DataMapper.setup :default,"mysql://root@localhost/testing"
DataMapper.auto_migrate!
A.create :txt=>'no clobbering time'
A.create
puts repository(:default).adapter.query('SELECT txt,id from `as`;').to_yaml
#from jruby
#---
#- !ruby/struct:#<Class:01x40395aaf>
# txt: no clobbering time
# id: 1
#- !ruby/struct:#<Class:01x40395aaf>
# txt:
# id: << ????
#MRI interpreter
#---
#- !ruby/struct:
# txt: !str:Extlib::ByteArray no clobbering time
# id: 1
#- !ruby/struct:
# txt:
# id: 2
Update
It also happens with string properties.

I'm not able to reproduce this issue:
--- - !ruby/struct:#<Class:01x1438dbe> txt: no clobbering time id: 1 - !ruby/struct:#<Class:01x1438dbe> txt: id: 2Can you let me know the versions of the following gems:
- do_mysql - do_jdbc - and JRuby itself(or did you install from source? in which case, please try pulling the latest code and seeing if its still occurring.)
Thanks!

This was happening using jruby 1.3.
Upgrading to jruby 1.3.1 fixed it.

Marking this as resolved due to new version of JRuby resolving the problem.
