hi everyone, i came across a very strange thing. i''m using ajax with jquery. when i build up the parameters as json i''m creating my data to pass like this : "{ picture: { photo: this.value, visible: 1, title: '''', description: '''' }, bla: '''' }" . as far as i know this should be the right json syntax. when i''m reading the params im my controller i''m getting this "{"bla"=>"", "id"=>"3", "picture"=>"[object Object]", "_"=>"1244292346625"}" as a consequence the stringfy_keys method is not found and i can''t process. does anyone have a clue what i''m missing and give me a hint? greetings, karl
