gorm - Trouble uploading photo Grails -

I am following the Grails book in action Section 5.5 is an example of how to upload a photo in a user profile. Nothing complicated:

domain

  class profile {static belongsTo = user byte [] photo string fullname string bio string home page string email String Timezone String Country String jabberAddress string toString () {"Perfil para $ {fullName} ($ {id})"} Fixed constraints = {full name (faucet: true) Bio (faucet: true, maximum size: 1000) Homepage (Null: true, url: true) Email (null: true, email: true) photo (f): Country (faucet) True: time zone (tapable: true) jabberAddress (nullable: true, email: true)}   
}  
 Use profile and image controller code in the source While doing this, I am trying to upload a picture of this error (less than 10kb size):  
 The price for the column is too long "Photo Binari (255)"  
 I To accept a large byte [], you have tried several ways to change the definition of the column, including:  
 1) In the shortage of profiles, maxSize Setting: 1024 * 200 2) In profile mapping, setting the photo type: "Byte []", Length: 1024 * 200  
 The mapping of the t I have tried different combinations. SqlType: byte | Byte [] | Blob | Binary but either value is too long (for byte []) or other type (e.g., blob):  
 [B can not be cast on java.sql.blob  
 Please advise. Thanks!   
 
 
 While testing this, it was not working for me. I did not take any advantage of all static mapping and other answers. (Auto-generated) line at the top of the controller  
  @ Transaction (read only = true)   
 I was caught. Setting it to  false  has fixed the problem  
 To open these problems, insert a temporary  failOnError: true  in the method of saving One quick move i.e.  domainObject.save (failOnError: true)   
 I was normally using a service with writing access to save this image.
