you could use hidden variables on your jsp page to store the VO attributes you are not changing and keep your VO intact only changing the 5 fields

Hi Darren, I was under the impression that it works exactly the way you hope it does. Actually I'm pretty sure it does. Also what might be worth looking at ( I have to look at it myself ), is Light-value-objects where you only populate the initial value object with the 5 fields rather than the whole 20. This is obviously more optimal in terms of db queries. This is all pre-supposing you are using xdoclet and EJBs and xdoclet, which perhaps you are not.

Been working with struts and value-objects, and I am beginning to understand the power of these two in combination. I did however run into a snag that may be either on purpose or just ignorance on my part. If I pass a 20-field value-object to an ActionForm (let's say an EmployeeVO), and I only show the employee's name and address for editing (only 5 or so fields). They make the necessary changes and submit the form. What I understand is the form will populate a NEW EmployeeVO and not make the changes to the original EmployeeVO, thereby creating an EmployeeVO populated only from the 5 fields on the form and nulling the other 15 fields. I was hoping to take an existing Value-Object, only make necessary changes from the submitted form (i.e. 0-5 changed fields and the other 15 stay the way they are), and then re-submit the Value-Object for updating the DB, but that does not seem possible. Am I doing something wrong and/or mis-understanding the best utilization of Value-Objects with Struts? Again, I'm a newbie so any pointers, help, or examples would be great! thanky in advance! -D --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
