Hi, We are facing a problem of converting Struts form beans to value objects and vice-versa. We use value objects as coarse grained data returned from the app tier. Value objects by virtue of their nature of representing persistent data, are immutable. Form beans on the other hand are more volatile and represent data that the user is changing. Hence they need to be separate implying a "conversion" of one unto the other during read and writes. When for instance, a set of value objects is read from the app tier before an update operation, the value objects need to be converted into Form beans to be edited by the user. One way to do the conversion is to localize the process at each form bean - however, we wanted to promote the conversion at a framework level. The generic conversion could be problematic in cases where deep hierarchies of value objects are encountered and more so in case where relations are one to many. Has any one in this list faced such a problem an are there any generic design patterns as a solution? Or am I making sense at all?
Thanx in advance, VD. __________________________________________________ Do You Yahoo!? Try FREE Yahoo! Mail - the world's greatest free email! http://mail.yahoo.com/ -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
