The issue I'm seeing right now with lazily-loaded properties is that they're loaded when using BeanUtils.copyProperties() is called. I use this to convert POJOs to ActionForms, and consequently the {{getResumes()}} method is called. However, I don't want this. I'd rather the getResumes() method is called when I call it in my code (rather than by a 3rd party conversion utility). Therefore, I'm thinking that passing the POJO to the view is the best solution. Because I'm using the [open-session-in-view pattern|http://hibernate.bluemars.net/43.htm], those lazy collections are still available while the JSP is being rendered.

''Are you saying that you would populate the form manually in the view?'' ~ [mojavelinux]

I suggest looking at Struts' __Nested__ taglib. It does set properties if complex DTO objects

and does not require (semi)manual conversion between strings and actual data types.

With little wrapper to BeanUtilities, which registers a Date handler with desired formatting pattern, it allows correct handling of dates.

I know it's not really useful to you, but WebWork gives you this natively. It's one of the big differences between WW and Struts, in that with WebWork you can make true model-driven actions, and then use them in your form.

For example a form field called
