Re: T5: How to bind composite class' field(like sale.product.price) in page template

[smithfox]

I do more test based you simple.
Yes, a nested class also work.

As you said: It's not tapestry issue.

Your code is:
[Page.java]
private BznsPojo pojo= new BznsPojo();

My code is:
[Page.java]
private BznsPojo pojo;

@BeginRender
void beginRender(){
  pojo = createNewPojo();
}

private BznsPojo createNewPojo(){
  BznsPojo pojo = new BznsPojo();
  Product product = new Product();
  pojo.setProduct(product);
  return pojo;
}


So the problem is caused by lifecycle of pojo:
I guess that  pojo's nested field object have already referenced by page
template before BeginRender( and SteupRender) event.

So I change the code:

My code is:
[Page.java]
@Retain
private BznsPojo pojo;

.....


OK, It work.

Thank for Filip's help.
