Actually... on second thought you can't return null from add since tapestry
needs to render the empty record.
Try this instead:
eg:
...
public class NullNewValueEncoder implements ValueEncoder {
private static final String CLIENT_NULL = "XXX";
private ValueEncoder encoder;
private Class
I agree with Thiago: "My best practices for persisting fields is this: just do
it when there's no way of avoiding it."
Most JumpStart examples avoid @Persist. The reasons are given in the "Caution"
section of this page:
http://jumpstart.doublenegative.com.au/jumpstart7/examples/state/s
Thinking about this a bit more, you can probably avoid @Persist by using an
appropriate ValueEncoder.
eg:
...
public class LazyValueEncoder implements ValueEncoder {
private static final String CLIENT_NULL = "XXX";
private ValueEncoder encoder;
private Class type;
public LazyValueEnco
There's really 3 options:
1. Use the HttpSession
2. Save to the database and pass ids (perhaps a staging table or status=
temp)
3. Store values on the client (hidden fields, data attributes, javascript
variables, activation context, request parameters)

Hi,
each time on a submit failed the field values associated to a simple string
persist without requiring @Persist annotation. But when you have any other
type of fields, for example a list from an ajaxformloop, or a file
selection, their values doesn't persist naturally, you have to use @Persist
