Affects Version/s: 5.0.6
Fix Version/s: None
Environment:Safari, OS X, JBoss 4.2.1
The user loses the changes they typed into an "input" or "edit" page if an error is recorded by onSuccess() AND the page is dealing with a client persisted object. The page is redisplayed OK, with error, but with the previous values!!!
The user's changes aren't lost if
(a) I move the work that finds the error from onSuccess() into onValidate() - this fixes all TextField components but does not fix Select, DateField, checkbox, or expansions; or
(b) I add a simple client-persisted field to the page - remarkably this fixes; or
(c) I replace client persistence with session persistence.
To illustrate the problem, it's just like the example from http://tapestry.apache.org/tapestry5/tapestry-core/guide/validation.html, which contains these excerpts:
private String _userName;
private String _password;
if (!_authenticator.isValid(_userName, _password))
except that instead of a single field, _userName, I am persisting a whole object, _user:
private User _user;
and in the template we refer to its fields, eg:
<input t:type="TextField" t:id="firstName" value="user.firstName" ...
If the user types a value into firstName, but the onSuccess() method records an error, then the user loses what they typed.
However, if I add another field to the page then everything works!
private String _aField;
<input t:type="TextField" t:id="aField" value="aField" ...
Alternatively, it works if I do either of the other 2 things - use session persistence or move all logic into onValidate().
