Re: A more general approach to configuring for compatibility
I'm not familiar with Tapestry code but that sounds like a lot of if's and checking for version. If i'm not mistaken then it will pollute the code and maybe slow down applications (as every action will need to be checked) If it is possible then additional modules sounds as much better idea. If someone is upgrading library version then some minimal effort is required from his side (downloading new jar/changing maven). Some small additional effort (downloading second jar/adding maven dependency) should not be so exhausting, and will allow to avoid a lot of unnecessary code.

In library service module there should be options that could set what is being uploaded to tapestry public repository.

Re: [T5.2] Constructor issue
I must disagree. But first to clarify. I described two cases. 1. BeanEditForm that cannot instantiate my object 2. Same issue for SSO creating java.util.Date AD 1. Quote from BeanEditForm doc: "Often, the BeanEditForm can create the object as needed (assuming a public, no arguments constructor). " So i provided such constructor in my entity (public no agrs) + I added another one that taken String and custom enum. What I assumed was that T5 will just use the one that it can use and leave other one alone. Due to that behavior no object handled to BeanEditForm should have more constructors than default one, or should be always created manually, and that is bit more than user need to do. Ad 2. Quote from linked documentation: "The first time you access an SSO, it is created automatically. Typically, the SSO will have a public no-args constructor ... but you may inject dependencies into the SSO via its constructor, as you can with a Tapestry IoC service implementation." In this case I wanted to use Date. Maybe not some real case scenario, so let's think about shoping basket for example. It may have default no args for T5 and second one if I want to instantiate it with some products. If T5 always takes constructor with most arguments it will fail on that scenario also, meaning that I will have to check boolean variable companion exist on every page on which I wan't to use my object. IMHO the best would be try to use no-args constructor or use one with most args and if You fail try another one and another till You succeed (meaning reach default no-args or error when there is no default no-args constructor).

[T5.2] Constructor issue
Hi all. While preparing small showcase app, odd problem came out. When I created domain object with two constructors (first was default NOOP, second one had two parameters string and enum, it was meant for manual initialization only) and tried to use it with beaneditform I received exception that tapestry cannot handle my object creation. After removing parametrized constructor, error disappeared. It's bit odd IMHO. Tapestry should be capable to instantiate objects that have more than one constructor. Also @SessionState behaved weirdly. I was annotating java.util.Date. Error came up if I haven't instantiate object manually. Date has default constructor so Tapestry should be fine with constructing new Date on it's own. Maybe there are some reasons for that kind of behavior, but as I see it those are bugs. Should I create jira ticket for that? Tested on tapestry 5.2.1-snapshot.

Re: Another IllegalAccessError in 5.2 alpha [bug?]
I'm not everyday Tapestry user but I try to 'evangelize' in my neighborhood.
In April I given presentation about Tapestry on tricity JUG and in next
couple of weeks I'm planning to do another one. During first presentation I
told that T5 won't change in a way that will affect existing code and with
new version there is feature that makes me a liar ;) After long introduction
I have proposal. Maybe it would be best for T5 if there would be option in
MappedConfiguration that would turn on/off live reloading on all methods,
something like:
configuration.add(SymbolConstants.ENABLE_LIVE_RELOADING, "true/false");
with possibility to add the .preventReloading()/.enableReloading() on
services that should behave in other way. Thanks to that You are backward
compatible (what is IMO the most important thing for tapestry currently) and
in easy way one may use new features on his own responsibility.
Of course I don't know if it is possible to implement that kind of feature
but it would show that T5 is really going to develop in a way that won't
harm any already existing applications. (or maybe that bug is simple to
resolve and all that I wrote is not relevant :) )

Validation in component using onValidate method
Hi all,
I'm using tapestry for some time but for first time I cannot find correct
solution by myself. My problem is with validation in onValidate method. I
get that onValidate is called for every component inside form and
onValidateForm is called after all other onValidates but I don't get why
first Tapestery generates validate event and only after that it calls setter
method for validated property.
As I always could call onValidateForm, then it wasn't such a problem, but
currently I need to do validation from inside of component. Structure is
following: Page contains form and component which is just a part of that
form. Component contains just a textarea, so validateForm method is not
called. IMHO onValidateFromMyField method should do the job but inside I
always get null. About year ago I was putting hidden field inside the form,
but it's wasn't the solution and it definitely wasn't reliable. I always
could find some simple workaround, but now the only solution that I see, is
to make whole validation inside page validateForm method, what would result
in violation of DRY principle (b/c I would have to do same trick in every
page that uses my component). Project in which I have this problem is
relatively small, so I could implement this workaround, but everything in me
opose to do that (because of the smell it would left, and feeling that some
day it won't be a small project).
As my english is not the best I prepared small example which should be more
expressive than my explanation.
1. Page class
@Property
@Persist
private String foo;
@Property
@Persist
private String bar;
@Inject
private Logger log;
@Inject
private ComponentResources resources;
@Log
public void onValidateForm() throws ValidationException {
log.debug("");
log.debug("foo '{}', bar '{}'", foo, bar);
}
@Log
void onSuccess() {
resources.discardPersistentFieldChanges();
}
2. tml file for that page
3. component code
@Inject
private Logger log;
@Persist
private String password;
@Log
void onValidateFromPasswordComponent() throws
ValidationException {
log.debug("Password '{}'", password);
// do validation, if goes wrong throw new
// ValidationException(recordedError);
}
@Log
void onValidate() throws ValidationException {
log.debug("Password '{}'", password);
// do validation, if goes wrong throw new
// ValidationException(recordedError);
}
@Log
public void setPassword(String password) {
this.password = password;
}
@Log
public String getPassword() {
return password;
}
http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xmlns:p="tapestry:parameter">
4. Log from submit. Values inputed into fields were a, b, c:
[DEBUG] components.Comp [ENTER] onValidate()
[DEBUG] components.Comp Password 'null'
[DEBUG] components.Comp [ EXIT] onValidate
[DEBUG] components.Comp [ENTER] onValidateFromPasswordComponent()
[DEBUG] components.Comp Password 'null'
[DEBUG] components.Comp [ EXIT] onValidateFromPasswordComponent
[DEBUG] components.Comp [ENTER] setPassword("c")
[DEBUG] components.Comp [ EXIT] setPassword
[DEBUG] pages.About [ENTER] onValidateForm()
[DEBUG] pages.About
[DEBUG] pages.About foo 'a', bar 'b'
[DEBUG] pages.About [ EXIT] onValidateForm
[DEBUG] pages.About [ENTER] onSuccess()
[DEBUG] pages.About [ EXIT] onSuccess
IMHO it is bug or really counterintuitive feature. How I am supposed to do
validation when value is always null?
Please help, I really want to do this properly.

Michał Gruca
