RE: Submitting id value of a t:select component onChange
If you are generating a placeholder serverside and replacing it clientside, there's no need to use a request parameter. You can just use the event context. You only need a request parameter when appending to the URL in javascript rather than replacing a token. Note that if you have ValueEncoders registered for your types, you don't need to worry about String / Integer id's… you can use your domain objects / enums etc instead and let tapestry do the conversion for you.
PageActivationContext issue
Hi,
I have the following code:
class Page1 {
@InjectPage
private Page2 page2;
...
Object onSuccessFrom...() {
...
ListCat catList = new ArrayList...
catList.add(cat1);
catList.add(cat2);
page2.setCatList(catList);
return page2;
}
}
class Page2 {
@PageActivationContext
@Property(write = false)
private ListCat catList;
public void setBaList(ListCat catList) {
this.catList= catList;
}
void onActivate() {
//catList is null
}
void onActivate(ListCat catList)
{
//catList is null
}
void setupRender() {
//catList is null
}
}
If I replace @PageActivationContext with @Persist, I see the list populated,
but I don't understand how should I use the @PageActivationContext

Re: PageActivationContext issue
I think I had issues trying to use an array / collection as an EventContext
item. I think I had to resort to using a comma separated string from
memory.

Re: PageActivationContext issue
In your case, I think you will be able to fix it by. 1. Remove @PageActivationContext 2. Add onActivate(EventContext ec) 3. Add ListCat onPassivate() On 22 Aug 2013 15:18, Lance Java lance.j...@googlemail.com wrote: I think I had issues trying to use an array / collection as an EventContext item.

How to implement simple error/exception handling
Hi,
I read about exceptions and error handling in tapestry, but still can not find
the best way, to send messages to front-end. I want to be able to send
exception messages and error codes, as I can do it in jquary ajax success or
error blocks. When I throw some custom exception I don't want to redirect to
the exception page, but to show the message in pop-up to the user. Or to send
different completion messages and to display them in dialogs. I managed to open
dialogs with callbacks of ajax object as here:
ajaxResponseRenderer.addCallback(new JavaScriptCallback() {
@Override
public void run(JavaScriptSupport
javaScriptSupport) {
javaScriptSupport.addScript(showErrorModal(););
}
})
, but still can not make it enough generic. And it is not working working when
I submit the whole page.

Re: How to implement simple error/exception handling
This is outside the scope of Tapestry (or at least as far as I am aware
off). Take a look at this example:
http://jumpstart.doublenegative.com.au/jumpstart/together/easycrud/persons
If you hit the Delete on any row it opens a modal dialog asking you whether
or not the item should be really deleted. In your case you need a info box
with a meaningful Information message explaining the error to the user.
You can use jQuery UI for this (check the jQuery for Tapestry modul) or use
what they used in the above example. The Keypart is confirm.js here.
If you need a tapestry only usage you might want to consider a component /
mixin that is returned in case of a XHR request (ajax) and opens the
infobox and vanishes (removes itself from the DOM) after the ok button was
clicked. I dont know if such a component exist and the use would be limited
to zone updates and alike. Also I am not aware of Tapestry providing such a
component (or something similar).
Lets wait what the Tapestry Pros come up with.

TransactionHandling
Hi there, I just wonder how Tapestry handles nested transactions. From the @CommitAfter annotation one learns that there is no such detection unless we are using a PersistenceContext. This seams to be unimpropriated. I want something like this (Similar to the Spring transactional annotation). I want a method to define a transaction by begin on start and commit / roolback on the end. If a method is called doing the same the inner 'transaction' is treated as part of the outertransaction so actually it is ignoredl Currently @CommitAfter is definied to commit the transaction on the end of the mehtod. Since there is a PersistenceContext, I asked myself if I can get the ignore inner transaction pattern? Thanks, Martin (Kersten), Germany
[ANNOUNCEMENT] tynamo-federatedaccounts 0.4.3 released!
Federatedaccounts takes another leap forward by integrating with a new, Scribe-based module, Pac4j by Jérôme Leleu https://github.com/leleuj/pac4j. See, the problem with Scribe, and Oauth in general, is that there's no standard way of getting any unique identifier with Oauth (unlike in OpenID). So there are several different provider specific extension and it quickly becomes a mess (read what the author of Scribe thinks about thishttps://github.com/fernandezpablo85/scribe-java/wiki/Scribe-scope-revised). Anyway, it's great somebody, and in this case, Jérôme, still bothers to generalize the approach because otherwise I would have needed to do it. The new Federated Accounts module, tynamo-federatedaccounts-pac4jbasedoauth, simply provides UI components (Oauth sign in components, callback pages) around Pac4j, handles the Oauth all automatically and bakes in Tapestry-style configuration around it so all you need to do is to just add your Oauth app credentials for your provider of choice. The primary use case for the new module is authentication and user profile federation, for other uses cases, you typically still want to use provider specific APIs and libraries. Documentation is also updated although a bit thin still. Read more at tynamo-federatedaccounts guidehttp://docs.codehaus.org/display/TYNAMO/tynamo-federatedaccounts+guide . Release notes: Improvement - [TYNAMO-211 http://jira.codehaus.org/browse/TYNAMO-211] - Allow parametrized configuration in federated login components for setting rememberMe in the token - [TYNAMO-220 http://jira.codehaus.org/browse/TYNAMO-220] - Implement rolling tokens support for federated accounts - [TYNAMO-181 http://jira.codehaus.org/browse/TYNAMO-181] - Implement DefaultJpaFederatedAccountServiceImpl - [TYNAMO-182 http://jira.codehaus.org/browse/TYNAMO-182] - Support GitHub federated login New Feature - [TYNAMO-93 http://jira.codehaus.org/browse/TYNAMO-93] - Support for Google OAuth 2.0 Bug - [TYNAMO-217 http://jira.codehaus.org/browse/TYNAMO-217] - returnPageName is required since there's no defaultReturnPage prop in AbstractOauthSignIn Enjoy, Tynamo Team
