Re: T5: passing values between layout component and page
Hi Ronald,
You can declare same ASO(ApplicationStateObject) in both java classes,
passing any values between any components.
Basic.java and UserProfile.java
...
@ApplicationState
private Visit _visit;
... getters and setters
Basic.tml
... ${visit.username}

hi ronaldlee,
you can pass the user name from the UserProfile page to the layout
component, something like this:
public class Layout {
@parameter
private String userName;
// getter/setter here
}
in UserProfile.tml:

T5: passing values between layout component and page
Hi,
I am building a page using layout component so that the layout can be shared
among other pages.
The question I have is that I want my layout component (lets say
"/layout/Basic.tml) to have access to page params/variables. A simple
example would be that I have a UserProfile page which uses a layout to
display the menu. I want that layout to also display the user name as
greeting ("Hi ${username}!). But the "username" is initialized in the page's
function (onActivate if is passed from another page, or other lifecycle
functions, or a "Persist("flash") variable..). So how my Basic.java can get
the username info (to be displayed in its Basic.tml) from the UserProfile
page? Same question for the opposite way (page gets values from layout
component).
thx!
Ronald

ContextResource getPath()
Hi, Is there any particular reason that ContextResource's getPath() returns a relative path rather than an absolute one? In T4, I'm used to using assets as way to build "safe" links to resources. With ContextResource's getPath() returning relative paths, however, that doesn't work. I've wrapped it to prepend a "/", which does take care of the issue. I'm just wondering if there's something else that I'm missing. Thanks, Kevin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[T5] BeanModel and null values
Hi all, I'm working with the Grid component and customizing the BeanModel for display. I'd like to show complex paths in the grid. So, I've added them to the model and everything works well, except when there's a null somewhere along the path. Then in get an NPE in the ConduitWrapper. How does one go about handling null values in this case? I'd like to just register a null value handler and have it spit out "Not Available" if a null value occurs at all in the property path. For what it's worth, I can handle it in the template by controlling the cell rendering. But, as soon as one tries to sort that column, the NPE is triggered again. Any help would be much appreciated.

[Tap 4.1.3] multiple ognl evaluation problem (was Re: [Tap 4.1.2] Problem with repeated calls to an If component)
Hi all,
I am on Tap 4.1.3 (using the released binary) and I am also experiencing
this behavior. I cannot find any documentation on this situation or a
workaround other than Jesse's comments in this thread. Can someone
point me to more information on how to work around this multiple ognl
evaluation? I am migrating a big application from Tap3 and I have lots
of legacy code that is currently broken because of this behavior.
Thank you,

hope there would be a way to turn it off via a flag, etc.
Does this "ensuring" feature only apply to IF components, or to others
as well? (i.e. are expressions for other components being evaluated
multiple times?) I have one dynamic form component that can make use
of up to 40 other core components based on multiple if/else
components.
I also feel assured now that this isn't some ill procedure that would
potentially break something down the line.

Re: T5: component expansion unexpected
You are ending the element before the inner (etc) renders.
Instead, you should end the writer in afterRender:
void afterRender(MarkupWriter writer)
{
writer.end(); //
}
The corelib components are good examples to copy.
Cheers,
Nick.

I attended a talk by Andy Hunt, of Pragmatic Programmers. They've found that the most powerful anti-piracy tools for their PDF books was: put the buyer's name in as text (and a watermark). Andy regularly checks P2P networks for copies of their books. On the rare, very rare, occasion that he finds one, he contacts the buyer and his experience, universally, has been that the file was offered up by accident and is immediately taken down. Andy agrees with most authors that PDF books spur dead tree sales, or fill a niche that was otherwise go unsold.

Re: General question regarding Web 2.0 and Tapestry
Hi, Same as you, no idea at all about this web 2.0. came from c/s world hoping web 2.0 can help in developing c/s like app, and after a while, found out that a server framework like T5, Javascript(or better a library like jQuery), html/css/DOM, plus the browser's capability to do background communication with server(xmlhttprequest) is enough to enable us to develop desktop like application, maybe that's web 2.0?

Getting BigDecimal Translator to work
I have written a BigDecimal translator which converts String -> BigDecimal,
but It doesnt seem to work.
In my class, I have added the following:
public static void contributeTranslatorDefaultSource(
MappedConfiguration configuration) {
configuration.add(BigDecimal.class, new BigDecimalTranslator());
}
public static void contributeTranslatorSource(
MappedConfiguration configuration) {
configuration.add("bigdecimal", new BigDecimalTranslator());
}
public static void contributeTypeCoercer(Configuration
configuration) {
Coercion to = new Coercion()
{
public BigDecimal coerce(String input) {
return new BigDecimal(input);
}
};
Coercion from = new Coercion()
{
public String coerce(BigDecimal input) {
return input.toString();
}
};
configuration.add(new CoercionTuple(String.class,
BigDecimal.class, to));
configuration.add(new CoercionTuple(BigDecimal.class, String.class, from));
}
any ideas what might be going wrong ? This translator doesnt seem to
register itself.
--Thanks.

Re: General question regarding Web 2.0 and Tapestry
I don't have a clear definition of web 2.0. THis is what wiki says Web 2.0 websites typically include some of these features: * Rich Internet application techniques, often Ajax-based * Semantically valid XHTML and HTML markup * Microformats enriching pages with additional semantics * Folksonomies (in the form of tags or tagclouds, for example) * Cascading Style Sheets to separate presentation from content * REST and/or XML- and/or JSON-based APIs * Syndication, aggregation and notification of data in RSS or Atom feeds * Mashups, merging content from different sources, client- and server-side * Weblog publishing tools * Wiki or forum software, etc., to support user generated content Thanks for your inputs.
