t:if test considers Float < 1.0 as false?
It seems that t:if considers 0.1, 0.99 as false, but 1.0 as true. Should I file a bug? This is 5.0.18 -james -- James A. Hillyerd
Re: [T5] improve documentation
I quite like the existing tutorial, I was just disappointed it ended so abruptly. :) I think whatever docs come around in the future, they need to cover more on Encoders/Translators/Coercers - as that was one of the most difficult things for me to learn. Honestly, I still barely understand when to use which. -james On Tue, Jan 13, 2009 at 10:15 AM, Howard Lewis Ship wrote: > I've been coming to the same conclusion. > > I'm clearing time with my boss to pursue this, along with several > online articles. > > I have an idea for an application that can demonstrate every bit of > Tapestry and be useful to boot. > > So the "guide" is the reference, what I have planned is the "tour". > It would replace the tutorial. > > > -- James A.

Google and t:grid
Google is indexing the different sorted versions of my grid components. ie: http://simobjects.net/manufacturer/view.grid.columns:sort/aircraftType?t:ac=5 This makes it look like I have a bunch of pages with identical content, which google doesn't like. It also makes the site more brittle, because in some places I have renamed the grid, so the link returns an error. (The above link is an example of that) It seems like adding rel="nofollow" to the sort links would be a good idea? -james -- James A. Hillyerd
tapestry:parameter namespace
I've tried using the xmlns:p="tapestry:parameter" namespace a couple times, but it doesn't seem to work. Also, the manual says t:parameter is deprecated, but then says that the new namespace was introduced in Tapestry 5.1 - which I don't think exists yet? Any ideas? >From the manual: Parameter Namespace Parameter namespaces are a new feature introduced in Tapestry 5.1. They are a more concise way of passing parameter blocks to components. You must define a special namespace, usually given the prefix "p": http://tapestry.apache.org/schema/tapestry_5_0_0.xsd"; xmlns:p="tapestry:parameter"> -james -- James A.

Gotta say, it's really confusing that @InjectService doesn't work with

Re: What's the easiest way to implement two dependent select lists ?
Hugo,
That's a great example. I think this belongs on the Wiki!
Is the JSON stuff built into Tapestry, or do I need a third party library
for that?

Re: passivate/activate
(I'm still learning to anyone feel free to correct me!)
Think of it this way: onPassivate() is used to generate links to your a
page. Anytime you to t:pagelink, t:actionlink, or t:form - they all create
an instance of your page (even if you don't specify a context), then call
onPassivate on it. I *think* each link/form etc will create it's own
instance of the page (actually more likely fetching it from the cache) and
call onPassivate. So you could see this many times for a single .tml
render.
onActivate() doesn't necessarily need to be called first. You could @Inject
a page, call a setter on it, and then return it from an event handler. I
think Tapestry would then call onPassivate and use that to generate the
redirect URL for the browser. Then when your browser requests that URL,
Tapestry will call the pages onActivate method to attempt restore the state
you wanted.
Does that make sense? I know the labeling seems backwards, that's what made
it hard for me to grasp - seems weird to passivate something that was never
activated!

Re: Page present, still get onLoad FAIL: ClassNotFound error
You will probably want to scroll down further in the stack trace. If Tapestry IoC can't resolve everything it needs to inject into a particular Page, Component or Service then you will see ClassNotFoundException. It's likely the JVM was able to load the class fine. -james On Fri, Dec 5, 2008 at 10:08 AM, Tom Pfotzer <[EMAIL PROTECTED]>wrote: > > I'm new to Tapestry.

Advantages of various .tml storage locations?
What are the pros/cons of keeping page .tml in: 1. src/main/java vs 2. src/main/resources vs 3. src/main/webapp ? I see JumpStart uses #1, and the tutorial uses #3. Seems like it would easier to use #1 or #2 so at least the components and pages .tml are in the same directory tree. Thanks. -james -- James A. Hillyerd <[EMAIL PROTECTED]>
