[T5] Looping over strings
Hi all,
I've got the following in my Init.html:
${subdirectory}
which nicely generates a list of links. The subdirectory parameter is
a string (i.e. directory.options is a List, a list of
subdirectories).
In Init.java I have
public void onActionFromSubdir(final String subdirectory) {
System.out.println("subdirectory='" + subdirectory + "'");
}
which gets called when I click on one of the above links. However, the
subdirectory parameter is always empty (""). In the T5 tutorial with
integers this worked perfectly. What am I doing wrong?
On top of that I'm getting a warning:
[WARN] ResourceCache Alias request of
'file:/...dirs.../src/main/webapp/init.subdir/the/sub/dir' for
'file:/...dirs.../src/main/webapp/init.subdir/the/sub/dir'
(when selecting /the/sub/dir link). How can I suppress this?
Cheers,
Hilco

Re: How can I use javascript in html template with TP5.0.4
I tried it.But it still don't work. Even it can work, I think this is also not good. Becuase it make writting javascript in html template becomes so complex. I remember in T4, I can add a same .script file with page class then write javascript in it. Can I do it like above in T5?

Re: T5 Invoke ValidationTracker recordError with elementName instead of Field
Does this enable us to use hibernate validator in our business layer
that is completely independent from tapestry?
Hibernate validator is right now our favorite option for validation,
but it might be that we have to use an own implementation - we're still
evaluating.
What we're sure about is that in the business layer validation is
performed and that for each validation error details are provided
that should allow the presentation layer to map this information
to a specific field/element.
IMHO a good solution for this use case is recording the error with
the element name, without being forced to have a Field for each
element.
What do you think?
Cheers,
Martin

Re: T5: Dynamic components (Dynamic Tiles)
Here we go again ... Tapestry pages a very structured, in effect, static. This is core to Tapestry's approach towards scalability and maintenance of server side state. However, even though the page structure is static, the order in which components render is really under your control. Further, you can mix and match rendering of components from different pages. A render phase method is allowed to return a Block or a component or anything else that knows how to render, and that object will then take control of the rendering. This is how the BeanEditForm and Grid components operate; there are extra pages that contain components for different types of edittable data, and the BeanEditForm or Grid just chooses the correct Block of components to render based on the type of property being editted. I hope to flesh this out in a more advanced chapter of the tutorial. I'm currently converting it from PDF to HTML to allow more people to contribute to it.

Re: T5 endorsement
That's great to hear. I agree that the documentation needs a little work about layout, we're relying on the crutch of saying "use the standard Maven layout". Of course, there's nothing in Tapestry that requires that exact layout. There has certainly been some interest from a few different directions on a Tapestry 5 book!

Re: T5 Invoke ValidationTracker recordError with elementName instead of Field
We want to do validation in the business layer (with hibernate
validator) and get back an exception with a list of invalid values,
where each invalid value provides the property path.
Then we want to have a mapping of the property path to the element
name and record an error for this on the tapestry form.
The value is to be able to use hibernate validator in our business
layer and not to be forced to define each Field in the page class,
which is better in terms of performance and saves unnecessary work.

I don't see the value ... how would you obtain the element name
without getting the field itself; and if you've injected the field (to
invoke getElementName() ), then why wouldn't you just pass the field
to the tracker?
Convince me there's something actually missing.
