How to map a html field to a complicated property of page class in Tapestry5.0.4
Hi All,
There is a page class below.
// ProductDetail.java
private Goods _goods;
public void setGoods(Goods g) {
this._goods = g;
}
public Goods getGoods() {
Goods goods = new Goods();
goods.setDescription(Pure Cotton TShirt);
goods.setName(Pumpkin);
this._goods = goods;
}
...
// ProductDetail.html
input t:type=TextField t:id=goods.name class=form style=width:
220px; type=text /
I just want to map the text field to goods.name . Can I do it like above?
If not, what should I do?

Re: How to load a image dynamiclly in tapestry5.0.4
This is how I used Asset for an image in T5.0.4
Java class
@Inject

As result the img tag should look like ${product.image} or
I can use Asset to do it.
But I tried to do it using the first approach, exception occured.
And I don't know how to the second approach.
Can anyone give me an idea?

T4.1.1 Validation issue - clientside + decoration works, but getHasErrors is false?
I must be missing something very trivial here. I have a form with some 'required' validation specified, in the onSubmit I check for getHasErrors()==true. The strange thing is that this is always false, but the form *does* contain errors. What's more - the fields are properly decorated as having errors, and when I switch on client side validation - these errors are (also) picked up. So... why is it that getHasErrors() remains false?

May I use the tapestry-ioc other packages?
I try to use the Tapestry-ioc in the other packages,not just in the .pages.* package. Does it support this? I try to use @Inject in my domain.service.Impl.AccountServiceImpl.java code: @Inject private AccountDao dao; but it doesn't work! Any suggestion? 徐 依伟
Re: May I use the tapestry-ioc other packages?
You can create modules and use the IoC annotations to build services. However, the magic injection into private fields is part of Tapestry's very aggressive bytecode enhancement of component classes. It's not available for ordinary classes (I'd tend to call them data- or model-classes) outside of the controlled Tapestry packages (.pages, .components and .base). Basically, once Tapestry gets done working over a component class, it isn't good outside of Tapestry, it isn't even instantiable. For services, you place an org.apache.tapestry.ioc.annotations.Injectannotation on a parameter of your service implementation constructor. Or more likey, don't bother to annotate and Tapestry IoC will select the correct service or object to inject automatically.

Re: just posted some thoughts on tapestry and its future
And they are very good thoughts. There won't be a Tapestry 6. The design of Tapestry 5 is to create the stability you call for in your blog posting. The essence of Tapestry for me is that there is a fundamental germ of an idea encapsulated in the code and the design, and it's a powerful and compelling idea. Tapestry 1 through Tapestry 4 approached that idea and made it possible for many users to leverage it, but minor flaws in the implementation grew overwhelming, especially in terms of coloring outside the lines. My skill as a designer, as a coder, and (I hope) as an evangelist have all grown over the last few years, possibly as I've been exposed to other great developers (via the No Fluff Just Stuff conferences) and, through teaching Tapesry, to more actual users. My goal is to have something overwhelmingly compelling for new users, who are suffering under Struts and JSF, and for existing users (who need to make a transition from T4 to T5). The feedback I've been getting from my actual, paying clients is very positive, which keeps me motivated.

Re: How to load a image dynamiclly in tapestry5.0.4
In order to answer this question, some background is needed.
If you know the product's id (whatever you use, where it's SKU number or a
surrogate key) ... what is the exact process from going from that to a URL
suitable for an img tag?
That is ... are the images stored in the database? Or are they on the file
system somewhere? If they are files on the file system, are those files
mapped to a client-visible URL?
In the latter case, you can do something like:
img t:id=productImage src=prop:productImageURL/
public String getProductImageURL() {
return http://static.myco.com/product-images/; + _productId + .gif;
}
Assigning a t:id to a tag without specifying a component type creates an Any
component, a component that just renders whatever tag and informal
parameters you provide it. Here wer'e linking that to some Java code in the
corresponding page or component that computes the URL of the product based
on an instance variable. Probably your example is more complicated, but you
get the idea.
There's another approach used when the data is inside the database, but we
can dive into that if the above solution is insufficient.
Assets are useful for accessing resources inside the web application
context, or on the classpath, and includes logic related to localization ...
but it is not always appropriate when accessing resources that are well
outside the web application itself.

Yeah, that's how I'm doing this now. Having a Tapestry annotation like @Secure that invokes your pipeline contribution sounds the most solid.

looking for such a component
hi, all, I'm a novice to tapestry. And I wonder whether there is such a compenont. Generally, it acts like a table. But while table presents content this way: - row 1 - row 2 - row 3 - row 4 - I am looking for a component presents content this way: -+-- row 1 | row 2 -+-- row 3 | row 4 -+-- it puts the contest into grids, not rows. Is there any conponents like this? thank you!
RE: looking for such a component
Have you considered a simple @For and then use CSS and display:block,
float:left to generate the positioning?
It looks like you are wanting a multi-column display of a list, rather than
a real table. Play around with
ul class=mylist
lirow 1/li
lirow 2/li
... etc.
/ul
And in css:
ul.mylist li {
display:block;
float:left;
width: 50px;
}
You will render the list horizontally until you hit a containing element, so
if you have the list inside a fixed-width div, then you can limit the
number horizontally. You will also need to play with padding and margins in
your css.

Re: looking for such a component
hi, Jonathan, thank you. That's what I am trying to do now. As I have ever used JSF and it has a table component which can designate its style to ask it display rows as grids, I do know whether tap has such a component, so I post this email. Still thanks for your help. Your demo helps me with this For component!
Re: How to load a image dynamiclly in tapestry5.0.4
Thank you very much. My image file is put on file system. It works now.
But I feel that it's not flexible.
I wrote the img tag like
img t:id=productImage src=prop:productImageURL/
But I want write it like
img t:id=productImage src=/products_images/prop:productImageURL/
You see, there is a folder prefix for the src property of img tag above
For this efffect, what should I do?

Re: How to load a image dynamiclly in tapestry5.0.4
Wait for 5.0.5 ... I'm working on code for that right now, so you'll be able
to write:
img src=/products_images/${productImageURL}/
Still, from a maintainability situation, I would prefer that the complete
URL come from the Java code side; if /product_images ever becomes, say,
/images/catalog some day, you may be able to fix it across your entire
application in exactly one place. That's the Dont Repeat Yourself principle
and your example jumps out at me as a potential problem.
