T4: Newbie's questions
Hi,
I am exploring Tapestry (currently looking at 4.1.4 snapshot). So far,
the experience has been very positive. I was able to convert a Struts
based application to Tapestry4 in just a couple days. However, I still
need answer to the following questions,
1) Layout management: I couldn't find a documented solution to replace
tiles used by the old application.
2) Dynamic attribute value generation: Something like the following you
can do with JSP
input type=submit value=${button. value}/
How do I achieve this in Tapestry? Is there a component I can use to
generate dynamic content as value for any arbitrary attribute of an HTML
element?

Not sure on that one, I don't believe there really is anything
dealing with layout other than a table.

The Any component is what you want, I believe:
input jwcid=@Any type=submit value=ognl:value/

I'm no Struts expert but AFAICR tiles are just some kind of reusable
templates. In Tapestry every component you write can be compared with a
tile. Just write your component (with or without a template) and reuse
it anywhere in your projects.
To manage a common layout on all pages you write a so called Border
component which contains layout common to all pages and that contains
the RenderBody component. If you then wrap your page's components within
your Border component, the content of your Border component is
rendered around them. Look here for an example:
http://tapestry.apache.org/tapestry4.1/components/general/renderbody.html

In Tapestry you do that with some OGNL expression. Your example would be
something like input jwcid=@Submit value=ognl:pageProperty / which
would label your button according to a call of getPageProperty() on your
page class.

Hi Zheng, Since you are newbie, I think you should try T5. I'm a Tapestry user since T3. T5 is more intuitive and easy to learn, in my opinion. Marcus

http://tapestry.apache.org/tapestry4.1/components/general/renderbody.html
One thing that may be complicating things for people with Tiles experience
is to wrap their heads around the fact that you really aren't managing page
snippets, but complete page templates in Tapestry, in other words a Tapestry
page template combines both a Tiles definition and an individiual Tiles page
snippet into one; an approach similar to Facelets. So a Tapestry page
typically always starts with a Border component of your choice (equal to a
Tiles layout definition), containing the body of the page, which the Border
component (template) then injects to an appropriate place with the help of a
Body component to produce the rendered page. What you loose compared to
Tiles is that you have to declare a Border for each page, but you get it
back with the additional flexibility of being able to easily use and switch
to different Borders and the page itself documenting which layout it's
currently using.

You can have a page method return the entire string, or read up on
OGNL. It can do string concatenation.

Re: T4: Newbie's questions
Which doesn't work if you want to include a single quote in the
string, as he seems to want. You can get around this by defining the
component in the .page file and specifying that property like this:
component id=attributesDisplay type=Insert
binding name=value
value=components.table.columnValue /
binding name=renderTag value=literal:true /
binding name=width value=literal:100% /
binding name=onmouseover
return escape(hintAttributesTxt(1,this,'+attrList
+'))
/binding
/component

Hi Xiahong,
For Layout management, there is a example in Workbench demo:

You may have better sense after you take a look of this page.
