RE: How to make drop down box from ArrayList
Hi Ulrich,
I am using Tapestry 5. I have made a drop down box using the ArrayList. I want
to fire an onChange event on my Page class and get some data relevant to the
selected option and display on another TextArea. Please check my code snippet
and let me know a way to that.
select t:id=importConditions onChange=javascript:filterOnChange();
t:loop source=filterList value=currentFilter
option value=${currentFilter}
${currentFilter}
/option
/t:loop
/select
Thanks,
Yees

Dave,
The Tapestry 5 Wiki help me a lot. It can be found at:

having a tough time finding any documentation on page templates; how to

I've started with the tutorial app, using v5.0.7, and am gradually
extending it. I've gotten the Spring integration working, which was very
simple once I began to understand what I had done wrong. So I'm able to
leverage my existing knowledge, and get data from a database. I do intend
to look at the Tapestry IOC way of doing things, but I'm starting with
little steps; that will come later.
So what I've got at this point is a Jobs.tml that I can access from the
Start.tml. Jobs.java gets a ServiceDao injected by Spring, and uses that to
retrieve a list of JobStatus for display. A JobStatus consists of a String
jobId, a String projectNumber, and a MapString,Status stages. A Status is
an enum, and the stages Map maps various job stages to the status of that
stage. I access the Status of a job stage by calling getStatus(String
stage) on the JobStatus object.
In Jobs.tml I have:
table

tr
thJob ID/th
thProject Number/th
thOutput Status/th
thShipment Info Posting/th
thBureau Code Posting/th
thInquiry Posting/th

td${jobStatus.jobId}/td
td${jobStatus.projectNumber}/td
td${outputStatus}/td
/tr
/tbody
/table
There are a couple of things about this that bother me. It seems that
Jobs.java is required to have a jobStatus property (with getter/setter) to
support the iteration (and for no other reason). I can get the output
status with ${outputStatus} by adding a getOutputStatus() method to
Jobs.java, which then invokes the getStatus(Output) method on the
required JobStatus property. But to me that smells (to use XP
terminology). It seems that a temp variable could be created to support the
iteration (ala JSF), and I would rather access the output status by
something like ${jobStatus.getStatus(Output)}, without requiring an
artificial method in Jobs.java, especially since it appears that I'll have
to add a number of other, similar, artificial methods for the other
statuses.
I realize that I may have a *lot* wrong above, and my hope is that someone
will (gently) point those errors out to me. Better yet would be to (again
gently) point me to documentation that will explain the above.
Thanks,

I think the new binding var (available from Tapestry
0.8 snapshot) is what you are looking for.
Document is available at the following.

There is also a post on this last week.

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?

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.

Uli

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.

I will try to read OGNL. For now, I did just as you suggested; created a

You can have a page method return the entire string, or read up on

[T5] NPE in PageRenderQueueImpl
Hi, I have a rather big application with hibernate integration that I am trying to deploy on a tomcat Server. After first deployment, I get the following error message almost for every page I go to. If I then just hit reload, the page loads correctly. I must touch every page maybe 2 or 3 time for the problem to dissappear. Then it won't re-appear anymore until I stop and start the server again. Anyone seen this before?

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

Re: T4: Newbie's questions
Hi Xiahong,
For Layout management, there is a example in Workbench demo:
src\Workbench\src\context\WEB-INF\Border.html
You may have better sense after you take a look of this page.

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.
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
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?
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.
Cheers,
Uli

[T4] AJAX: reender whole page or just send back the markup of the div
Dear all, I have a very basic question about AJAX in Tapestry 4.1.3: IIUC, the updateComponents attribute provided by Tapestry components works by rendering the *whole* page, extracting the relevant components (via their ids) and sending them back to the client. I find this very elegant and it makes the pages easy to maintain. For very complex pages, however, the above approach can result in some overhead. I'd therefore like to just call a function that returns the replacement div (and does not render the whole page). Is there a simple example that shows how to do this? For instance: Given a div and a link, clicking the link will replace the div via AJAX without reloading the page. Thanks, Kaspar P.S. I have started reading about EventListeners but am not sure whether this is exactly what I need. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tapestry 5.0.7 : Filtering in Output component
You will have to write your own component (a few lines), or add a JIRA issue so that we can work on providing this functionality.

How about a PERSESSION_SCOPE?
T5 now supports singleton and per-thread scope; in the webapps the per-session is also a good way! Any tips? -- Yet Another Java EE Developer!

Re: [T4] AJAX: reender whole page or just send back the markup of the div
Hi!
I don't think that Tapestry will render the whole page when a listener is in
invoked Asynchronously.
When you intend to define a link or form for Async invocation, remember to
set the async attribute as true
for example:
#DIV TO DISPLAY CURRENT TIME#
lt;span jwcid=[EMAIL PROTECTED] value=ognl:currentTime/
#LINK TO UPDATE CURRENT TIME PROPERTY#
lt;a jwcid=@DirectLink listener=listener:updateTime async=true
updateComponents=timeBar
What time is it?
#CORRESPONDING JAVA CODE#
public abstract Date getCurrentTime();
public abstract void setCurrentTime(Date time);
public void updateTime(){
this.setCurrentTime(new Date());
}
I think Tapestry Ajax basically updates client side page by component.
If you want to manipulate it by DOM element, you have to use EventListener
annotation
with the target to specify the DOM element you want to update
Please correct me if there is anything wrong

John
