I'm with thiago here,
module is not something we change all the time
like pages and components, it gets written bit by bit.
Naming conventions here don't speed-up development in scope
of the whole project.

I would even say it's faster because you can use autocomplete.

Subject: T5: how to insert string including markup
I have a use-case in which i need to catch a onchange of of select-component
on the server-side.
The only way I know how to do that is do a javascript
onchange='this.form.submit()' and catch the onsubmit() event on the
serverside.
This works well when i don't have a submit-component in the form

I would suggest that you use AJAX instead of doing the form submit.
Although the AJAX integration in T5 is still not implemented it's very
easy to do using the provided prototype and json javascripts. I did this
successfully for some simple events also.
Shortly, here's how i did it:

thanks that works partially.
However, the event is only catched twice:
1. on pageload (??m the sendRequest isn't called, but somehow the
getTheLink()-method is executed.)
2. the first time i send a onchange.
However after the first onchange all other onchange-event don't get
getTheLink()
That's the way it's supposed to be.
You only see the getTheLink method executed once because that what it
need to replace ${theLink} in your template with the correct link that
is returned from your method. This is done once when the page renders.
If you look at the rendered page source you
yeah indeed it is only called once when the template is rendered, I
discovered now.
However i don't need to return a dynamic url or whatever based on the
getTheLink-method.
what I need is a way to reliably catch a event at the server/java side (in
this case onChange) every time that event
The question is very relevant. The concern of the project should be to build
out the business functionality using existing tools. If the tools in
question are not yet released and in production, there is a very legitimate
concern that the maintenance of the tool will become a partial focus.
The method i suggested is implemented so that you don't have to submit
the form. That's what AJAX is all about, you make a request to the
server and then update a portion of your page based on the response from
the server using javascript. There's no page reload of for submission.

When the specific.tml page is requested, Tapestry asks its components to

The example i provided fires the call to the server whenever the

So, if you call the function from an onchange event on a select the
method will be called every time you change the selectbox.

Think of the element t:layout as a reference to your component, like

I must have been sleeping earlier, because I figured that (in your example)

It worked for me. Make sure you have created a Header class in your

Why do you say a redirect happens ? Does your page refresh when you
change the selectbox value ?
It won't refresh because all your doing is call a javascript function.
There's no redirect.
