I'm sorry I'm afraid I don't understand your situation. If you could
explain what exactly you are trying to do, maybe I can help.

Hi,
thanks for your answer. I tried with the loop, but I need to display only
one value. I think I could use the index parameter for Loop, but I don't see
how to link it with my List.

Here is an example, but how can I use it with my example ?
Thank you for your help !

This is a pretty basic operation that you can learn by doing the T5
tutorial.
It sounds like you want to enumerate a list and display something for
each iteration - a String property from each Fichier instance. To do
this you need the T5 Loop
<http://tapestry.apache.org/tapestry5/tapestry-core/component-parameters.html#orgapachetapestrycorelibcomponentsloop>
component. Your page provides the List (any Iterable), but must also
provide a property for holding a member of the List for each iteration
(the value parameter of the Loop). So in your page you need:
//The Iterable.
private ArrayList<Fichier> listeFichiers;
//The "current" element.
private Fichier fichier;
//now you need at least a getter for your list, and both a getter and a
setter for fichier.
In your template you can now:
<t:loop source="listeFichiers" value="fichier">
${fichier.field}
</t:loop>
Note that ${fichier.field} will result in a call to the method
Fichier#getField.

Hi,
I'd like to access the values of a List from my html page, but I don't
know
how to do that...
Start.java :
private ArrayList<Fichier> listeFichiers;
(getter/setter).
Start.html :
I want to display a field from Fichier (type String). But how can I
access
to it ? Is there a way to use such a ${listeFichiers...} with a parameter
?
Thank you for any help !
