[T5] Access table values from html
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 !

Hi :)
It seems I'm not very clear, sorry for my english...
As I answered to Chris, I'd like to display all the elements on the same
page, but in different tables, that's why I can't tell my page before which
element to render...
Anyway, your explanation is very clear :)
Thank you

Re: [T5] Access table values from html
Posted by Kristian Marinkovic <kr...@porsche.co.at>.
i still do not understand what you want to do but i'll try to
provide some usful explanations :)
if you have a list of elements you can render them using
a Loop component. The Loop component (see Component
Reference) provides the source parameter to pass in the
list (or another collection). The Loop component also
provides a value (Object) and an index (int) parameter.
During the loop the variables referenced through the index and
value parameter will be updated with the current iteration count and
with the object via their setter methods. So if you also provide
getter methods for these variables you can access them in your
template.
OGNL was used in T4 and provided means to access and return
an object from a list by directly providing an index in the template
or the .page file. This is not possible with T5s prop binding (eventually
will provide this functionality -> see JIRA).
so if you know beforehand what object you need to can provide a
getter method for it

Re: [T5] Access table values from html
Ok, in fact I want all the objects from the list, but not in the same
table,
that's why I dont think a Loop is usuable, because I won't display them
one
after the other.
But even if I provide a getter for my object, I don't think I can tell my
page which object for the List to render (because it changes).
Now, I have instanciated all the 15 Objects of the list, and I provide 15
getters... But I don't think it's very optimal !!
Thanks a lot for your help Chris !!

Re: [T5] Access table values from html
Posted by lasitha <la...@gmail.com>.
Hi, i'm joining this thread rather late, so i apologize for any
repetition - if you've already come up with a clean (!= 15 getters!)
solution, feel free to ignore this.
I'm trying to understand what makes your problem more complicated than
a typical loop...
It sounds to me like each table represents something _more_ than can
be represented by a single Fichier instance. Is that true? In other
words, is there information presented in a table that is not available
in the corresponding Fichier? I ask this because in your example, one
of the columns has the hardcoded value 'Fichier 50': is this string
something that can't be encapsulated by the corresponding Fichier
instance?
If this is the case, is there some 'larger' class you might come up
with that encapsulates both the data in the Fichier and the other data
presented in the table? If there is a single object that contains all
the data to be presented on one table, then your problem is reduced to
a simple loop.
I could be completely misunderstanding the problem, but i thought i'd
throw this out and see if i hit anything :)
Cheers,
lasitha.

Yes , I will use a loop to generate my tables... But I have 2 or more objects
to display in each table...
Anyway, I think I'm going to find a solution !

Re: [T5] Access table values from html
Posted by Chris Lewis <ch...@bellsouth.net>.
Using loop you can create a new table for each object, so if you want to
display them all, this is what you want. If you want only one, then you
should know which before hand and make it available to the template via
a getter.

Re: [T5] Access table values from html
Posted by Hibowl <ju...@gmail.com>.
Yes, it's quite ridiculous :) But I needed to test...
My page should display all the objects (in fact the IDs) on the same page,
but on different tables :) !!
I think the loop with if components could be a good idea !! But I thought
there was a way to display only one element of the list...(with an index
parameter maybe).
The help from the community is great :) I always search the mailing-list
before posting, and I have to say that it already help me a lot !!

Re: [T5] Access table values from html
Posted by Chris Lewis <ch...@bellsouth.net>.
No, 15 getters would most likely be ridiculous. What I still don't know
is will this page be displaying all 15 at once (in different tables), or
will it display only 1 based on a choice made by the user?
If one, the separate your logic for extracting the selected one from the
list, possibly in an action handler or onActivate (if the selection is
made by a PageLink and context).
If you are going to display more than one on the same page, then provide
that collection as a single List by a getter. Your template can then use
Loop (and conditional If components if needed) to display them.
Any clearer?
You are welcome for the help :-). T5 is great but still young and a bit
weak in documentation, so the community has to make up for that. I've
received much help from this list.

Re: [T5] Access table values from html
Posted by Hibowl <ju...@gmail.com>.
Ok, in fact I want all the objects from the list, but not in the same table,
that's why I dont think a Loop is usuable, because I won't display them one
after the other.
But even if I provide a getter for my object, I don't think I can tell my
page which object for the List to render (because it changes).
Now, I have instanciated all the 15 Objects of the list, and I provide 15
getters... But I don't think it's very optimal !!
Thanks a lot for your help Chris !!

Ok, but _how_ do you want to get this object? It seems like you only
want one of them from the List, so you won't need to Loop. If that's
right then you need only to provide a getter for your object (this
assumes your page knows which specific object is desired).

Re: [T5] Access table values from html
Posted by Hibowl <ju...@gmail.com>.
I'm maybe not very clear, I will try to describe better.
I have an ArrayList from Fichier, and I'd like to display their IDs.
Start.java :
private ArrayList<Fichier> _listeFichiers;
private Fichier _fichier;
//+getters/setters
Fichier.java :
private fichierId;
...
//+getters/setters
Start.html : I have several tables with Fichier descriptions, and there is a
cell where I want to display the Id of the Fichier :
<table id="tbFichiers" summary="Fichiers">
<tr>
<th id="th1" class="colonnefichiers"> # Numéro Ordre </th>
<th id="th2">
# Description
</th>
<th id="th3" class="colonneavancement">Avancement</th>
<th id="th4" class="colonnenotifications">Etat </th>
</tr>
<tr>
<td class="tdlft" headers="th1"><t:pagelink page="fichiers/detail"
context=${fichier.id} onmouseover="return overlib('Afficher détails fichier
50.');" onmouseout="return nd();"><strong>Fichier 50</strong></t:pagelink>
javascript:void(0); ? </td>
<td class="tdlft" headers="th2">alerte</td>
<td headers="th3"><strong>Fichier Id : ${fichier.id}</strong></td>
<td headers="th4"><strong>Etat </strong></td>
</tr>
.......
</table>
My problem is how to display the Id of the fichier, I would like to specify
the index in the array, so that it could render the good id.
Am I clear enough ?
thanks :)

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.

Re: [T5] Access table values from html

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.
http://www.nabble.com/T5%3A-How-to-acces-to-an-array-from-loop--tf3599642.html#a10054876
Here is an example, but how can I use it with my example ?
Thank you for your help !

Re: [T5] Access table values from html
Posted by Chris Lewis <ch...@bellsouth.net>.
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.
