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 :)
