Consider this example:
In my html template:
.
<table>
.
<tr jwcid="@Foreach" element="tr" source="ognl:myList"
value="ognl:listItem">
<td> . </td>
<td><input type="submit" jwcid="@Submit"
listener="listener:removeItem" label="message:remove"/></td>
</tr>
</table>
.
In my java class I have a listener:
public void removeItem() {
getMyList().remove (getlistItem());
}
So, to put it in English, I have a Foreach loop with a listener inside it
that is supposed to remove an item from the list being displayed.
Whenever I click one of the "remove" buttons my removeItem() method is
called as it should, except that the item returned by "getListItem()" is
always the last item in the list. It's never the item corresponding to the
removed button I clicked, so I always end up removing the last item, no
matter which button I click on.
When I use "For" instead of "Foreach" not only does the "getListItem()"
contain the last item in the list, but the list is intact when the page is
reloaded (no items removed).
To me this seems very strange since there is no other way of knowing which
of the buttons was clicked. I don't know if I'm doing something wrong or if
it's a bug. I understand that doing this was an issue in Tapestry 3 due to
limitations during the rewind cycle and I had to use some special logic to
do it. I thought in Tapestry 4 I could use this more direct approach but
maybe I'm still missing something.
I'm using Tapestry4-beta5 but I tried it with beta4 and got the same
problem.
Any ideas?
