Hey Geoff...
I didn't quite understand the code below but after much cranial banging,
I've figured out how to do it. Since I'm new at Tapestry, I'll post the
solution tomorrow for everyone to look at (in case I'm doing something very
unTapestry-like/BadTM...).
BTW, I'll post the solution tomorrow because its late, I've been at this for
hours and my head feels like its about to explode; I think I'll call it a
day.
Cheers...

Davide,
For this problem I only have code that worked in T3 using the
ListEdit component. In T4 you should use the For component. I hope
the clue you're looking for will be in here nonetheless...
<tr jwcid="@ListEdit" source="ognl:picksModel.keys
"
value="ognl:picksModel.key" listener="ognl:listeners.synchronizePick"
element="tr">
<td>
<span jwcid="@PropertySelection"
model="ognl:pickSelectionModel"
value="ognl:pick.pick">PickSelector</span>
</td>
</tr>
The java...
public abstract ListEditMap getPicksModel();
public abstract void setPicksModel(ListEditMap value);
public abstract void setPick(SinglePick value);
private PickSelectionModel pickSelectionModel;
public PickSelectionModel getPickSelectionModel() {
if (pickSelectionModel == null) {
pickSelectionModel = new PickSelectionModel();
}
return pickSelectionModel;
}
public void synchronizePick(IRequestCycle cycle) {
ListEditMap map = getPicksModel();
SinglePick sp = (SinglePick) map.getValue();
if (sp == null) {
setErrorMessage("out-of-date");
throw new PageRedirectException(this);
}
setPick(sp);
}
public void accept(IRequestCycle cycle) throws ValidationException
{
Visit v = (Visit) getVisit();
try {
// Get all the picks from the screen
ListEditMap map = getPicksModel();
List picks = map.getAllValues();
// iterate through the list, call back end, catch
exceptions, etc...
}
}
The Property Selection...
public class PickSelectionModel implements IPropertySelectionModel
{
// etc...
HTH,
Geoff Callender
