Hi Francesco,

I can't modify it..
This is the code: (inside a form)
<wo:form>
<fieldset>
<wo:if condition = "$isTableLuogo">
<wo:loop list = "$ipnDisplayGroup.displayedObjects" item =
"$aLuogo">
<p><wo:textfield value = "$aLuogo.nome"></wo:textfield></p>
</wo:loop>
</wo:if>
<p><wo:link action="$addItem"> aggiungiElemento</wo:link></p>
<p> <wo:link action = "$applyChanges">Applica</wo:link>
<wo:link action = "$cancelChanges">Annulla</wo:link>
<wo:link action = "$saveChanges">Salva</wo:link></p>
</fieldset>
</wo:form>
If I try to edit the field, and press "Apply" the record is not
updated...
What is wrong?
(This is the code for applyChanges)
public WOActionResults applyChanges() {
session().defaultEditingContext().saveChanges();
return null;
}
First let me note that using the defaultEditingContext for modifying
and saving objects is A Bad Thing™. Looking at your page code it
should work but... the problems that could cause your page not
function as you expect are:
1. when you submit the changes is it possible that your condition
isTableLuogo changes during the takeValuesFromRequest phase?
2. what is the editingContext of your ipnDisplayGroup? If it is not
using the default editing context of course you wont do anything by
calling saveChanges on the defaultEditingContext.
Another little tip you should return context().page() instead of null.
What is the difference of your applyChanges() and saveChanges()?
