The following code illustrates what I am doing:
<t:form t:id="form" ...>
<t:loop source="items" value="item" ...>
<t:textfield t:id="quantity" value="item.quantity" .../>
</t:loop>
</t:form>
@InjectComponent private Form form;
@InjectComponent private TextField quantity;
@Property private Item item;
void onValidateForm() {
for (Item i: getItems()) {
if (...cross-field check...) {
form.recordError( quantity, "Error message");
}
}
}
What I find is that when I get to onValidateForm(), the injected quantity
field is always the last instance (the one bound to the last item). I need a
way to get the instance that matches the current item in the for loop.
Hope that clarifies my question. Thanks.
