Why don't you use onPrepareFromQuantity(Integer quantity) instead? Does
this validation require other fields to be checked?

The following code illustrates what I am doing:

<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.

Hi,
Hi!
I have a loop inside a form that renders a textfield and some other
controls. When I am doing cross field validations in the ValidateForm
event while iterating over a collection (the source of the loop), I
would
like to record error messages against the form with the field in error
to
get the
normal error highlighting. How can I get to the field in this case
since I
can't use normal injection?
Why not? Even when inside a loop, you don't have more than one instance
of
a given component. Example:
<t:loop ...>
<t:textfield t:id="title".../>
</t:loop>
You have only one instance of the TextField with t:id "title",
regardless
of the number of iterations.
I don't know if this solves your problem, but at least I'm trying to
help
you figure it out. ;)
