FeedbackPanel messages in a Loop (Dynamic Form)
Hi,
I have a form where the number of fields are not fixed so have a Loop where
i add the fields. All these are mandatory. In a loop, your field id is keeps
the same AFAIK. So when there is a validation error the standard message
mentions the component id ..which isnt good enough in a loop, like this:
ListView horizontalSegments = new
ListView<HorizontalSegment>("horizontalSegments", hsegs) {
@Override
protected void populateItem(ListItem<HorizontalSegment> item) {
String key = item.getModelObject().getDisplayName();
item.add(new Label("name", key));
item.add(new NameableTextField<Double>("value",
new Model(getMeasurementValue(mp.getHorizontalMeasurements(),
item.getModelObject())),
Double.class,
MarshalUtils.toAlphaNumeric(item.getModelObject().name()))
.setRequired(true));
}
};
add(horizontalSegments);
When I submit the form and say 5 of them are blank. I get 5 messages saying
"Field 'value' is required."
Thats understandable because the "FeebackMessage" in the FeedbackPanel feeds
of the component ID.
While debugging I see FeedbackMessage apparently maintains some reference to
the 'Reporter'.
When I look at the code I see a ton of final methods etc, and having some
trouble modifying the method that creates the message. My reporter component
(NameableTextField) knows the correct name.
Can someone provide simple way of overriding that message
thank you.

DOH! (As Mr. Homer Simpson would say)
I forgot about ListView and reuse Items!!
hence by adding this to my loops it worked out:
@Override
public boolean getReuseItems() {
return true;
}

There seems to be another problem.
On error the form values are not retained. The same form also has some
normal fields (outside the loop). The notmal form fields that are NOT in a
loop retain their values (on re-load)
I even removed my own "NameableTextField" and am using standard & simple
"TextField" in the above code but its not retaining the values (when there
are errors).
Am debugging it but in the mean time if someone has an idea or even a "did
you try this?" please let me know.
P.S: This problem does not seem related to .setLabel(name). Its something
else and has something to do with the components being the loop.
thanks

Use NameableTextField.setLabel(model)
