You can have one component per type and also one component using them to
choose the right one to be shown at that time. That's what I'd do.

The answers you get to this is are going to be mostly personal

I would definitely create at least one component to contain all three
of the types of identifiers, then when you add a fourth, or remove
one, they magically get updated on all the pages.
Whether you create a component per identifier is really going to
probably be more about how much plumbing you need to drive each of
them. For instance, the first two seem pretty straight forward. Maybe
for the third you want to create a component to wrap any complexity
around doing cross field validation.
Maybe something like:
<t:form>
<t:accountValidation account="userAccount"/>
</t:form>
// AccountValidation.tml
<t:container>
<t:delegate to="chosenMethodBlock"/>
<t:block t:id="policyNumber">...</t:block>
<t:block t:id="creditCardNumber">...</t:block>
<t:block t:id="backAccount">...</t:block>
</t:container>
// AccountValidation.java
@Parameter
private Account account;
@Inject
private Block policyNumber;
... etc
Block getChosenMethodBlock() {
return determineBlockByAccount();
}

Good afternoon.
A few pointers on how to go about doing the following would be
apprecaited
from anyone please.
I have a page where one and ONLY ONE of the following unique identifiers
needs to appear on screen to a user, have values entered into those
fields
and have the values of the fields validated, each having differnet
validation rules.
The three types of identifier are:- (there maybe more in the future)
1. A Policy Number
2. A credit card Number
3. UK format Bank account details - this would be one field for the bank
account number and followed by 3 separate text fields to represent the
sort
code (three 2-digit textfields)
Do I create 3 separate components and include all in a page and
somethings
decides which one should be rendered on screen - again not sure how to
approach this. This is something that could be replicated on several
pages
throughout the application.
Again I'm not looking for an exact solution just a few pointers to get
me
started on how to approach this in Tapestry particularly with regards
to the
creation of new components. Thx in advance.
