Historical errata for Domain-Driven Design Using Naked Objects

Remove the word ‘out’ from 2nd graph: “we work to identify out the key concepts…”

Going to localhost port 8080 to use the HTML viewer as instructed on this page gave me a “403 Forbidden” error.

Instead, the correct link needs to end with “logon.app” as stated in the server console log on start-up.

Unlike your screen shot, File -> New -> Project -> Maven did not generate any source folders in Eclipse, only “plain” nesting folders. Hence my project explorer looks like project > dom > src > main > java > com > mypkg > nofapp > dom > claim > Approver.java, not project > src/main/java > com.mypkg.nofapp.dom.claim > Approver.java, which would have been much preferable.

Please ignore my erratum #39675 - I was in the parent project, not the -dom suffixed project when I was seeing the nested resource-style packages as opposed to the Java source packages.

Last sentence before section “Installing Naked Objects Templates” says “..then we’ll can get onto the coding itself.”

Where you say “..editing the nakedobjects.services key in the nakedobjects.properties file (in the client project)…” did you mean the “-commandline” project? My workspace doesn’t contain a client project.

Also, the directions here don’t mention to clear out the cruft to do with the expenses application from the properties file if you started off as instructed earlier in the chapter.

Para 2: “What we’re need to do is identify icons and copy them…”

I’m not sure if I should be raising this elsewhere, but the nosffil and nosufil templates (the first of which is useful for the repository additions on this page) specify an incorrect return type of List rather than Type on their respective “match” methods.

The first sentence on this page is odd, since there was no mention of getContainer() in the sample on the previous page, and in that sample it was not necessary to call getContainer() in order to call persist(), since persist was already available on AbstractContainedObject, which is a superclass of Customer. Did I miss something?

This code fragment is different than the one generated by a template - a call to a setter is missing :

// associate new
setOwningCustomer(owningCustomer);

public void modifyOwningCustomer( final Customer owningCustomer) {
// check for no-op
if (owningCustomer == null ||
owningCustomer.equals(getOwningCustomer())) {
return;
}
// delegate to parent to associate
owningCustomer.addToCars(this);
// additional business logic
onModifyOwningCustomer(owningCustomer);
}

I guess, the text below should be:
Update the Title class by ADDING a Name property…
instead of:
Update the Title class by ADD IN a Name property …

I believe it must be:
if you HAVEN’T BEEN CODING along …

instead of:

If you HAVEN’T WEREN’T CODING along then load up this chapter’s version

public void validateAddToCars -> public String validateAddToCars

Ditto for remove.

Customer-Name.java
public class Car … should be public class Customer …

Last sentence on page seems to be a ‘composite’ of two - first should state something like “…by pressing the Shift key at the same time as clicking on the icon, you can see the menu options shown in fig 4.3. If you do [whatever] using the HTML viewer, it …”

references FredSmithSessionFixture instead of LogonAsFredSmithFixture (not that I can get it to work anyway!)

Just submitted an erratum relating to the Coffee Bytes link given on this page being broken, then was surprised not to see it in the list of errata.

Then I saw the message that errata containing hyperlinks are not accepted! I’ll try again, leaving the protocol part off the URLs.

The link you gave for Coffee Bytes was to www.realjenius.com/platform_support

This is broken, but this works: archive.realjenius.com/platform_support

The latter link is referenced from the project page at code.google.com/p/coffee-bytes/
(which mentions that this project is no longer being maintained)

Unless I am misunderstanding (hand coding in Netbeans 6.8)
book shows nakedobjects.properties as

nakedobjects.services.prefix = com.pragprog.dhnako.carserv.dom

should read

nakedobjects.services.prefix = com.pragprog.dhnako.carserv.service

At least, that what I needed to do to get it running

Cannot get “fsmith” to login, the logged in user is still “exploration” when I run it in exploration. The same problem persists even when I import chapter04-02 into eclipse from the given source code, except that in this case, the user “sven” is logged in. Long story short, I cannot log in as “sfmith” using the LogonAsFredSmithFixture method. It seams this error is very similar to error #42002.

In the Exercises section, the sentence “Finally, we
could simplify the AbstractCustomerFixture’s newCar( ) method to use Customer’s
newCar( ) action instead.” should be “Finally, we
could simplify the AbstractCarFixture’s createCar( ) method to use Customer’s
newCar( ) action instead.”

In the createCar method, two lines (Car car = newTransientInstance(Car.class); car.modifyOwningCustomer(customer);) should be replaced with only one line (Car car = customer.newCar();).

The GivenCustomerWithNoVehiclesTest class has a typo: the line assertThat(customer.disableDeleteVehicle(), is(nullValue())); should be assertThat(customer.disableDeleteVehicle(), is(not(nullValue())));
