I have been so busy this month and I have a ton of stuff to post here,
but time...time is my problem :-)
I am almost finished with the new website/blog design and soon you will
see how things are going to change, but I don't want to spoil the surprise,
so I am not going to say more.
So, what else is new you would ask?
Well, I made a 1st communion cake as a gift this week. It was for Julia,
the daughter of a very good friend of mine . You probably remember that I
made one 1st communion cake last year as well. It was for Julia's older sister-
Carina.
I had a hard time deciding what should I do for Julia's cake.
At first I had an idea about lace gloves, but then I started thinking about
handkerchief..and I asked my friend if she has one as a keepsake from her mom
( Julia's grandmother). It turns out she had one!It was just perfect!!!
Then I started thinking about the flowers, my friend's name is Rose, so I
figured roses would be appropriate, and the girl's favorite color is
light-purple-violetish, so it was decided.
But, there was one small problem-I have never made gum paste or gum paste
flowers in my life, so I had to prepare at least a week in advance to make
sure everything will go smooth.
And I started with the gum paste recipe of Scott Clark Woolley.
Then I remembered I had seen a very beautiful cake that Louise from Cakejournal.com
made and she shared some tips on how to make gum paste roses.
She had posted a link to the tutorial on how to make gum paste roses
of a very talented cake designer Fran McGregor. The link is in the 23rd
post after the picture and you'll have to download it.
As I mentioned in the previous post, I have made a 1st communion
cake for a friend of mine's daughter.
The cake was with 5 chocolate layers and caramel-coconut cream.
I've brushed the layers with caramel-brandy sauce and I have to tell
you the taste was unbelievable! The cake was so moist and creamy and
the candied walnuts gave it a little bit of crunch. Very interesting combination, I'll definitely make it again.
Only the candle is real, everything else is edible.
The flowers are completely edible ( except the flower wire) too,
the handkerchief is a replica of one that the girl's grandmother left for her.

One of the major upsides of using Tapestry 5 is the much touted live class and template reloading. Up until recently, if you followed my previous post on working with Tapestry 5 and NetBeans, you probably ended w/ a workable solution, but still not ideal , as the live template and class reloading wasn't exactly working as expected. As a result, whenever you wanted to see the changes that you made in the live app (after running mvn jetty:run) you had to do the following:
mvn compile resources:resources

[INFO] Total time: 18 seconds

[INFO] Final Memory: 16M/71M
The issue here was that NetBeans (in 6.1 and prior) did not support CopyOnSave or CompileOnSave properly in Maven projects (it did for NetBeans native projects, so if you had set up a NetBeans native project w/ explicit jar dependencies, etc it would work fine). The effect of running the above command was to compile your changes, and copy the compiled classes and modified resources into your <outputDirectory> (typically target/classes) . So, the 18 seconds above are not exactly something to lose sleep over, but it's still not the same like having the immediate Grails(or Rails)-like immediate feedback loop (that is, "Ctrl-S->Alt-Tab to browser->F5", which is "Save->Switch to Browser->Refresh").
In any case, help is on the way.
In the most recent version of NetBeans (in the 6.7 daily builds ), the issues w/ CopyOnSave support has been fixed (well, almost fixed, see the NetBeans IssuZilla issue), and now it transparently copies your modified resource files to target/[app-name]/WEB-INF/classes. Thus, with just a minor tweak, you can accomplish a Tapestry 5 Nirvana.
<outputDirectory>${project.build.directory}/${project.build.finalName}/WEB-INF/classes</outputDirectory>
Now, this is a bit of a hack. Basically, we're telling maven to use the target/[app-name]/WEB-INF/classes to do the initial and any subsequent builds, which is where both the classes from src/main (and whereever else) and src/main/resources end up. The trick here is that this is the same directory that "mvn package" uses, and it is also the same directory that NetBeans uses for the Compile-on-save functionality. Basically, when you make changes to your page template sin src/main/resources (and after you've run your app in Tomcat once), NetBeans continues to compile the classes and copy the modified resources from src/main/resources and drop them into the target/[app-name]/WEB-INF/classes.
Considering that this is indeed a a hack, I filed a patch for NetBeans to properly support this T5 setup in Maven project. However, what got into 6.7 is only the fix to properly copy resources into target/[app-name]/WEB-INF/classes (and not in target/classes). The develoeper on the issue has some other ideas on how this should go, hopefully the full fix will go into the NetBeans version after 6.7. In the meantime, either use this little hack, or I'll probably try to repackage my fix as a standalone plugin to support this out of the box.
