Tapestry 5: @Property object is null when using in onActivate
Hi I have a situation where I have a @property object.
@Property
private Command cmd.
My onActivate would take an id and load it from db and set the obj
onActivate(Integer databaseId) {
DBRecord dbRecord = myDao.getById(databaseId);
if (dbRecord != null) {
cmd.setVal(dbRecord.getValue()); -- causes npe
}
}
How would I be able to load the db object from db and than setup the value
of Object into the command.

Re: Tapestry 5: @Property object is null when using in onActivate
Hi
Where do you initialize 'cmd' ? The variable has to be initialized
somewhere. @Property only creates public setter/getter for you, you have to
create an instance yourself.
Do something like cmd = new Command() somewhere in onActivate() before
using cmd

Hi I tried it. End up getting this. Firefox has detected that the server is redirecting the request for this address in a way that will never complete. It seems like their is a endless loop going from onActivate and object annotated with @property -- View this message in context: http://tapestry.1045711.n5.nabble.com/Tapestry-5-Property-object-is-null-when-using-in-onActivate-tp4335791p4336539.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Tapestry 5: @Property object is null when using in onActivate
Are you returning something from onActivate() method ? It will help if you share the code causing the problem. regards Taha On Sun, Apr 24, 2011 at 9:28 PM, cablepuff cablep...@gmail.com wrote: Hi I tried it. End up getting this.

[ANN] tapestry-breadcrumbs
Hi, Just wanted to mention that I just released my little bread crumb trail library tapestry-breadcrumbs over at Github (https://github.com/argoyle/tapestry-breadcrumbs). It should be available at Maven Central soonish I hope. It's not much but I hope it can be of use.

Plastic: nondeterministic PlasticManager behavior
Hi,
i'm taking a deep dive into plastic and came across a behavior i cannot explain.
If i create a ClassInstantiator from a PlasticManager that was created
with the transformers and packages in the constructor, i get the
PlasticClass in my transformer where i can e.g. assert that the class
under test has only one method. But if i instantiate a PlasticManager
with the empty constructor and call createClass() with the class under
test and the transformer, the transformer will always return an empty
list if i ask the PlasticClass for the number of methods. Can somebody
explain why?
g,
kris
public class PlasticManagerExperiment
{
private final PlasticClassTransformer transformer = new
PlasticClassTransformer()
{
@Override
public void transform(PlasticClass plasticClass)
{
assert plasticClass.getMethods().size() == 1;
}
};
@Test
public void instantiate_without_packages()
{
PlasticManager m = new PlasticManager();
m.createClass(ClassUnderTest.class, transformer);
}
@Test
public void instantiate_with_packages()
{
PlasticManager m = new
PlasticManager(Thread.currentThread().getContextClassLoader(),
new StandardDelegate(transformer),
new
HashSetString(Arrays.asList(ClassUnderTest.class.getPackage().getName(;
m.getClassInstantiator(ClassUnderTest.class.getName());
}
}

Yes, but not using autobuilding. Use a builder method instead:
public static YourService buildYourService(DependencyType1 type1, ...) {
YourService service = new ...;
service.setDependencyType1(type1);
return build;
}

Link to root
What is the best way to get the url of the root of a web application? In other words, If I'm on a page like: http://server:8080/appname/mypage?showAll=true I want to get: http://server:8080/appname I tried using: pageRenderLinkSource.createPageRenderLink(Index).toAbsoluteURI(); But that seems to retain the Request Parameters. I could use a regex to strop them off, but I'm guessing that I'm missing a better way to do it. Mark
Re: IOC Setter injection
Actually setter injection is supposed to work when autobuilding
services.

Re: Link to root
Thanks Brian and Taha. I know I can build what I need by combining both of your suggestions. I wanted to make sure there wasn't a simple way to get what I wanted without needing to build it manually, but it doesn't sound like there is another way to get this directly from Tapestry. Thanks for your help.

Event Handler Method
Hi, If I have an event link for a request. I can find the target component (with its proper class) with the ComponentSourceService. Is there a more elegant way to find the event handler method that will be invoked on the component than to search through matching method names in the component class (by reflection) and compare parameters (or check OnEvent annotations)? Background is that I want to create a new Annotation on an event handler method and need to check this when creating a special link in a custom ComponentEventLinkEncoder.
