Re: Two fundamental questions.
Always worth mentioning tapestry-model ( http://tynamo.org/tapestry-model+guide) when talking about CRUD. The more you generalize your T5 CRUD implementation, the more it will start looking like tapestry-model.

Cheng, in case you haven't seen it, here's the write-up Robert Z. provided 3 years ago listing all the cool functionality in the Tapestry5-cayenne module: http://mail-archives.apache.org/mod_mbox/tapestry-users/201112.mbox/%3cf6c2be07-ffad-4488-ae2f-2112a0e7b...@roxanemy.com%3E On Wed, Jan 21, 2015 at 6:14 PM, Robert Zeigler wrote: > I haven't tried tapestry-cayenne with 5.4.

Re: HibernateEntityValueEncoder NullPointerException - Composite/Compund Primary Key Issue
I see Lance already answered to your question on Stackoverflow. Follow his
advice and make sure you contribute the encoder. After that, you may hit
another issues with tynamo not recognizing @IdClass (see an old issue
https://jira.codehaus.org/browse/TYNAMO-168), whether it matters to you,
I'm not sure. I've used IdClasses before but not extensively, and don't
recall whether I've had them on tynamo-model or if I've simply ignored them
from it. As both Thiago and Lance mentioned, it's best to avoid composite
keys with Hibernate but I'm pretty sure you can get it to work if you need
to. I'm always happy to apply patches and please open an issue on github (
https://github.com/tynamo/tapestry-model) if you hit a specific issue with
tynamo-model (you may but you are not there yet :P ).

Re: Two fundamental questions.
I haven't tried tapestry-cayenne with 5.4. I've been heavily involved in a lot of other projects that don't involve tapestry or even java. That said, my recollection is that the Library works with 5.3, at least. At some point, I will migrate the code over to github, but that isn't likely to happen in the next month or so. Still, the library had a lot of niceties for quickly building cayenne-baked CRUD apps. I would be interested to hear whether it works as is with 5.4.

Well it looks like you need to specify the exact page name and not the
java class, example "index"
Anyhow none of it worked either, same issue as before.

Somebody's gotta be the first one. I guess many of the existing
installations are still not using the more recent versions of T5. But I
agree, it might be worth fixing so go ahead and open an issue.

Take another look at the source you pointed to yourself, but: String
canonical = resolver.canonicalizePageName(pageName);

Just seen this, is there any chance we could fix this issue so that we
don't need to write the cumbersome code below every time? I'm actually
surprised I'm the first to discover this. We send out a lot of
reminder emails etc at work via a cron job which would require this
and I also need it to work for my own project. Should I create a bug
in jira?

One last thing before we move on from this issue, what is the
canonical? Would that be the Page.class.getName() ? and I'm assuming
context is just my url context values?

My local environment uses Jetty

You are right George. Ever since the loopback reset listeners was put it in
(for T5.3), the LinkSource.createPageRenderLink(...) doesn't anymore work
outside request context (e.g. in a scheduled job). You should instead use
the linkEncoder directly (as in the implementation for
createPageRenderLink):
PageRenderRequestParameters parameters = new
PageRenderRequestParameters(canonical, new ArrayEventContext(
typeCoercer, context), loopback);
Link link = linkEncoder.createPageRenderLink(parameters);
Set loopback to false, you don't need it.

Re: PageRenderLinkSource failing in service when called by cron scheduler - Unable to delegate method invocation to property
I guess there is a bug in the PageRenderLinkSource component then or
I'm missing something because it does not seem to work. My
configuration is as followed, perhaps I'm missing something simple.
My local environment uses Jetty
In my DevelopmentModule I have the following config.
public static void
contributeApplicationDefaults(MappedConfiguration
configuration) {
// The factory default is true but during the early stages of
an application
// overriding to false is a good idea. In addition, this is
often overridden
// on the command line as -Dtapestry.production-mode=false
configuration.add(SymbolConstants.PRODUCTION_MODE, "false");
configuration.add(SymbolConstants.HOSTNAME, "localhost");
configuration.add(SymbolConstants.HOSTPORT, "8080");
configuration.add(SymbolConstants.HOSTPORT_SECURE, "8443");
}
AppModule.class
@Startup
public static void initApplication(ScheduleJobs scheduleJobs) {
scheduleJobs.startJobs();
}
ScheduleJobsImpl.class
@Inject
private PageRenderLinkSource linkSource;
public void startJobs() {
periodicExecutor.addJob(new IntervalSchedule(3000),
"Link Test", new Runnable() {
@Override
public void run() {
System.out.println("Start Link Test");
try {
Link link = linkSource.createPageRenderLink(Index.class);
System.out.println(link.toAbsoluteURI());
} catch (Exception ex) {
System.out.println("ex " + ex.getMessage());
}
}
});
}
Exception
ex Unable to delegate method invocation to property 'request' of
,
because the property is null.

Re: Two fundamental questions.
Hi Charles, We generally don't use any kind of special integration with our Tapestry+Cayenne applications here. A couple general scenarios are: 1. Your application is session-heavy (ours are). In this case you store your Cayenne objects in your session objects (page/component-based or global) and reference them from your Tapestry pages/classes/components. This can be a single Cayenne object or a List of Cayenne objects. For Lists, you use the index when the user clicks on one to select it: myListOfCayenneObjects.get(index). Typically, myListOfCayenneObjects would come from a dataContext.performQuery(). 2. Your application is session-light and you use the Cayenne ID (in the URL) to restore your Cayenne objects between requests. If security is a concern, you need to build in some additional access controls or perhaps encrypt the Cayenne ID when you generate links and decrypt on your next request. This can work well with onActivate/onPassivate, for example. If you have more Cayenne-specific questions, you can ask on the Cayenne User list, too (we are Tapestry-friendly there). mrg On Tue, Jan 20, 2015 at 4:27 PM, Cheng Zhang wrote: > Hi all, > > I am new to Tapestry.
