move your DAO into another package, yourApp.entities or sth..

Re: how to use ioc of t5 ?
In my setup i've got all my hibernated classes in the 'entities'
package - which is automatically picked up tapestry-hibernate - so
i've not had to make a contribution like this. I'm afraid i don't
have time to play with it right now either..., sorry.
As an experiment, you might try moving (some of) your hibernated
classes from 'domain' into 'entities' and commenting out the
contribution code, just so we know whether your exception is related
to contributing a package or something else.
Also, is there more to that exception stack? It doesn't seem to
mention a cause...
Lastly, i have a vague recollection of a past thread in this list
about contributing packages to tapestry-hibernate... did you happen
to
run across anything in the archives?
Cheers,
lasitha.

Company.java is in com/myspacce/domain:

public class Company {
@Id
@GeneratedValue
private int id;
private String name;
public Company()

public String getName()

I have the tapestry-hibernate module in my classpath.
error is :

There are a couple of starters you should checkout:

Re: T5: Tapestry, Hibernate and Underscores.
Hi Olivier, In that tutorial the only place with underscore is _session, the entities for hibernate do not have underscore, I prefer this way, it looks normal when u do some sql/hql queries, but for Tapestry variables ,seems to me, a unspoken rule here is to prefix underscore.

Re: [T5] Label
Hi Michael.
In the future it should be easy to do this with a Mixin, but there are
a couple of problems that might (or might not) get in the way currently.
Anyway, it's very easy to write components. Just take the Radio.java
source eg from http://svn.apache.org/viewvc/tapestry/tapestry5/trunk/
tapestry-core/src/main/java/org/apache/tapestry/corelib/components
and hack away till it does what you want. In this case, change:
@BeforeRenderBody
boolean renderBody()
{
// Don't render the body of the component even if there is one.
return false;
}
to return true based on the criteria you want, and the opposite here:
@AfterRender
void after(MarkupWriter writer)
{
writer.write(_field.getLabel());
writer.end(); // label
}
To see how to write your own components and where to put things see:
http://wiki.apache.org/tapestry/Tapestry5HowTos
Note that if you are using T5.0.6 then a few things have changed like
templates are now named *.tml. Search the list for other changes.
Cheers,
Nick.

Re: [T5] RadioGroup
The obvious answer to your question is the source for RadioGroup.java. ;-) http://tapestry.apache.org/tapestry5/apidocs/src-html/org/apache/tapestry/corelib/components/RadioGroup.html Basically, RadioGroup is responsible for the collective behaviour of Radios when each is rendering, and when the form is submitted, through RadioContainer Environmentals stored in the Environment service: http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/RadioContainer.html http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/services/Environment.html When you understand how this class behaves, you could consider moving the functionality into either a new Radio component or possibly into a new Form component - though Form is quite complex already. Yet another approach, since you are already preprocessing the html, would be to automatically insert RadioGroups where necessary. If you come up with an interesting solution, please let the list know. Cheers, Nick. Michael Gerzabek wrote: Hi, I'm new to tapestry and started with T5. It's awesome stuff! With the tutorial, the maven archetype and a few hints from the wiki and the mailing list startup was straight forward. Compared to many other frameworks this is really one of the BIGGEST advantages of T5. Great job guys!!! I'm working on a small technology spike to get new directions in developing webapps in future. It is important for me to have a clear separation between the different roles in projects. One role is the graphic designers. They have to provide the whole xhtml stuff. Our customer likes to have the fancy features also in their logic pages. So we try to give them what they want making our lives easier. On the other side there ist the role of the web developers. They need to put those inanimate pages into exist and gather the user conversations. The T5 programming model does a brilliant job here. I love Howard's quote ... pages are facilitators ... from one of the screencasts. The last role of course is the one of the backend people. So what we primarily do is we take those inanimate xhtml pages and guide them through an xsl stylesheet transformation to prepare tapestry markup. It work's really nice. T5 does a very nice separation of concerns out of the box here. At the time there's only one small bump when it comes from using those pages the designer gives us to .tml. And it's the use of radiobuttons. People are used to group different radiobuttons simply by giving them the same name. T5 requires the newly introduced tag t:RadioGroup to group radiobuttons that belong together. So my question is, where do I have to look to get an idea of how to implement my own t:Radio tag that automagically creates a new t:RadioGroup for each occurence of a new groupname?

Re: [T5] Label
Hi Nick,
That was REALLY easy! Wow, 5 minutes and a new component is born. It's
hard to believe. The more I work with T5 the more I like it.
So let's have a look at RadioGroup...
Cheers,
Michael
