I am thinking of using lazy initialization of collections in thier getters:
example:
private java.util.Set myEntities;
|
|public java.util.Set getMyEntities() {
| if (myEntities == null) {
| myEntities = new HashSet();
| }
| return myEntities;

when I use the same embedded component several times in my entity (e.g.
Addresses), I need to use @AttributeOverride for EACH field of the embedded
component.
This is tedious when the entity is used several times and has a lot of fields.
And if you add a field to the embeddable component, you mi
AFAIK all your fancy annotation stuff is useless when you explicitly code your
query.
if you would just use em.find(Person.class, Id) your annotation setting should
work
but if you hardcode your query, you must explicitly use a fetch statement like:
from Person p inner join fetch p.metadata
V
Usually you don't want to just truncate data.
I'd recommend to use @Length(max=100) (then you don't need length=100 in the
@Column annotation) - this way you could easily validate the input data.

I want the user to select a timezone and then display a the server systemdate
in the users timezone...
switching the timezone seems to work, but the page will always display the same
date, no matter, which timezone I select.

hi,
I also searched 4 smth. like TimeZone.timeZones (much like Theme.themes)
I found a bugreport, saying this was fixed in version 1.1.0:
http://jira.jboss.org/jira/browse/JBSEAM-405
however, can it be, that this is still missing?
however, it seems not to exist in seam version 2.0.0.GA:
http://d
what I'd like to for input fields:
* user opens page: show no image after the input field
| * invalid input: show a red sign
| * valid input: show a green sign
how would I do that?
details:
when using s:decorate you can use the vars invalid and required inside of the
template
but how I can
for more details on this please see:

well, I asked it on a JSF forum - no reply
however, I wrote a simple sample application with JSF on JBoss without SEAM and
it worked as expected (but I used jsp instead of facelets)
anyway
I just debugged into the SEAM source and found out, that the problem is, that
the messages component (org.

well, after some other checks, it turned out, that the message string is not
read corectly from the .properties file
string in .properties file:
mtr.test.param.format=string {1} currency {0,number,#.#} integer
{2,number,integer} date {3,date,short}.
when I output the message string in the HTML
I forgot to post the explanation, why the original code does not work:
facesMessages.add("#{messages['registration.success']}", "#{webUser.name}");
When debugging into the seam source I learned, that this cannot work, because
the Interpolator.interpolate() method wil:
examine the given string and
short explanation:
the registration.success string in the resource bundle is:
registration.success={0} has been registered sucessfully
in my java file, I just want to add a faces massage like this:
facesMessages.add("#{messages['registration.success']}", "#{webUser.name}");
but this will render
ok - I just found out why this does not work
when you use the @Stateless or @Stateful annotation:
* the class must implement a method with the @Remove annotation.
from the seam reference manual:
anonymous wrote : In addition, stateful session bean components must define a
method with no parameter
hi,
for test reasons, I have created a very simple class, that only returns some
simple values (see below for details). However, since the class does not need
to keep any state, I think I should add the @Stateless annotation. But this
does not work - without the @Stateless annotation it works f
