entity manager in webapp
Hi guys, is this an option to store the JPA entity manager for a wicket
webapp:
public class DBUtil {
private static EntityManagerFactory entityManagerFactory = Persistence
.createEntityManagerFactory(db);
private static ThreadLocalEntityManager emHolder = new
ThreadLocalEntityManager() {
protected EntityManager initialValue() {
return entityManagerFactory.createEntityManager();
};
};
public static User getUser(String userName) {
return emHolder.get().find(User.class, userName);
}
..
If not, thanks for possible better solutions, Juraj

FeedbackPanel inside PropertyListView
Hello,
in my FeedbackPanel, which is created inside PropertyListView I
experience this behaviour. Each item , which is created in the
PropertyListView contains a form and some data, which u can edit and a
FeedbackPanel. When there is a new message in the FeedbackPanel, it is
shown in all FeedbackPanels that are created. What do i have to do, so
that the message is shown only in the one, where it belongs?
PropertyListViewHarvestedFile propertyListView = new
PropertyListViewHarvestedFile(
allFiles, list) {
private static final long serialVersionUID =
612045960036358963L;
@Override
protected void populateItem(ListItemHarvestedFile item) {
form.add(new FeedbackPanel(feedback));
form.add(textField);
}
later, i call textField.error(False input);
thx, Juraj

PagingNavigator not working in PropertyListView
Hello, i have an component, which shows content of a table and i use PagingNavigator in this component to list the pages. This component is working correctly, when i put it directly into an page. But when i use repeater - PropertyListView , than PagingNavigator stops working correctly. No matter , which of the pages i want to navigate to, it always shows the content of the 1st page. thanks for help, Juraj __ Do You Yahoo!? Sie sind Spam leid? Yahoo!

Re: Custom IUnauthorizedComponentInstantiationListener
hi,
could u describe the proposed solution more deeply please. Idon't
know, what more i should do with my
iauthorizationstrategy , it has only 2 boolean methods and i don't see
anything, i could improve there. Btw i use RoleAuthorizationStrategy, which is
a CompoundAuthorizationStrategy.
thanks, Juraj
if you want to hide unauthorized components you should use
iauthorizationstrategy and veto component's RENDER action

Hi, i am trying to customize the behavior, when in a page a component is

application, that is subclass of AuthenticatedWebApplication i have this
init() method:
@Override
protected void init() {
super.init();
// we customize the default behavior, when there is an component in

if (component instanceof Page) {
onUnauthorizedPage((Page) component);
} else {
component.detach();
}
}
});
}
as i can see, if the unauthorized object is a page, than i call
onUnauthorizedPage((Page) component) which redirects to login page, else i
destroy the component.
What comes out as result is that the user after accessing protected page is
redirected to login page, logs in and is authentificated but than somehow
the session is destroyed and new is created for some reason which results in
loosing the authentication and login page is displayed again. So the user
actually can't log in and always ends only in the login page.
thanks for help in advance, Juraj

Visibility setting with Ajax
Hi, i have 3 panels on my page:
wicket:extend
div align=center style=background-color:red;padding:20px
h2Epubs upload/h2
form wicket:id=form
div style=background-color:#304050
span wicket:id=uploadPanel1/
span wicket:id=uploadPanel2/
span wicket:id=uploadPanel3/
a href=# wicket:id=addLinkAdd next file/a
br/
input wicket:id=submitButton type=submit value=Datei(en) laden/
/div
div wicket:id=feedback class=error style=background-color:yellow/
/form
/div
/wicket:extend
and only after clicking addLink, the user should see the uploadPanel2.
So i coded this:
add(new AjaxFallbackLink(addLink) {
private static final long serialVersionUID =
-4427831923318024979L;
@Override
public void onClick(AjaxRequestTarget target) {
uploadPanel2.setVisible(true);
}
});
When i debug, the method onClick() is really entered and
uploadPanel2.setVisible(true) is executed, but the panel is still not
visible. What else i have to do?
thanks!

Re: Visibility setting with Ajax
solved, thanks a lot
Make sure of set the OutputMarkupPlaceholderTag to true in uploadPanels also

Hi,
What it looks to me that the panel of which visibility has been set is not
added to the target.
So, IMHO *target.add(uploadPanel2)* should do.

Re: Visibility setting with Ajax
thanks, setOutputMarkupId(true) is probably not necessary., but adding
the component to target and setOutputMarkupPlaceholderTag(true) is.
Now i tried to mak eit work even better and removed the panels from the
site. i want to add them just on time, when the user request it. so site
looks now like this:
wicket:extend
div align=center style=background-color:red;padding:20px
h2Epubs upload/h2
form wicket:id=form
div style=background-color:#304050
span wicket:id=panel/
a href=# wicket:id=addLinkAdd next file/a
br/
input wicket:id=submitButton type=submit value=Datei(en) laden/
/div
div wicket:id=feedback class=error style=background-color:yellow/
/form
/div
/wicket:extend
and i try to create the panel dynamically:
public void onClick(AjaxRequestTarget target) {
panel.setOutputMarkupPlaceholderTag(true);
target.addComponent(panel);
panel.add(new UploadFilePanel(filePanel));
the markup of UploadFilePanel:
wicket:panel
table style=padding-bottom:5px
tr
td width=180pxTyp/td
tdselect wicket:id=type //td
tdTitel/td
tdinput type=text wicket:id=title //td
/tr
tr
tdJahr/td
tdinput type=text wicket:id=year //td
tdAusgabe Nummer/td
tdinput type=text wicket:id=issueNumber //td
/tr
tr
tdDatei/td
tdinput wicket:id=fileUploadField type=file //td
td colspan=2 valign=bottomIch bin Inhaber
des Mediensinput type=checkbox wicket:id=ownerCheckbox//td
/tr
/table
/wicket:panel
this all end in the error:
WicketMessage: The component(s) below failed to render. A common problem
is that you have added a component in code but forgot to reference it in
the markup (thus the component will never be rendered).
1. [MarkupContainer [Component id = panelX]]
2. [MarkupContainer [Component id = type]]
3. [MarkupContainer [Component id = title]]
4. [MarkupContainer [Component id = year]]
5. [MarkupContainer [Component id = issueNumber]]
6. [MarkupContainer [Component id = fileUploadField]]
7. [MarkupContainer [Component id = ownerCheckbox]]
i understand that i didnt declare the things in the markup, but thats
what i want (create them not at the start, but never or later, when the
user clicks on the link). So what is needed to create the
UploadFilePanel dynamically?
thanks for help
1-Put
uploadPanel2.setOutputMarkupId(true);
uploadPanel2.setOutputMarkupPlaceholderTag(true);
uploadPanel2.setVisible(false);
when you create the panel.
2- on
public void onClick(AjaxRequestTarget target) {
uploadPanel2.setVisible(true);
target.addComponent(uploadPanel2);
}
