Re: How to externalize web page elements to make it configurable?
Column names (at least with DefaultDataTable) are supplied via an IModel in the constructor of AbstractColumn, so you can supply whatever you want. Those values can come from a database, properties files, etc. You can use a ResourceModel to load the values from your page/component's properties file.

How to externalize web page elements to make it configurable?
I am looking for some design patterns or best practices for configuring web page fields. My web page has a table, which is dynamically created by my API (Wicket). Currently all the column names are hard coded in the java but I want to make it externalizable that way I can add/remove/modify fields without modifying java code. Also I want to define each field type, valid value ranges etc.. in this external file. Are there any recommended approaches for this requirement? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-externalize-web-page-elements-to-make-it-configurable-tp2997775p2997775.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: How to add image to table column and how to change image this on click?
Yes this worked! Thank you very much. I have another question, If I want to make the complete column header as clickable, how do I do that. That is, currently it supports only clicking on column name, but I want to have option to click anywhere on that table column header for sorting. Is it possible? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-add-image-to-table-column-and-how-to-change-image-this-on-click-tp2996263p2997566.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

The session is always going to be created for every request (stateless or
not). But, if the session wasn't bound during the request, it is temporary
and thrown away at the end of the request.

When running as a webapp, the web app is created from your web.xml configuration when the container starts and Wicket puts the Application into a ThreadLocal at the beginning of each request. You need to do something to set up the application yourself if you're running this outside of the container. If this is your goal, see the examples for running WicketTester - they show how to set up your application outside the container. -- Jeremy Thomerson http://www.wickettraining.com

Try adding setStatelessHint( true ) in the HomePage constructor.
public class HomePage extends WebPage {
public HomePage() {
add(new Label("label", new Model("Hello, World")));
setStatelessHint( true ); // <- new
}
}

Backbutton support
Does anyone have any resources on BackButton support with Wicket? My application, although complex, is all one WebPage, it uses Ajax to switch panels dynamically. What would be the best way to handle the back button in this case?

Re: FeedbackPanel for each ListItem in ListView
Hi, try:
yourListView.setReuseItems(true);
>From the JavaDoc:
*WARNING:* though you can nest ListViews within Forms, you HAVE to set the
setReuseItems property to true in order to have validation work properly. By
default, setReuseItems is false, which has the effect that ListView replaces
all child components by new instances. The idea behind this is that you
always render the fresh data, and as people usually use ListViews for
displaying read-only lists (at least, that's what we think), this is good
default behavior.
However, as the components are replaced before the rendering starts, the
search for specific messages for these components fails as they are replaced
with other instances. Another problem is that 'wrong' user input is kept as
(temporary) instance data of the components. As these components are
replaced by new ones, your user will never see the wrong data when
setReuseItems is false.

FeedbackPanel for each ListItem in ListView
Hey!
I have ListView and every ListItem has multiple AjaxEditableLabels and
one FeedbackPanel added to it. Each FeedbackPanel should only show
messages that were reported within the same listitem.
I tried the following but it didn't work:
protected void populateItem(final ListItem item) {
[...]
item.add(new FeedbackPanel("someId", new
ContainerFeedbackMessageFilter(item)));
}
Somehow when the AjaxEditablelabel submits, the list items get created
from scratch, which screws up object references and therefore
container.contains(message.getReporter(), true) of the
ContainerFeedbackMessageFilter never returns true.
Am I doing something wrong here? What would be the proper way to check
if a feedback message was created within a listitem?
Cheers,
Patrick

Re-Rendering Table after submitting results in error
Hello,
I've just come across wicket and started playing around - so far, I encounterd
some issues:
My first issue is:
Given a table and a Panel:
//SomePage.java
private TablePanel tp;
tp = new TablePanel("tablePanel",columns,new
PersonBeanProvider(searchFilter),12);
//TablePanel.java
class TablePanel extends Panel{
public TablePanel(String id, final List> columns,
PersonBeanProvider personBeanProvider, int rowsPerPage) {
super(id);
AjaxFallbackDefaultDataTable table = new
AjaxFallbackDefaultDataTable("table", columns,personBeanProvider,
12);
add(table);
}
}
And the html:
SomePage.html
(...)
TablePanel.html:
[table]
Everything is fine. But: If I introduce a form for modifying "searchFilter" (a
String to be passed) in this way:
searchField.add(new AjaxFormComponentUpdatingBehavior("onChange"){
@Override
protected void onUpdate(AjaxRequestTarget target) {
tp = new TablePanel("tablePanel",columns,new
PersonBeanProvider(searchFilter),12);
tp.setOutputMarkupId(true);
target.addComponent(tp);
}
});
I get an error _after_ submitting the form - what may be wrong here?
Thanks,
Keep smiling
