RE: StringResourceModel - how to pass method call instead of bean

Why dont you simple use MessageFormat's parameter substitution as desribed
in the JavaDoc, i.e.
.. new StringResourceModel(label.getTotalAlbums,this,null,new Object[] {
getTotalAlbums() });
with
label.getTotalAlbums=All Albums: ${0}
Alternatively, I you need late binding put
new AbstractReadOnlyModel() {
public Object getObject() { return getTotalAlbums(); }
}
in the object array (instead of getTotalAlbums() directly)

Wow, that is cool - excellent, excellent input - that's exactly what I

Thanks!

You got it. ('late binding' is probably the wrong synonym here, but it's
a
good metaphor anyway.
At least for me ;-) Instead of showing only the number of total albums
which
existed
at creation time of your component, by using this extra indirection step
you
get
your method evaluated each time the component is rendered (which can
happen
quite later
when your album collection changes, e.g. when you use this label on a
page
where you
manage your stuff).

RE: StringResourceModel - how to pass method call instead of bean
Well, the reason why was I didn't know that call existed ;-) Of course I
looked at the JavaDoc, but the examples there didn't show this scenario.
Thanks a LOT for your reply - this addresses exactly what I'm looking
for :-)
One more question - what do you refer to with 'late binding' - I assume
the value would be computed 'late' in the process? Please elaborate or

Didn't see a response - does anyone know how to do this?

Subject: StringResourceModel - how to pass method call instead of bean
I actually have a follow up question regarding StringResourceModel - the
tutorial shows this example, which makes sense:
add(new Label(greetings, new StringResourceModel(label.greetings,
this, new Model(user;
Now, if I want to call a method that returns a String instead, like
so...
add(new Label(greetings, new StringResourceModel(label.allAlbums,
this, new Model(getTotalAlbums(;
^^^
...with my properties file having this entry:
label.getTotalAlbums = All Albums: ${someReference}
Obviously, this doesn't work, since the new Model(xxx) call expects a
bean to be passed in. How can I do this with a simple method call? And
what would my someReference var be?
Hope this makes sense - I just want to avoid passing in/creating a bean.

Oops. That's what I meant. I had to use StringResourceModel in my
case because I had to supply parameters.

Assuming the typical tabbed panel example below - is there a good
way to
grab the tab name from the page's properties file? What I need to
do is
to internationalize the tab name. I guess I could do my own call
to grab
it from the classpath + the property file name. Was hoping
List tabs = new ArrayList();
tabs.add(new AbstractTab(new Model(first tab))
{ ^^
public Panel getPanel(String panelId)
{
return new TabPanel1(panelId);
}
});
