Re: loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
err... i mean...
mypanel extends panel {
mypanel(id, Person person) {
setModel(new Model(new Person()))
}
but u get the drift ;)

Re: loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
Sure I can appreciate that :) However I define my panels to accept certain
objects to chuck into the model, so thats fine.
It means I can provide translations for pojos from non wicket jars using a
method similar to wickets nice 1 class, 1 property file approach.
Eg,
mypanel extends panel {
mypanel(id, Person person) {
setModel(new Person())
}
}
MyNonWicketProject.jar
Person.class
Person.properties
entity=Person
name=Name
surname=Surname
Great for generating forms, and combined with generics becomes quite
powerful.
My usecase and requirement of wicket is probably non typical (which is why
wicket rocks because I can customise it) - I have a large team each
developing different modules, and things like translations need to be
available in non wicket environments. Everything is translatable.
Still - would be nice if the
MarkupInheritanceResolver$TransparentWebMarkupContainer somehow indicated it
was the the page (and returned the pages model).
I can live without it.

hm. dont know if doing localization based on type of model object is a
great idea. there are many usecases where model type is quiet
aribitrary, and as you have found out yourself you dont know what
component you get passed in, so you just need to handle it in a way
that makes sense to you.

Re: loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
I'm writing my own
It does this
@Override
public String loadStringResource(Component component, String key) {
if (component == null) {
return null;
}
String result = null;
Locale locale = component.getLocale();
String style = component.getStyle();
IModel model = component.getInnermostModel();
if (model != null) {
Object object = model.getObject();
if (object != null) {
result = loadStringResource(object.getClass(), key, locale,
style);
}
}
return result;
}
Basically if does the translation lookup based on whatever object is set to
the model of the component.
It works fantastically except when the keys are in - because component becomes an instance of
MarkupInheritanceResolver$TransparentWebMarkupContainer and getModel returns
null.
Are there other circumstances where the component can be
MarkupInheritanceResolver$TransparentWebMarkupContainer and it not be a
page?

Re: loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
Do you know an elegant solution Igor?
Detecting when the component IS a page - when something like is used in a page's markup, the component sent to the
StringResourceLoader is
MarkupInheritanceResolver$TransparentWebMarkupContainer and not Page.
If the strings are resolved in java (ie, getString("foobar")) (according to
michael)
component instanceof Page == true
if the strings are resolved in markup (ie, )
component instanceof Page == false

Re: loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
I did an elegantish... workaround. - the page instantiates a panel - the panel has the model. Basically my pages defer almost everything to panels - and I guess it also aids in their reuse/embeddability. I'm quite familiar with instanceof thanks ;) Michael Sparer wrote: > > well one (as said ugly ;-)) way that comes to my mind is to ask if > component.getParent().getParent() instanceof Page (that should also work > if you use nested subpages). > > regards, > Michael > -- View this message in context: http://www.nabble.com/loadStringResource%28Component-component%2C-String-key%29---correct-method-to-check-if-the-component-IS-a-Page--tp16930303p16957861.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
well one (as said ugly ;-)) way that comes to my mind is to ask if component.getParent().getParent() instanceof Page (that should also work if you use nested subpages). regards, Michael you could check if it's a transparentwebmarkupcontainer with instanceof.

Re: loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
I basically want the components Model. It's legitimate for it to be null. So, if I can see which component is a page, then i can easily call the "getPage().getModel()" Of course if it's TransparentWebMarkupContainer then getModel returns null even if the page has a model set. It appears to work with panels, just not page. Are there other conditions that will cause the component to come through as TransparentWebMarkupContainer? How can I determine it's a page :). Ugly hacks are not something i enjoy/advocate using. On Tue, Apr 29, 2008 at 6:56 PM, Michael Sparer <[EMAIL PROTECTED]> wrote: > > yepp, then the TransparentWebMarkupContainer gets passed in.

Re: loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
yepp, then the TransparentWebMarkupContainer gets passed in. And you're
right, it's gonna be a filthy hack if you try to find out if its a Page.
Unfortunately I've got no further suggestions but it'd be interesting to
know why you want to distinguish between pages and other components anyway

Thanks for your reply,
Maybe it's because I am using a in the
markup?!
There isn't really any code to show. I put the wicket:message into the
page, then i check the params coming in to the method.
I'll have a bit more of a play I think, but I would be interested in what
your results are with the

I just subclassed ComponentStringResourceLoader and tried calling

instanceof Page returns true. Maybe it'd be helpful to see some code (and
your usecase 'cause maybe there's another way to do it).

loadStringResource(Component component, String key) - correct method to check if the component IS a Page?
Hi, I've written my own class that extends ComponentStringResourceLoader (i might change it to extend some other class) At any rate, when loadStringResource(Component component, String key) is called, and the component is a panel I can call "getModel" and retrieve the model. When the component is a Page, it comes in as MarkupInheritanceResolver$TransparentWebMarkupContainer - and getModel returns null (even if the page has had the model set). So... how do I determine is the component is a page? - what is the condition I should check? -- View this message in context: http://www.nabble.com/loadStringResource%28Component-component%2C-String-key%29---correct-method-to-check-if-the-component-IS-a-Page--tp16930303p16930303.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
