Re: Best practice for custom page renderer
Doing more investigations I found that the problem is gathering the
extended browser info. Omitting that, BrowserInfoPage is stateless.
Sorry for the noise.

Yes, I am sure.
The problem could be that I'm using ClientInfo to collect info about
clients for analytics purposes. It uses BrowserInfoPage that is
stateful. For that reason I checked it in isOnePassRender() method.
Is there a way to convert BrowserInfoPage to stateless?
For example every page I create has a form to submit a search but I
used a StatelessForm for that, therefore if a page does not contain any
other stateful components or behaviors, it is stateless.

Best practice for custom page renderer
Hello,
I didn't find any useful information about that in the documentation.
For some reasons (e.g. search engine bots or clients unable to follow
redirects) on some pages I would like to have an http 200 response. By
default Wicket uses REDIRECT_TO_BUFFER render strategy that send a 302
redirect first.
Which is the best practice for use ONE_PASS_RENDER strategy?
Is it reasonable to adopt ONE_PASS_RENDER for all stateless pages or is
it better to change the render strategy only for specific pages?
Is setPageRendererProvider() the good place where to handle that?
For example:
setPageRendererProvider( new IPageRendererProvider() {
@Override
public PageRenderer apply(RenderPageRequestHandler handler) {
return new WebPageRenderer(handler) {
@Override
protected boolean isOnePassRender() {
IRequestablePage page =
getRenderPageRequestHandler().getPage();
return page.isPageStateless() ||
page instanceof BrowserInfoPage || super.isOnePassRender();
}
};
}
});
I' working with wicket version 8.3.0.
Best regards
Alberto

Yes, but it doesn't work with lists. I have to add items manually,
isn't it?

PropertyListView without inner component
Hello,
I have a PropertyListView in a page with a CompoundPropertyModel on a
JAXB generated class.
I have simply to repeat a "" element.
I found two solutions:
- using an outer element;
- using an inner element with
setRenderBodyOnly(true).
ex.
queue(new PropertyListView("titles.title") {
@Override
protected void populateItem(ListItem item) {
item.queue(new Label("value"));
}
});
"value" is the property of the model but I would not have an inner tag
with that wicket:id.
Is it possible?
Regards
Alberto

Custom http error pages
Hi, I'm using the latest version of wicket. I'm trying to write custom pages for http errors. The standard way, using web.xml, is not useful for me because I would print custom messages too. I tried to write a RequestCycleListener extending AbstractRequestCycleListener class, but it seems that AbortWithHttpErrorCodeException exceptions do not trigger onException method of the listener or they have been already consumed. Which are the best way to do that? Best regards. Alberto - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
onInitialize() and exception handling
Hi, I have a wicket application where I create page components (mainly labels and ListViews) using onInitialize() method of some panels I have in every page. In some cases, during the creation of the components, some exceptions can occur (for example if the content is downloaded from a webservice that returns error 404), and I would propagate it, but onInitialize() of Panel does not throw exceptions. So my questions are: which are the best practices to deal that cases? Is onInitialize() the best place where create components?

Best practices with subclassing and subpackaging
Hi, I have an application with several pages, mounted in webapplication, that do not have markup file associated. The markup file is selected using variations in the parent class. I would like to split pages in subpackages but if I move the markup file (ParentPageClass_variation.html) in the subpackages too, it doesn't work, obviously. So, some questions. Is it a good practice in wicket this kind of subclassing? Is there a way to override the resolving of the markup filename? I took a look to the apidocs without success.

Re: Does wicket:link tag work inside pages in different packages?
Yes, you are right. I will do in that way. The fact is I have a similar problem with some menu panels with several links. I just wanted to do the easiest thing.

Re: Does wicket:link tag work inside pages in different packages?
Yes, I read it. Does it mean that have to do a different header panel for every suppages level (using "../(../)HomePage.html" link)?

Does wicket:link tag work inside pages in different packages?
Hi, I have an header panel with a link to the homepage of the site. This panel is included in every page of the site. If I use the tag for that link it works fine (for example, it is disabled in the homepage) for the pages in the same package of the Homepage class. If I am on a page inside another package (subpackage in my case) the link became the name of that package plus the href specified in the html panel. For example: ... In a page inside package "subpackage" the link is: "subpackage/HomePage.html" and not "../". What I'm doing wrong?

Dealing with 3 choice components
I have a form with with 3 choice components:
A) DropDownChoice
B) DropDownChoice
C) ListMultipleChoice
The values of B depend on selected value of A.
The values of C depend on selected values of A and B
I override the wantOnSelectionChangedNotifications() and
onSelectionChanged() methods of A and B.
A#onSelectionChanged
@Override
protected void onSelectionChanged(IntegerSelectChoice newSelection) {
super.onSelectionChanged(newSelection);
SearchForm.this.getModelObject().setInstrument(null);
SearchForm.this.getModelObject().setParams(null);
}
B#onSelectionChanged
@Override
protected void onSelectionChanged(IntegerSelectChoice newSelection) {
super.onSelectionChanged(newSelection);
SearchForm.this.getModelObject().setParams(null);
}
In A I set to null the model value of both B and C.
In B I set to null the model value only of B.
This code works only on the startup of the form. When I change the value
in A the list of C become empty. I have to change the value of B to fill C.
How can I manage this?
