Re: Efficiency of 1.5 MountMapper weighted/matching algorithm
We have already discussed this problem before. I agree that caching will improve the performance and I'll try to implement it soon. Topicus' (Martijn's daily job) biggest application have ~ 700 mounted pages and this code is not a hotspot for them, that's why no one spend time on optimizing it so far.

Re: can i get the selected value from DropdownChoice not in the onSubmit method of a form
please, note that wicket-users forum is plenty full of examples like
this, so the forum, and so the official wicket-examples. a good
suggestion is to deeply look there for an answer before posting.
as suggested before, may you add onchangeajaxbehaviour to your
dropdownchoice, as shown in the following example:
html:
http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd";
>
Volvo
Saab
Mercedes
Audi
java:
@SuppressWarnings("serial")
public class DropDownChoicePage extends WebPage {
private Entity selected;
public DropDownChoicePage() {
List list = Arrays.asList(new Entity[] { new
Entity("coco"),
new Entity("liso"), new Entity("pata"), new Entity("tero") });
DropDownChoice select = new
DropDownChoice("select",
new PropertyModel(this, "selected"), list);
select.setNullValid(true);
select.add(new OnChangeAjaxBehavior() {
private static final long serialVersionUID = 1L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
System.out.println(selected);
}
});
add(select);
}
public void setSelected(Entity selected) {
this.selected = selected;
}
public class Entity implements Serializable {

}
public String getId() {

Validating in form returns always error but textfield has a value
I'm using a LinkTree and to each node a panel is referenced. Both is embedded in a form component. The panels have textfields. When using a submit button or a SubmitLink the input of the textfields is valid and then also validation is valid. But: My intension is also to validate the form each time the node is changed. So I'm using the method form.validate() directly. But the textfields have all null input! --> validation error also when there is a value inside textfield. Why the (raw)input is not recognized (the textfield model is ok) ? what I'm doing wrong. How can I solve this problem? thank you for hints!

Re: Validating in form returns always error but textfield has a value
is the form submitted each time a node is changed? if not, then it could be normal you read nulls, as the values are still on browser, but havent flown to server.

Re: Validating in form returns always error but textfield has a value
Yes, each time I change the node the form is submitted. The textfields in the panel are initialized via PropertyModel and are set to required. When I want to change the node I call validate() but the rawInput of textfields is null. --> form.hasError() is always true, but there are values in the textfields. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Validating-in-form-returns-always-error-but-textfield-has-a-value-tp3912361p3912457.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

Redirect to External Application
Hi,
we have the following use case - we need to redirect to an external
application, that handles authorization for us (cookie creation etc.).
For this, we need to redirect to this application and handle a callback url,
where this external application redirects after succesful login.
I tried the following (very simplified, but worked in 1.4 but not in 1.5):
String url =
((HttpServletRequest)RequestCycle.get().getRequest().getContainerRequest()).getRequestURL().toString();
throw new
RedirectToUrlException("http://someexternalapplication?jumpBackToMyApplicationURL="+url);
In 1.5 I get 404 - since this url looks like this:
http://localhost:8080/wicket/page, which is not a legal url, since the page
identifier is missing.
I would love to hear some thoughts, how to handle this in 1.5,
thank you very much.
Martin

If you had a variety of main and side bar menus on each page that had links to say 40 or so Bookmarkable pages that would mean each page render would result in building 40 weight/mount pair collections, each with 700 entries - and then throwing them away after each bookmarkable page link has been created. I realize it may not be a hotspot but, intuitively at least, it sounds like your new caching improvement will help reduce CPU load.

That is, the form is enabled for an "Admin" (full permission to change things) and disabled for a "Read-only User" (not allowed to change anything). 2.

Here are some code snippets. When clicking on a tree node I validate the form.. If no errors I update the form component models. The class MyMutableTreeNode extends DefaultMutableTreeNode. Each node references an own panel component. getNodeEntryDetail() returns the panel referenced by the node. Where is the difference to a SubmitLink call.
