Re: [REQUEST] Integrate Wicket and Nutch for Google Summer of Code 2014
Hi Lewis, I'm glad you contacted us! I see the ticket has been opened for few years now. This is a shame! We should have coordinated this task much earlier! Nutch could be the next Apache project that uses Wicket for its web administration needs. There are few other projects already. I've added myself as a watcher to the ticket and I will be glad to help with Wicket expertize. If there is any interest in Wicket mailing list about GSOC we will definitely link to your task!

Re: WicketTester.isRenderedPage() in 6.13
I have created a new page with link and then execute: DummyBasePage page = new DummyBasePage(action); startPage(page); clickLink(page.getActionLink()); where action link is a link to another page. But it is still not working, only DummyBasePage is rendered. Then I look into WicketTester code and I have found that there are hard coded links' classes!

I am actually wondering how to hide this API from the developer in the tests. The idea of the tester is to simulate sending requests to the pages/resources. tester.getRequestCycle().setResponsePage() doesn't test anything in the application. tester.getRequestCycle().setResponsePage() is like to replace the current page in the browser without sending request to the server and to expect for example that server push (websocket, server sent events, ...) will still work with your new page.

If you see any regressions in WicketTester since 1.4.x/1.5.x please report ticket with a test case.

[CVE-2013-2055] Apache Wicket information disclosure vulnerability
Severity: Important Vendor: The Apache Software Foundation Affected versions: Apache Wicket 1.4.22, 1.5.10 and 6.7.0 Description CVE-2013-2055https://wicket.apache.org/2014/02/06/cve-2013-2055.html : It is possible to make Wicket deliver the HTML templates in their raw/non-processed form. An attacker could see any sensitive information in the part of the HTML template that is usually ignored during rendering. For example if there is sensitive information before or after the Wicket Panel/Border's markup: [something sensitive here 1] wicket:panel [real application code] /wicket:panel [something sensitive here 2] Usually Wicket will render only the [real application code] part but by exploiting this vulnerability an attacker can see also the code with the sensitive information. The application developers are recommended to upgrade to: - Apache Wicket 1.4.23https://wicket.apache.org/2014/02/06/wicket-1.4.23-released.html - Apache Wicket 1.5.11https://wicket.apache.org/2014/02/06/wicket-1.5.11-released.html - Apache Wicket 6.8.0https://wicket.apache.org/2013/05/17/wicket-6.8.0-released.html and/or to remove any sensitive information in the HTML templates.

Strange: Ajax-updates from a form inside a modal dialogue echoed in the page underneath
I've just spent several hours trying to figure out what's going wrong here without any success. I am investigating a very strange effect: In my application I have a search panel in which several dropdowns are used to select search settings. Some of these settings depend on each other, so that they have their change events digested by AjaxFormComponentUpdatingBehavior. Now on a particular page I use a similar form for picking objects using a dialogue in a modal window. For convenience I've extracted the search form to a separate class which is now used in both search panels. Now, when the modal window is opened and the user selects entries from the dropdowns, the ajax updates caused by the above behaviours are echoed to the (still visible) search panel in the underlying page, i.e., selections in its dropdowns change etc. I checked the following things: - there are no hand-assigned markup IDs, i.e. the Ajax updates operate on unique IDs. - when I embed the panel in the page instead of a dialogue, the effect disappears (however this is no option my customer would accept) - using dumb copy-and-paste instead of inheritance for the two search forms does not help, i.e. the effect does not disappear Since the application I'm dealing with is pretty complex, also for confidence reasons, I can't really give any code examples here. I am using Wicket 6.12. Has anyone ever experienced an effect like this? Any workaround known? I feel pretty clueless with this problem..

Visual HTML diff in Wicket?
In my system there is an editorial submodule for creating HTML contents. As I am about to add a versioning history to it, I'd like to add some kind of visualisation of what changed from edit to edit.

Re: Strange: Ajax-updates from a form inside a modal dialogue echoed in the page underneath
Hi, Check the Ajax response after selecting a component. It contains ajax-response with component id=... elements. The id attribute is used to find the old HTML element and to replace it with the new content. Since Wicket uses document.getElementByid() to find the old one I see no way how it will replace/update more than one HTML element in the page per component. So I guess there are components for both the elements in the modal and in the page. The best is to debug it and fix it. A workaround is to use a Page for the Modal instead of a Panel.

I believe we have memory leak in our application maybe there is best practices how to deal with Models and JPA entities to resolve this? Thanks in advance -- WBR Maxim aka solomax
Re: Strange: Ajax-updates from a form inside a modal dialogue echoed in the page underneath
Martin, thanks a lot for your advice! On Thu, February 06, 2014, Martin Grigorov wrote: Check the Ajax response after selecting a component. It contains ajax-response with component id=... elements. The id attribute is used to find the old HTML element and to replace it with the new content. Since Wicket uses document.getElementByid() to find the old one I see no way how it will replace/update more than one HTML element in the page per component. So I guess there are components for both the elements in the modal and in the page. The best is to debug it and fix it. A workaround is to use a Page for the Modal instead of a Panel. Using the Ajax Debug panel I could track the problem down rather easily. While the actual form components were clean I found out that their surrounding containers, some of which were, too, updated using Ajax were given fixed markup IDs from within the Java code, so that I had two of them with the same IDs. Need to do a 'git blame' on that one :) Cheers, M'bert -- --- / http://herbert.the-little-red-haired-girl.org / - =+= manche meinen, lechts und rinks kann man nicht velwechsern. werch ein illtum! -- elnst jandr - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
RE: Memory leaks best practices
If you have Models or Components as fields in you classes you should override
the classes method onDetach.
Example:
Public class MyPanel extends Panel {
private final IModelObject objectModel;
public MyPanel(String id, IModelObject objectModel) {
super(id,objectModel);
this.objectModel = objectModel;
}
@Override
protected void onDetach() {
super.onDetach();
objectModel.detach();
}
}

Component c = super.getHeader(id, parent, wizard);
c.get(summary).setEscapeModelStrings(false);

Re: Memory leaks best practices
Hi, OOM in PermGen is not what you ask for. If you leak normal memory than the error would be with heap space. PermGen memory is used to keep the Class instances and interned Strings. If you deploy your app for first time then most probably you just need to set the proper initial and max value : -XX:PermSize and -XX:MaxPermSize. Use JConsole to see what size you need. If this error happens on redeploy then most probably you have a ClassLoader memory leak, i.e. you keep references to Class instances and they cannot be released so the PermGen is overloaded. Those are very tricky to be debugged.

Re: Choice Renderers Display Issue After Submit
I answered my own question! I'm a dork. But, for others that might have this
same problem:
Because the object in the SearchCriteria bean that you are selecting
(selectedPeriod) is now a different type of Object than a String, if you
recreate your list of objects to feed to the DropDownChoice (as I do at
various parts of the code), you will need to implement a proper EQUALS
method in your Object (PeriodBean). Otherwise, your selection connected to
the model (selectedPeriod) is not equal to the object sitting in the list of
options (because you recreated the list). That means your choice is not
shown in the DropDownChoice anymore (it says to Select an Option instead).
So, PeriodBean needed this:
@Override
public boolean equals(final Object obj) {
if (obj == this) {
return true;
} else if (obj == null) {
return false;
} else if (obj instanceof PeriodBean) {
PeriodBean other = (PeriodBean) obj;
return other.getPeriodIndex().equals(getPeriodIndex());
}
return false;
}

Re: Precondition Check
Hi,
I see you don't have custom AjaxRequestAttributes, so no custom
preconditions.
Wicket has just one default precondition - it will execute the Ajax call
only if the related HTML element (the link) is in the current document.
https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/ajax/res/js/wicket-ajax-jquery.js?source=c#L508

Or whoever maintains mod_proxy_wstunnel. If you split http and ws to be in different mappings (e.g. /openmeetings (for http) and /ws-openmeetings (for ws)) then you will have to use two filter elements in your web.xml, one with WicketFilter and another with JettyWebSocketFilter. The problem here is that both of them will have their own Application and Session instances. I think it should be easy for HTTPD to differentiate between the protocols and use the correct proxy settings.

Re: Precondition Check
you can click on it and the event listener can delay the actual Ajax call
as much as it wants (Wicket's AjaxChannel.QUEUE does exactly this).
E.g. click two times on the link, the first click fires Ajax call (the
second click waits), its response removes the link from the DOM (or
replaces it), then the second click event will be prevented because its
event.target is no more in the DOM

Hi,
I see you don't have custom AjaxRequestAttributes, so no custom
preconditions.
Wicket has just one default precondition - it will execute the Ajax call
only if the related HTML element (the link) is in the current document.
https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/ajax/res/js/wicket-ajax-jquery.js?source=c#L508
Put a breakpoint in Dev Tools/Firebug and see why the link is not in the
document.

Re: Web Sockets proxying
Hi Maxim, It is shame that none of the HTTPD developers responded. It looks Eric Covener knows as much as I do about mod_proxy_wstunnel ...

I see you don't have custom AjaxRequestAttributes, so no custom
preconditions.
Wicket has just one default precondition - it will execute the Ajax
call only if the related HTML element (the link) is in the current
document.
https://github.com/apache/wicket/blob/master/wicket-core/src/main/ja
va
/org/apache/wicket/ajax/res/js/wicket-ajax-jquery.js?source=c#L508
Put a breakpoint in Dev Tools/Firebug and see why the link is not in
the document.

Datepicker to pick just the month
Hi, I am developing a webapp where at some certain point we need to pick just the month of a date. I have tried to create a DatePicker with date format = , and it works ok when it loads the date from the Database, if the month of the date stored is february, for example, it renders February correct, but if I try to pick another month, for example March, then in the date field it shows 03 and it shows an error pointing that the date format is not correct. Isn't it allowed to use the format? MMM doesn't work either... Thanks!

Re: Datepicker to pick just the month
Hi, I assume you use wicket-datetime module. You will have to consult with YUI 2.x docs to see what is supported - http://yui.github.io/yui2/ https://github.com/l0rdn1kk0n/wicket-bootstrap uses this datepicker - http://bootstrap-datepicker.readthedocs.org/en/latest/options.html#format Wicket JQuery UI project provides integration with JQuery UI datepicker.

Re: I need a library for drawing graph
Hi, arbor.js is a really nice library based on jQuery. I don't know if it can suit your need. http://arborjs.org/ I am not aware of an existing wicket integration but it should be feasible... There is several jQuery / Wicket integrations (boostrap, jquery-ui, etc) you can look at for inspiration... Best regards, Sebastien.

replaceWith method in Panel not working with AjaxLazyLoadPanel
Hi, I have the following panel layout: SomeOtherPanel AjaxLazyLoadPanel Panel loading with AjaxLazyLoadPanel PanelToReplace I am trying to replace PanelToReplace using replaceWith within IndicatingAjaxFallbackLink onClick method but I get the message: Component '[EmptyPanel [Component id = additionalInfo]]' with markupid: 'additionalInfo3e' not rendered because it was already removed from page. Using the same approach, I have replaced SomeOtherPanel which is not inside AjaxLazyLoadPanel and it works fine. So it seems I cannot use replaceWith when the Panel is within AjaxLazyLoadPanel. Is there an alternative way to do this? Regards Vishal - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Choice Renderers Display Issue After Submit
Hi guys!
I'm using a ChoiceRenderer for the first time, and am having a slight
problem with it. Any help would be *greatly* appreciated!
I have a DropDownChoice used to select a particular PeriodBean object which
uses a ChoiceRenderer to properly display only the Description string of
the object. The issue is that once a selection is made and I submit the form
(works properly), the DropDownChoice goes back to not having a selection
displayed (because, I'm assuming, it doesn't know how to take the item in
the property model and display it in the DropDownChoice). How do I make it
continue to properly display the selected PeriodBean Description?
Here's code (simplified version of mine):
// This is what a PeriodBean looks like:
public class PeriodBean implements Serializable {
private String periodIndex;
private String periodDescription;
public String getPeriodIndex() {
return periodIndex;
}
public void setPeriodIndex(String periodIndex) {
this.periodIndex = periodIndex;
}
public String getPeriodDescription() {
return periodDescription;
}
public void setPeriodDescription(String periodDescription) {
this.periodDescription = periodDescription;
}
}
// This is what my SearchCriteriaBean looks like (stores the selected value
from the dropdown):
public class SearchCriteriaBean implements Serializable {
private PeriodBean selectedPeriod;
public PeriodBean getSelectedPeriod() {
return performancePeriod;
}
public void setSelectedPeriod(PeriodBean periodBean ) {
this.selectedPeriod= periodBean;
}
}
// This is a PeriodList item that creates the list of acceptable choices for
my dropdown
public class PeriodList extends
AbstractReadOnlyModelListlt;? extends PeriodBean {
public PeriodList() {
super();
}
@Override
public ListPeriodBean getObject() {
ListPeriodBean pendings = new ArrayListPeriodBean();
// Go to the database and do some stuff to get the proper list of
selectable pending periods
return pendingPeriods;
}
public IteratorPeriodBean iterator() {
ListPeriodBean pendings = this.getObject();
return pendings.iterator();
}
};
// And this is JAVA in the Page itself:
// Create a search criteria
SearchCriteriaBean searchCriteria = new SearchCriteriaBean(); //Defined
above
// Create a list
PeriodList periodChoices = new PeriodList(); //Defined above
// Create my dropdown and choice renderer to display the period description
ChoiceRendererPeriodBean choiceRenderer = new ChoiceRendererPeriodBean(
periodDescription, periodIndex);
DropDownChoicePeriodBean periodChoice = new DropDownChoicePeriodBean(
periodChoice,
new PropertyModelPeriodBean(searchCriteria, selectedPeriod),
periodChoices, choiceRenderer);
periodChoice.setOutputMarkupId(true);
periodChoice.setRequired(true);
form.add(periodChoice); // There is a form on this page but I am not showing
for simplicity.
