Re: InlineFrame: IPageLink object looses reference to page after deserialiations

Re: [OT] Book/pointers on caching
Caching wicket components is a really bad idea as you will run into concurrency issues. IMHO the caching strategy depends on the how immutable the data is, its transaction isolation (read-only, read-write, etc) and what performance problem you are encountering (Cartesian product, N+1 select, etc). Have a look at the Java Persistence with Hibernate for a primer on the subject. Cheers, James.

Re: How to prevent a flickering when Ajax updates an Image
Hi,
I tried some of your suggestions and I came up with a working sollution. But
I have the feeling I can do better than that.
Waht I did is having two of my images at the same time, both wrapped by a
div layer. One div layer is hidden, the other is visible. When something
happens the non visible image gets updated and when the update is done it
will be set to visible and the prior visible will be set to hidden.
I think the concept is ok... but I'd rather work with just one div layer and
copy the image to the visible area via javascript. But I couldn't figure out
how to do that.
Here is some code to show what I did in detail:
This is my image (I have two of theese, map1 and map 2)
NonCachingImage map = new NonCachingImage(map1, new
PropertyModel(this, imageResourceMap)){
private static final long serialVersionUID = 1L;
@Override
protected void onBeforeRender() {
generateMap();
super.onBeforeRender();
}
};
map.setOutputMarkupId(true);
map.add(new AjaxEventBehavior(onLoad){
@Override
protected void onEvent(AjaxRequestTarget target) {
}
@Override
protected CharSequence getSuccessScript() {
logger.debug(successscript;);
return hideShowElement('divMap2', 'divMap1');;
}
});
I don't know if the SuccessScript is the right place for it... but it
worked.
This is my markup
div id=divMapContainer style=position: absolute;
div id=divMap1 style=display: block; position:
absolute; left: 10px;
top: 10px;
im.g id=map1 wicket:id = map1 width=400 height=300
onMouseMove='onMove(this, event)'/
/div
div id=divMap2 style=display: none; position:
absolute; left: 10px;
top: 10px;
im.g id=map2 wicket:id = map2 width=400
height=300/
/div
/div
The question now is:
Is the thing I did ok? or is the a better way of doing it?
Right now I have almost no flicker (90% flicker free)... but I think it can
do 100%.

And I would probably make a hidden container in which the image loads(so
that the browser has it loaded), and then use scriptaculous to load it as
a
replacement for the image..

Hi,
well yes, I understand what you say. But I am not that deep into wicket
an
ajax yet... so right now, I don't know what to do next.
Could you, or anyone else, give some details how to submit the image to
the
client-browser and not show it before it's fully loaded?
thx

Hi there,
i have a page that updates an image through a ajax request.
Some Code first:
public class MyPage extends WebPage{
private RenderedDynamicImageResource imageResourceMap;
...
NonCachingImage map = new NonCachingImage(map, new
PropertyModel(this,
imageResourceMap)){
private static final long serialVersionUID = 1L;
@Override
protected void onBeforeRender() {
generateMap();
super.onBeforeRender();
}
};
AjaxLink lNorth = new AjaxLink(north_link, this.getModel()) {
@Override
public void onClick(AjaxRequestTarget target) {
...
target.addComponent(Overview.this.get(map));
}
};
private void generateMap(){
HexCoordinates hc = (HexCoordinates) getModelObject();
imageResourceMap = mapGenerationService.getMap(hc.getX(),
hc.getY(),
6);
}
...
}
html markup is this
...
...
So my problem is, everytime I click the ajaxlink the image gets
updated
correctly but it flickers. Which is very unpleasant. Doesn't matter if
I
use
IE or FF. Both show the flickering effect.
Any help is greatly appreciated.
Thanx
Santo.

wicket log4j MDC
Hi I would like to add MDC information(i.e. user login) to my loggs (log4j). To do that I have to call MDC.put at the beggining of request handling.

Extend layout of a page
Hi, I am searching for a way to extend the design of a page without changing the page itself. That means, something like the Decorator Pattern. I have a page with for example just a table in it. In another project (or the same project) this page should have a navigation on the top. My current solution is the following: I have a base page which is segmented into five panels: header, left, main, right and footer. Now if a navigation is needed, a menu panel will be added to the header panel. Is there a better way? tia Pt! Schon vom neuen WEB.DE MultiMessenger gehört?

Re: wicket log4j MDC
You can create a custom request cycle which extends the Wicket
WebRequestCycle. This logs the user name in your logs of the user who does
the request.
public class MyRequestCycle extends WebRequestCycle {
private static final Logger logger =
Logger.getLogger(MyRequestCycle.class);
public static final String USER = USER;
private Time requestStart;
private Time requestEnd;
/**
* Creates a new request cycle.
*
* @param application the application
* @param request the request
* @param response the response
*/
public MyRequestCycle(WebApplication application, WebRequest request,
Response response) {
super(application, request, response);
}
@Override
protected void onBeginRequest() {
requestStart = Time.now();
MDC.put(USER, YourUser.getUsername());
logger.debug(Begin Request);
}
@Override
protected void onEndRequest() {
requestEnd = Time.now();
logger.debug(End Request. Request took +
TimeFrame.valueOf(requestStart, requestEnd).getDuration());
MDC.remove(USER);
}
@Override
public Page onRuntimeException(Page page, RuntimeException e) {
return null;
}
}

visibility Behavior?
I am working on some security integration (Ki/wicket), and am looking at a general way to set component visibility based on the user permissions/roles etc. Of course I could do: component.setVisible( false ), but that gets really verbose when 'false' can be a rather long statement. Wicket-auth-roles uses the authorize actions annotation to disable RENDER/ENABLE I understand how to apply that if I construct a class with the annotation, but how would I apply something like that to an arbitrary component? Could this be implemented with a Behavior? Perhaps, beforeRender() could set enabled/visibility and cleanup() would restore it? It would be great to be able to do: WebMarkupContainer stuff = new WebMarkupContainer( stats ); stats.add( new AuthorizationConstraint( view: stats ); or something like that. Any pointers? Am I missing another preferred way to do this? thanks ryan - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: visibility Behavior?
Hi Ryan,
works nice with behaviors. I use somehing like the following to
show/hide components based on my user roles:
public class MySecurityBehavior extends AbstractBehavior {
private boolean isVisible() {
// your logic for security checks...
}
@Override
public void bind(Component component) {
boolean visible = isVisible();
component.setVisibilityAllowed(visible);
component.setVisible(visible);
}
}
then just add that to your components.

Re: RadioGroup lost value after onError form
use repeatingview instead of listview, or call setreuseitems on the

Take for instance a page with many news blocks for different topics, a recently added content block, polls, the list of all active users, etc. Fetching all this data requires tons of queries to the backend. I understand that I need some caching mechanism. And as many have pointed out on this list, it is preferable to not do this in the presentation layer (caching Wicket components) but to move the caching to the business logic or persistence layer. So my Wicket models still make the same calls, like service.find(blabla), but behind the scenes, a cache speeds up the access. The question is just: what are good caching strategies? When to update the cache? Should the cache itself know when to invalidate entries? Etc. Is there any sample code, articles, or books on this that you can recommend?

Re: How do I call alert(); rather than using .info or .error of Component
Hi John,
Normally the error, info, fatal messages on Component enter the message
into the List of Feedback messages in the Session. The messages are
accumulated during the pre render phase of the request cycle and then
the entire list is detached at the end of the request cycle. see
org.apache.wicket.Session#cleanupFeedbackMessages()
The easy way would be to extend the default FeedbackPanel (or something
custom from the IFeedback interface) which would take care of consuming
the messages and apply your implementation to render the errors out as a
javascript alert.

Mike

This is really annoying. Is there a way to remove that? And what is this ModificationWatcher Task? Thanks Thierry Sent from: Montreal Quebec Canada.

Re: Annoying ModificationWatcher Task... debug log line
Thanks for the info! I think I remember seeing somewhere that we can turn off this auto reload feature... I really don't need that for the moment. Does anybody know how to do that?

Why should the programmer specify how a SingleSelectChoice looks?
What I really like about Wicket is that it -- much more than JSPs -- allows the separation of HTML markup from Java code. No c:ifing with a Domain Specific Language like JTSL (or Velocity macros) inside HTML markup and side-by-side with javascript. In Wicket, in contrast, HTML markup contains only HTML and Wicket tags, which look just like HTML tags. That's it. But I think this could be taken a bit farther, and I'd like the list's thoughts on a proposal. Wicket imposes one constraint on markup: roughly, any HTML element with a wicket:id attribute must match a Wicket Component, a Java Object, in the Java code. More precisely, the HTML element tree (considering only wicket:id elements) must (with a few exceptions) match the Wicket Component tree rooted at the Wicket Page. But -- in my opinion -- Wicket goes a bit too far in enforcing this. In particular, there are at least three ways to allow a web page user to select one thing from a list of several things: A drop down list, like this: selectoptionone/optionoptiontwo/option/select A list that scrolls but doesn't drop down, as above but with the select tag given a size attribute. Or, a group of radio buttons, like this: input type=radioone/inputinput type=radiotwo/input To the application and its programmer, these are all the same functionality: present some choices, find out which SINGLE choice the user selects. How that looks on the page is immaterial to the application's functionality. To the page designer, these are all different, presenting different looks, talking up different amounts of screen space, each with a slightly different learning curve for the user. In particular, novice web users may not even realize the drop down is a choice and can be clicked on, dropped down, and changed. If the page designer decides that, say, he's dealing with a less web-savvy population, and wants to change the dropdown to a group of radio buttons, someone has to send a change request to the Java programmer. Then the programmer has to change some or all instances of one class derived from AbstractSingleSelectChoice (e.g., DropDownChoice) to another (e.g., RadioChoice). Which shouldn't happen; the way the choice is rendered has nothing to do with the the page's functionality. In Model-View-Controller terms, the rendered look is purely up to the Model; the functionality purely the domain of the Controller. Would it be useful to have a Wicket Component that automatically rendered whichever type look the page designer wants, further decoupling web page designer's View from Programmer's Controller, while providing a single uniform functional interface to the application?

there isnt anything really stopping you from doing this. afaict you already have all the wicket hooks to do this. -igor On Mon, Mar 30, 2009 at 2:15 PM, T P D li...@diffenbach.org wrote: What I really like about Wicket is that it -- much more than JSPs -- allows the separation of HTML markup from Java code.

Re: Why should the programmer specify how a SingleSelectChoice looks?
Well, actually, I have done it, by abstracting out the rendering by having onTagComponent and onTagComponentBody, in a class derived from AbstractSingleSelectChoice, delegate to a GOF Strategy Pattern. I then have four strategies: one each for dropdown, dropdownlist, and radiochoice, and a fourth strategy that delegates to one of the other three depending on the tag in the HTML markup file. (And of course other programmers can derive from the AbstractStrategy to do whatever they want.) Using any of the first three strategies essentially gives the user the functionality of the existing Wicket classes DropDownChoice, ListChoice, and RadioChoice, tying that instance of the Component to one strategy. Using the fourth allows the rendering to vary based on the HTML markup. It renders nicely. But I wanted to broach this as is this a good idea, and only if people said yes, then talk about my implementation, and extending the same pattern to the multiple choice Components.

Tree navigation panel
Hello, I'm looking for a tree navigation panel for wicket (1.4). I know the AJAX panel, but I'd like to have something that works without JavaScript. After consulting the API docs and looking for tree classes, I think to write my own navigation tree panel would cost a couple of hours. So is there an easy way to get a navigation tree? What I need looks like this: The structure * root ** FolderA *** File1 *** File2 *** File3 ** FolderB *** File9 *** File8 ** FolderC should be converted to something like the following html (FolderA elapsed): ul lia href=...root/abr/ lia href=...FolderA/abr/ lia href=...File1/a/li lia href=...File2/a/li lia href=...File3/a/li /li lia href=...FolderB/a/li lia href=...FolderC/a/li /li /ul Thanks for your help!

Re: Tree navigation panel
trees in wicket work with or without javascript. you can set the tree mode to fallback and get the best of both worlds - ajax when supported, regular links when not. -igor On Mon, Mar 30, 2009 at 3:30 PM, Christian Helmbold christian.helmb...@yahoo.de wrote: Hello, I'm looking for a tree navigation panel for wicket (1.4).

how to display a BookmarkableLink so it can't be clicked
