Re: Glue for composing panels
Hi Frank,
We use the same approach as you. We have found one disadvantage, which
relates to references to components created by subclasses.
I'll demostrate it (problem and solution) in the following example:
class BasePage extends Page
{
/** Component created by subclass */
private Component component;
private boolean componentsAssembled = false;
/** Let the assemple method to set componentsAssembled flag */
private void assembleComponents()
{
component = createComponent();
...
componentsAssembled = true;
}
protected abstract Component createComponent();
@Override
void onBeforeRender() {
if ( !componentsAssembled ) {
assembleComponents();
}
super.onBeforeRender(); // Or whatever else is needed
}
/** Method uses assambelComponents() to ensure, that component is created */
public Component getComponent()
{
if(component == null)
{
assembleComponents();
}
return component;
}
/** public method delegete to referenced component. Uses safe
getComponent() method */
public void setComponentModel(IModel? model)
{
getComponent().setModel(model);
}

2009/10/29 Frank Silbermann frank.silberm...@fedex.com:
I was discussing glue for composing reusable panels into web pages on
the blog of Erik van Oosten
(http://blog.jteam.nl/2009/09/16/wicket-dos-and-donts/).
I told him that my approach had been to create an abstract base page
that constructs the common elements while leaving place-holders for
page-specific panels by defining methods such as:
abstract Panel createUpperLeftPanel (String wicketID);
abstract Panel createLowerRightPanel(String wicketID);
and having the base page's constructor say things like:
Panel p1 = createUpperLeftPanel(a_wicket_id);
add(p1);
...
Add( createUpperRightPanel(another_wicket_id) );
The child page's contribution would be the implementation of the
abstract methods.
I explained that I preferred this to mark-up inheritance because I could
add to the base page in any number places (not just one place), the
compiler would tell the child-page writer exactly what panels were
needed, and most importantly, no additional mark-up whatsoever would
need to be associated with any of the child pages. (Panel classes used
by the child page would of course have their associated mark-up.)
Eric and others explained what a bad idea it is for constructors to call
overridable methods -- they execute before the child-page's properties
have been set. I usually got away with this, but I admit I was burnt a
few times. Recently, I wondered whether there might be a simple fix for
the constructor-calls-overridable-method problem, such as:
(a) Move the base page's component tree construction out of the
constructor, and put it into the method:
private void assembleComponents() {
...
}
(b) Add the property:
private boolean componentsAssembled = false;
(c) Override as follows to construct the component tree after the class
constructors finish:
�...@override
void onBeforeRender() {
if ( !componentsAssembled ) {
assembleComponents();
componentsAssembled = true;
}
super.onBeforeRender(); // Or whatever else is needed
}
Then component construction would wait until the properties in both the
parent and the subclass had been set. I'd no longer have the problem
associated with calling abstract methods from the constructor.
Do you see any disadvantages to this approach? Is there a more
appropriate hook upon which to hang my base page's component-tree
assembly?
If it _is_ a good approach, is there any reason the Wicket designers
chose not to create an overrideable method in the Component class that
is called just once after constructors terminate, and tell developers
that this is where the component tree should be created?

DefaultObjectStreamFactory | Re: AccessControlException with Wicket on Google App Engine (GAE)
just to circumvent the problem for a while, I am thinking of the following workaround: what would be the implications if I change the implementation of IObjectStreamFactor.DefaultObjectStreamFactory so that newObjectInputStream() and newObjectOutputStream return the regular JDK ObjectInputStream and ObjectOutputStream, respectively? To my mind, this would eliminate the AccessControlException problem since I am not subclassing ObjectInputStream and ObjectOutputStream. thanks, andr On 30.10.2009 10:27, A.

So, that refresh is delayed a lot... but now that I look to it again I see
there is an stop() method on AbstractAjaxTimerBehavior.

Okay,
So I got it working. As you suggest - stop() works. I then also
store the behavior so that it can be removed permanently on a later
Ajax trip. That way I can keep adding and removing timers with
different intervals.
Thanks!

RE: Glue for composing panels
If I understand you correctly, Michal, you don't want to set the component's
model once and for all as it is being created, and you're worried that the
model-setting method might be called before the first onBeforeRender().
That's just an example, I guess, so perhaps the general concern is that you
might need to access a component for whatever reason before the first call to
onBeforeRender().
Therefore, _any_ attempt to access a component after constructors have
terminated should trigger construction of the component tree if necessary.
Is that the idea?
It sure would be nice to have an honest to goodness post-constructors event on
which I could hang the component tree creation -- then we wouldn't have to
worry about this.
In my use of Wicket, I've always set a component's model at the time that
component was created -- I've never had to swap out a model in a separate
operation. If the data to be displayed changes dynamically, I've always simply
used a model which took that into account.
Is that just a different style of programming? Or are there circumstances
beyond my limited experience which would require one to access a component
before the first call to onBeforeRender()?

Re: Bookmarkable images from db
Hi Alex, I check SharedResources, but as I understand it I would have to add there a Resource object for each image. After checking again the javadoc there might be another way. Display each image with Image constructor that takes ValueMap and provide there some image identification. Add a single Resource object for all images and from getResourceStream() implementation to call getParameters() which will return the same parameters passed to Image constructor and tell me which image to return. Will this work?

Wicket Examples as portlets in Liferay
Hi,
I try to get the wicket-examples-WAR running as portlets in Liferay
according to my description here:
http://cwiki.apache.org/confluence/display/WICKET/Wicket+Examples+as+portlets
But after drag'n'drop e.g. the echo example portlet, it is not shown.
When I look in the HTML-source of the portal page I see:
div id=p_p_id_EchoApplication_WAR_wicketexamples_ class=portlet-boundary

Re: OSGi Wicket
Hi,
The very simple way to solve such problems is:
1. Add: DynamicImport-Package: *
to MANIFEST.MF file in bundle with Wicket.
2. Use customized implementation of IClassResolver which falls back to
Wicket bundle ClassLoader, eg:
try {
ClassLoader loader = Thread.currentThread().getContextClassLoader();
if (loader == null) {
loader = DefaultClassResolver.class.getClassLoader();
clazz = loader.loadClass(classname);
} else {
try {
clazz = loader.loadClass(classname);
} catch (ClassNotFoundException e) {
loader = DefaultClassResolver.class.getClassLoader();
clazz = loader.loadClass(classname);
}
}
}
We are using this approach in our applications and everything works
like a charm (0 serialization related problems) :).
Maybe this is not the best way and maybe not very elegant but it uses
OSGi standard mechanism, nothing Equinox specific.

pax-wicket does solve this problem (using proper OSGi), but I have never

Re: Glue for composing panels
Yes Frank, model-setting method was just an example how to access a
component before onBeforeRender() executes.
I've only tried to point out that we set componentsAssembled = true in
assembleComponents() method. We call assembleComponents() from
get-method (for referenced component) to ensure that referenced
component has been created.
michal
2009/11/2 Frank Silbermann frank.silberm...@fedex.com:
If I understand you correctly, Michal, you don't want to set the component's
model once and for all as it is being created, and you're worried that the
model-setting method might be called before the first onBeforeRender().
That's just an example, I guess, so perhaps the general concern is that you
might need to access a component for whatever reason before the first call to
onBeforeRender().
Therefore, _any_ attempt to access a component after constructors have
terminated should trigger construction of the component tree if necessary.
Is that the idea?
It sure would be nice to have an honest to goodness post-constructors event
on which I could hang the component tree creation -- then we wouldn't have to
worry about this.
In my use of Wicket, I've always set a component's model at the time that
component was created -- I've never had to swap out a model in a separate
operation. If the data to be displayed changes dynamically, I've always
simply used a model which took that into account.
Is that just a different style of programming? Or are there circumstances
beyond my limited experience which would require one to access a component
before the first call to onBeforeRender()?

Hi Frank,
We use the same approach as you. We have found one disadvantage, which
relates to references to components created by subclasses.
I'll demostrate it (problem and solution) in the following example:
class BasePage extends Page
{
/** Component created by subclass */
private Component component;
private boolean componentsAssembled = false;
/** Let the assemple method to set componentsAssembled flag */
private void assembleComponents()
{
component = createComponent();
...
componentsAssembled = true;
}
protected abstract Component createComponent();
@Override
void onBeforeRender() {
if ( !componentsAssembled ) {
assembleComponents();
}
super.onBeforeRender(); // Or whatever else is needed
}
/** Method uses assambelComponents() to ensure, that component is created */
public Component getComponent()
{
if(component == null)
{
assembleComponents();
}
return component;
}
/** public method delegete to referenced component. Uses safe
getComponent() method */
public void setComponentModel(IModel? model)
{
getComponent().setModel(model);

2009/10/29 Frank Silbermann frank.silberm...@fedex.com:
I was discussing glue for composing reusable panels into web pages on
the blog of Erik van Oosten
(http://blog.jteam.nl/2009/09/16/wicket-dos-and-donts/).
I told him that my approach had been to create an abstract base page
that constructs the common elements while leaving place-holders for
page-specific panels by defining methods such as:
abstract Panel createUpperLeftPanel (String wicketID);
abstract Panel createLowerRightPanel(String wicketID);
and having the base page's constructor say things like:
Panel p1 = createUpperLeftPanel(a_wicket_id);
add(p1);
...
Add( createUpperRightPanel(another_wicket_id) );
The child page's contribution would be the implementation of the
abstract methods.
I explained that I preferred this to mark-up inheritance because I could
add to the base page in any number places (not just one place), the
compiler would tell the child-page writer exactly what panels were
needed, and most importantly, no additional mark-up whatsoever would
need to be associated with any of the child pages. (Panel classes used
by the child page would of course have their associated mark-up.)
Eric and others explained what a bad idea it is for constructors to call
overridable methods -- they execute before the child-page's properties
have been set. I usually got away with this, but I admit I was burnt a
few times. Recently, I wondered whether there might be a simple fix for
the constructor-calls-overridable-method problem, such as:
(a) Move the base page's component tree construction out of the
constructor, and put it into the method:
private void assembleComponents() {
...
}
(b) Add the property:
private boolean componentsAssembled = false;

Re: Bookmarkable images from db
Exactly. You can see the example posted by Vytautas Racelis earlier at this link: http://xaloon.googlecode.com/svn/trunk/xaloon-wicket-repository/src/main/java/org/xaloon/wicket/component/resource/ImageLink.java I prefer to do it this way: http://pastebin.com/m328e21ff The first example allow you to use directly an Image component, while the second allows you to build the url of any resource by name.. Alex Objelean Peter Dotchev wrote: Hi Alex, I check SharedResources, but as I understand it I would have to add there a Resource object for each image. After checking again the javadoc there might be another way. Display each image with Image constructor that takes ValueMap and provide there some image identification. Add a single Resource object for all images and from getResourceStream() implementation to call getParameters() which will return the same parameters passed to Image constructor and tell me which image to return. Will this work? Best regards, Petar Alexandru Objelean wrote: Besides the servlet, there is also a wicket way of do it: - Use shared resource, which is stateless and bookmarkable If you need more informations about this approach, search on forum or just ask... and I'll provide you with some examples of how I do it.. Alex Objelean Peter Dotchev wrote: Hi, My app allows users to upload images and I store them in JCR http://en.wikipedia.org/wiki/Content_repository_API_for_Java. I can get InputStream for each one of them. I want to display images in specific pages and I want image URLs to be stable/bookmarkable. Also I don't want these pages to use the session in any way. I checked again chapter 9 about images from Wicket In Action but such use case is not addressed there. I found that SharedResources allows for stable URLs, but I cannot register each individual image. What approach would you suggest?

Re: Wicket Release Plans for 1.5
The best would be short release cycle and very long support cycle. The latter is more important. igor.vaynberg wrote: do you guys want a release cycle that will take a year? the auto-detaching models are perfectly possible now by implementing a IDetachListener and detaching all fields that implement IDetachable via reflection. -igor On Sun, Nov 1, 2009 at 3:05 AM, Vladimir K koval...@gmail.com wrote: what about promiced auto-detaching models? may we expect it in 1.5? igor.vaynberg wrote: possibly. i think i would like this release to be as small as possible, centered around the new url stuff. once that is in release 1.5 and put the new ajax support from ng into 1.6. trying to release more and more often instead of taking over a year and a half like we did with 1.4.0 -igor On Fri, Oct 30, 2009 at 5:10 AM, Richard Allen richard.l.al...@gmail.com wrote: Is the Wicket Ajax Next Generation work going into 1.5?

Asynchronous construction of page
I am trying to find out how to load several parts (Wicket panels) of a page in parallel using Ajax. The content of these parts takes long to render but I still want the user to see the other, readily available parts of the page, with the delayed panels appearing when available. Several posts on this list indicate that AjaxLazyLoadPanel's only work synchronously. Is this still the case with the latest version/snapshot of Wicket? Is there maybe another approach available (one that still uses Wicket for the parts)? Thanks, Kaspar - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Asynchronous construction of page
if you want nonblocking you have to make each thing you are trying to load asynchronously its own page inside an iframe. the page itself can only be accessed synchronously, otherwise you would have to do your own multithreaded access handling in components...which would be horrific. -igor On Mon, Nov 2, 2009 at 1:32 PM, Kaspar Fischer kaspar.fisc...@dreizak.com wrote: I am trying to find out how to load several parts (Wicket panels) of a page in parallel using Ajax.

Page model returning null
I've got the following bits of code:
public HomePage(PageParameters parms) {
this();
Long accountId = parms.getLong(accountId);
account = new ModelEntity(Account.class, accountId);
setModel(account);
...
public class EditContactDetails extends Panel{
public EditContactDetails(String id, final ModelEntity contact){
super(id);
Form form = new Form(form, new CompoundPropertyModel(contactObj)){
@Override
protected void onSubmit(){
//do stuff
//redraw the page
HomePage hp = (HomePage) this.findPage();
ModelEntity account = (ModelEntity)
parent.getInnermostModel();
facade.logSevere(account.toString());
hp.reloadAccount(account);
}
};
...
getInnermostModel() is returning null, instead of the model I set it to when
loading the page. This all used to work until I added a panel to hierarchy
above EditContactDetails and I'm not sure why I can't get my hands on the
model now.
I'm using wicket 1.3.5. Are there circumstances where findPage() would
return a new instance of HomePage? Logging tells me that HomePage's model
does not contain null at the time it is set, and I'm not explicitly setting
it anywhere else, is there some trickery that could be resetting it for me?
Thanks for you time.

London Wicket Event at Foyles Bookshop, November 21st, 2009
We will hold our next London Wicket Event on Saturday, 21st November, from 14:45. This time we have hired The Gallery at the iconic Foyles Bookshop in central London. We again welcome guests and speakers from several countries, including at least 3 core committers, Matej, Jeremy and of course, Alastair, as well as the founders of WiQuery (Wicket-jQuery integration), Lionel Armanet and his team. Join us for some very interesting, high quality presentations and to chat with fellow Wicket users and developers at all levels. We're expecting this to be another popular event and since places are limited book and confirm early if you can make it. Details and registration are at the usual place [1]. There is a cool little Jazz cafe at Foyles too, where there'll be a live act (Femi Temowo) at 13:00 if you enjoy some Jazz guitar relaxation before your intellectual stimulation. They offer a decent range of food and drink there too. The event schedule looks like: Cemal Bayramoglu: Introduction Jeremy Thomerson (USA): Custom JavaScript Integrations with Wicket + Auto Resolvers Lionel Armanet (FR): Announcing WiQuery 1.0: Introduction Demo Matej Knopp (SK): BRIX CMS + Wicket 1.5 Developments QA Alastair Maw (UK): The Al Talk Our Regular General Wicket QA with Al and Cemal We expect to formally finish by around 19:00. I would expect the usual suspects will be heading somewhere in the neighbourhood for refreshments straight after the event, and of course you are more than welcome to join us.

Wicket Examples as portlets in Liferay
Hi sending again, as I do not see it in user list...:
Hi,
I try to get the wicket-examples-WAR running as portlets in Liferay
according to my description here:
http://cwiki.apache.org/confluence/display/WICKET/Wicket+Examples+as+portlets
But after drag'n'drop e.g. the echo example portlet, it is not shown.
When I look in the HTML-source of the portal page I see:
div id=p_p_id_EchoApplication_WAR_wicketexamples_ class=portlet-boundary
portlet-boundary_EchoApplication_WAR_wicketexamples_
a id=p_EchoApplication_WAR_wicketexamples/
script type=text/javascript

/script
/div
So it seems added, but does not contain anything to show...
What is wrong?
