RE: header resources order in 1.5.x
Hi Martin, Yes, I want to upgrade ASAP, but in current development phase it's not possible.

RE: events between pages
Thanks for a reply. Exactly. For my custom js I do simply:
target.appendJavaScript( if(window.parent != null) { window.parent. + script
+ }else{ +script +} );
because iframes are inside parent page.
Maybe there is a way to add above modification to ART with some kind of
contributor interface?

They are not part of the iframe's document and the JavaScript code
cannot find them to replace them.
It is easy to use the 'parent' in the JS code but I see no way to know
that at the server side. I.e. when using ART#add() to say that the
component is in the parent document...

RE: multiple requests and StalePageException
Problem comes from 3rd party library that does some extra actions along applet's 3 requests.

Not every component is editable, only some. Currently I have a solution where I'm using a flag (isEditMode) and some if/else constructs to create either a label or e.g. a TextField. I keep the markup for the FormComponents as Fragments or separate Panels. Any more sophisticated ideas on how to implement this? ;-) Cheers, -Tom - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
RE: multiple requests and StalePageException
Errata: this is not the code which is used to make request, but to call js.
Request are simple GETs or POSTs sometimes with attached files, they talk with
servlet.
When requests are done, js is called from applet with success, but for some
reason I get StalePageException in the request listener if in the final stage
of applet thread three requests are done. When applet makes only one request in
the final stage, everything is fine.
Simplest example of request which is used:
URL url = new URL(getDocumentBase(), spec);
HttpGet get = new HttpGet(url.toURI());
get.addHeader(Cookie, getCookie());
HttpResponse response = client.execute(get);
String responseText = EntityUtils.toString(
response.getEntity() );

RE: multiple requests and StalePageException
I have just debugged to make it sure.
Decision to refresh page is done in
org.apache.wicket.request.handler.PageProvider.getStoredPage(int pageId):
IRequestablePage storedPageInstance =
getPageSource().getPageInstance(pageId);
if (storedPageInstance != null)
{
if (pageClass == null ||
pageClass.equals(storedPageInstance.getClass()))
{
pageInstance = storedPageInstance;
pageInstanceIsFresh = false;
if (renderCount != null
pageInstance.getRenderCount() != renderCount)
{
throw new
StalePageException(pageInstance);
}
}
else
{
// the found page class doesn't match the
requested one
storedPageInstance = null;
}
}
return storedPageInstance;
If applet makes in the final stage one request, then render count from both
PageAndComponentProvider and pageInstance are equal (for example 1).
If applet makes in the final stage three requests, then render count from
PageAndComponentProvider is 1 but render count from pageInstance is 3.

Time to start a thread of my own. :) Many of Wicket's powerful repeaters depend on IDataProvider. This interface has a size() method which returns a non-null integer. This makes it easy to determine the total number of pages in a pageable view, but IMO the required computation and application complexity are not always called for. In many cases, a pageable but open-ended data view is adequate. Have you experienced this impedance mismatch yourselves? What was your solution? To elaborate on my experience: For SQL-based views, the application complexity comes from the need to construct a count(*) query with exactly the same criteria as the subsequent result query. In my experience, this pollutes DAO interfaces and IDataProvider implementation non-trivially. We initially had separate methods for counting and querying (same args), but eventually moved to a single method that returns a List,Integer-tuple with both the results and total size which our IDataProvider caches. This lets us do some Hibernate trickery to introduce a MySQL SQL_CALC_FOUND_ROWS query hint, avoiding separate count/results queries in most cases. It's still not simple, and for large counts is still expensive. The situation is worse for non-SQL data stores which don't have a fully-functional count(*) capability. We use Cassandra whose native where clause support is limited, requiring significant client-side filtering. Paging through an entire column (or CF) in this way is prohibitively expensive, especially considering our users rarely even go to page 2. To solve this, we've created a parallel set of view/paging classes that define windows using previously discovered result keys instead of start indices (tokens and column names in Cassandra). But having a full suite of IUnsizedDataProvider-based classes smells. I love that Wicket devs have solved some tough/tedious problems with DataViewBase and friends, and I want to make use of them!

It is not null. It is misleading because there is a member field and
constructor parameter with the same name.
I think that you are saying... about commented code ;-)
CompoundPropertyModel also throws an exception when null is passed so
it is immediately clear.
Is it? It seems like CompoundPropertyModel sets only its object field.
But the pasted code is hard to read with all these comments and

RE: abort loading lazy components
Hi,
It seems that probably WICKET-4227 is not fixed. I am still getting problems in
1.5.5.
If I override ajax channel like:
@Override
protected AjaxChannel getChannel() {
return new AjaxChannel( 0, AjaxChannel.Type.DROP );
}
Only last item is loaded and other items are in continuous loading state - see
WICKET-4397.
With unique channel name:
@Override
protected AjaxChannel getChannel() {
return new AjaxChannel( String.valueOf( System.currentTimeMillis() ),
AjaxChannel.Type.DROP );
}
lazy items are loaded asynchronously, however if I try to do action which
results in drop, I am getting the same exception as in Wicket-4227.

Hi,
I see no solution for your case.
Using BookmarkablePageLink works as you confirmed but I'm not
aware
of
clean way to cancel running Ajax requests and replace them with
completely new one.
XMLHttpRequest has #abort() method which cancels the request
but
this
will lead co socket close exceptions in the server side.
Right, I've already looked at XMLHttpRequest#abort(). It
wouldn't
be
a clean solution anyway.
The best approach I see is to use the same AjaxChannel name for
all
LazyLoadPanels and the AjaxLinks. The LazyLoadPanels should use
type
QUEUE and the AjaxLinks - type DROP. This way all
LazyLoadPanels
will
load sequencially and if you click an AjaxLink it will cancel
all pending LazyLoadPanels and will schedule the execution of
the
AjaxLink
after the end of the currently loading LazyLoadPanel
HTH
That's what I've already done - Wicket schedules and executes
AjaxLink action (it does not wait for other lazy panels - so far,
so good ), but then (already during handling new ajax request)
Wicket throws exception. Isn't it a Wicket bug?

RE: abort loading lazy components
Hi Martin,
Thanks for the response. I thought that simple change in existing quickstart is
better than completely new quickstart, but if it is more comfortable then no
problem :)
Created https://issues.apache.org/jira/browse/WICKET-4470
Maybe WICKET-4397 can be already closed then, as WICKET-4470 describes
everything.

Hi Michal,
Last time I tried your quickstart it was working OK with 1.5-SNAPSHOT.
The problem is that you test with a different quickstart than the
attached one in the ticket.
First I made it working at 24 Nov, then you verified at 25 Nov, then I
re-verified at 25 Jan and then you said yeah, but I changed few things
in the app locally and it breaks again.
Please create a new ticket with a failing quickstart. I want to run the
app and see the problem without any interventions from my side.

Hi,
It seems that probably WICKET-4227 is not fixed. I am still getting
problems in 1.5.5.
If I override ajax channel like:
@Override
protected AjaxChannel getChannel() {
return new AjaxChannel( 0, AjaxChannel.Type.DROP ); }
Only last item is loaded and other items are in continuous loading
state - see WICKET-4397.
With unique channel name:
@Override
protected AjaxChannel getChannel() {
return new AjaxChannel( String.valueOf(
System.currentTimeMillis() ), AjaxChannel.Type.DROP ); }
lazy items are loaded asynchronously, however if I try to do action
which results in drop, I am getting the same exception as in Wicket-
4227.

But I am getting the error:
*Unable to find component with id 'organizationList' in

I have followed the same procedure as given in various examples in
google.
So what is the cause of error?

Subject: AjaxFormComponentUpdatingBehavior after validation problem
Hello, I have such a problem with AjaxFormComponentUpdatingBehavior.
I have some DropDownChoice and a CheckBox on a Form. I need to make a
change to DropDown, when I click on CheckBox. But as I try to submit a
Form, got some error, and then click CheckBox DropDown doesn`t change.
The code looks like this:
DropDownChoiceSomeEnum dropDownz = new
DropDownChoiceSomeEnum(dropDownId,
Arrays.asList(SomeEnum.values()), new
EnumChoiceRendererSomeEnum(this));
getGenericModelObject().setValues(SomeEnum.FIRSTVALUE);
CheckBox boxz = new CheckBox(BoxId);
boxz.add(new AjaxFormComponentUpdatingBehavior(onchange)
{
@Override
protected void onUpdate(AjaxRequestTarget target) {
if (boxz.getModelObject())
{
getGenericModelObject().setValues(SomeEnum.SECONDVALUE);
get(dropDownId).setEnabled(false);
target.addComponent(get(dropDownId));
}
else
{
get(dropDownId).setEnabled(true);
target.addComponent(get(dropDownId));
}
}
@Override
protected void onError(AjaxRequestTarget target,
RuntimeException e) {
if (boxz.getModelObject())
{
getGenericModelObject().setValues(SomeEnum.SECONDVALUE);
get(dropDownId).setEnabled(false);
target.addComponent(get(dropDownId));
}
else
{
get(dropDownId).setEnabled(true);
target.addComponent(get(dropDownId));
}
super.onError(target, e);
}
});
Form form = new Form(formId, getGenericModel());
form.add(dropDownz);
form.add(boxz);
So as I said, after form validation, if errors occur, it won`t change
dropdown to SECONDVALUE, but sets it as setEnabled(false), why this
happens?

AjaxLazyLoadPanel not loading in IE
Hi, I have seen that AjaxLazyLoadPanel does not load in IE 9.0 with Wicket 1.5.3. What is insteresting, it does not load for me only at the first time after login. Scenario: lazy panels are placed on ListItems and after login they are constantly in loading state. When ListItems are replaced (so lazy panels are also created over again), lazy panels are loaded successfully. Wicket example at http://wicketstuff.org/wicket/ajax/lazy-loading?0 does not work either. I have found https://issues.apache.org/jira/browse/WICKET-4157 , could that be a regression? Another question: what are your (Wicket team) plans for Wicket 1.5.x and 6.0? Is 6.0 an experimental or do you plan in the future to focus on 6.0 as a base? Best regards Michal Wegrzyn

Subject: RE: abort loading lazy components
Thanks for an update Martin.
Unfortunately using IAjaxCallDecorator#decorateScript() prevents
handling request (nothing happens).
If I append the stop script directly to ajax request target (before
sending event), then request proceeds, but the first lazy component is
not loaded.
Also, the stop script breaks ajax indicators (both from lazy components
and indicating links). Exceptions still are present, but page isn't
crashing.
So far the closest solution was using BookmarkablePageLink, but it is
not ajax and it is just a workaround.
Isn't there a way to prevent Wicket from handling old ajax requests?
I assume that's how it should work with DROP channel.

It is triggered when there is already new itemList (it extends
DataView), so I suppose that
PageAndComponentProvider looks for itemList:29, which does not
exists
anymore.
Scenario:
- Page is loaded but lazy components
('folders:listContainer:itemList:itemPanel:folder:children') are
still
loading
- User triggers folder change (itemList is replaced)
- Exception occurs
If user triggers folder change when lazy components are completely
loaded (or during loading the last one) there is no exception at
all.

AjaxLazyLoadPanel changes
Hi, Is it possible to apply two changes for AjaxLazyLoadPanel (apache.wicket.extensions.ajax.markup.html.AjaxLazyLoadPanel)? - Can LAZY_LOAD_COMPONENT_ID be public? Sometimes id is needed beforehand. - AjaxLazyLoadPanel uses anonymous AbstractDefaultAjaxBehavior, so AjaxChannel cannot be easily overridden. Is it possible to introduce AjaxLazyLoadPanel#getChannel() ? Best regards, Michal Wegrzyn

RE: abort loading lazy components
Thanks for an update Martin.
Unfortunately using IAjaxCallDecorator#decorateScript() prevents handling
request (nothing happens).
If I append the stop script directly to ajax request target (before sending
event), then request proceeds, but the first lazy component is not loaded.
Also, the stop script breaks ajax indicators (both from lazy components and
indicating links). Exceptions still are present, but page isn't crashing.
So far the closest solution was using BookmarkablePageLink, but it is not ajax
and it is just a workaround.
Isn't there a way to prevent Wicket from handling old ajax requests? I assume
that's how it should work with DROP channel.
Best regards,
Michal Wegrzyn

It seems there is a way to simulate browser's stop button with
JavaScript.
Try to use that code from IAjaxCallDecorator#decorateScript() for your
AjaxLink.

It is triggered when there is already new itemList (it extends

RE: abort loading lazy components
Disabling request logger didn't help, however if this only a trace issue then it does not matter through.

abort loading lazy components
Hello, In application which I am developing AjaxLazyLoadPanel is used for several components. Wicket creates queue of synchronous Ajax requests for every lazy component. I saw several discussions about the way how Wicket loads the components (and AFAIK Wicket can do it only synchronously), but I could not find anything about canceling these requests. Now, even if user triggers new request, he still has to wait to load all lazy components. Then Wicket continues with request which was triggered during loading lazy components. Is there any way to cancel loading of the lazy components and handle new request immediately? Yours sincerely, Michal Wegrzyn
