Re: org.apache.wicket.protocol.http.WebSession cannot be cast to my.CustomSession
I switched over to using an anonymous overridden WebApplication:
--
WebApplication webApplication = new WebApplication() {
@Override
public Session newSession(Request request, Response response) {
return new CustomSession(request);
}
@Override
public Class getHomePage() {
return null;
}
};
WicketTester tester = new WicketTester(webApplication);
--
This way I got my CustomSession (bye bye CCE) and a valid non-spring
WebApplication. I'm curious about what problems I'm going to have with that.
:)
Thanks everyone for your efforts and savvy!

Re: AjaxEditableLabel in 1.3.0
This is very odd, I just tested with a clean 1.3.1-based build of my test app. It works fine on one machine but not on the other!

Re: wicketstuff-rome and authentification.
My feed was a shared resource just like the wicketstuff-rome example.

Wicket uses them too. I have absolutely no clue how wicketstuff-rome or rss for that matter works but it looks like they are using a regular wicket page. So the question is what do you want? i can think of the following solutions, but there are probably some more i haven't thought of -do the authentication on the fly in your page (you do not need any fancy security framework for this) -put a filter in front of your app that does the validation for the rss feed for you (you do not need any fancy security framework for this) -you can secure the page in the recommended way of your security framework (wicket-auth roles or swarm) whichever you prefer depends on a couple of things -are you already using a wicket security-framework? or something like acegi? -is it enough for you to authenticate the user or does he need extra permissions to access the feed? -do you prefer keeping everything in wicket or are you ok with servletfilters and stuff? So you see there is no right or wrong direction, all roads lead to rome (pun intended) Let me know what you prefer and we go from there.

comunication between panels
i have a question: how can i comunicate between panels in wicket?
my application contains a frameset of 2 pages, each of these has a
tabbedPanel containing many panels:
structure--
APP
PAGE1 PAG2
panel panel panelpanel panel panel
---
what is a good solution?
MY solution is to:
1)extends WicketSession and implements get/set methods to retrieve insances
of these panels
2)use it:
Panel donald = ( (MySession) panel.getSession() ).getPanel('donaldduck');
so i can retrieve insance of foo panel everywhere and use its public
methods.
IS A CORRECT SOLUTION?
and then... PUTTING PANELS INSTANCES IN SESSION is a bad implementation
about MEMORY AND wicket SERIALIZATION ?
There is a BEST SOLUTION? that i don't know
Thanks.

Re: comunication between panels
panels in session is a bad idea.
Why not just keep the panel state information in the session and then let
them just pull it from there when they instantiate?
By the way, what are you trying to achieve with your panels cuz it is a bad
idea to be stuffing up panels in your session when you can simply keep the
state information the panels need there.
If you instantiate a new Panel, the new Panel can call
getSession().getInformationStateId(), pass that informationState to an
IModel and then the Panel has whatever it needs

Re: comunication between panels
Panel A puts the state information in the session during Link.onClick()
Panel B uses Session.getSession() to retrieve the state information during
render()
this simple technique is what i use and its very efficient.

The normal Wicket way is to share models, pass references etc,
but it has its limitations.
You can find an example of a push-type mechanism here
https://issues.apache.org/jira/browse/WICKET-1312
though it is done with just one page in mind.
MY solution is to:
1)extends WicketSession and implements get/set methods to retrieve insances
of these panels
2)use it:
Panel donald = ( (MySession) panel.getSession() ).getPanel('donaldduck');
This seems strage to me, I wouldn't put Components to Session.
You might want to step back to think about what it is that
you want to achieve, and maybe post here about the more
general issue. Maybe there is a better solution for your
real case than the panels of different pages communicating
between each other.
There is a BEST SOLUTION? that i don't know
No :)

self refreshing table with effects
Hi, I am new to Wicket and I think of how to achieve the following: I need a table which refreshes itself every 5 sec. This could be done with AjaxSelfUpdatingTimerBehavior. The refresh mechanismen shall only insert new rows at the beginning (there will be always only 1 new row in a 5 sec period). The table shall only display 10 rows (or be configurable), so if a new row comes in the 10th row should dispear. The new row can have several effects like sliding in, flashing ... I need this as monitoring component. Has anyone done something like this? Any suggestions are welcome, maybe it is obvious?

AJAX validation and multiple requests
Hi everyone!
I'm having a little problem..
I have an Ajax editable table made with rows of custom components similar to
AjaxEditableLabel, that while in edit mode use a behavior like this one:
protected class EditorBehavior extends AbstractDefaultAjaxBehavior{
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
String js={wicketAjaxGet(' + getCallbackUrl() +
'+this.name+'='+wicketEncode(this.value)); return false;};
tag.put(onblur, js);
}
@Override
protected void respond(AjaxRequestTarget target) {
FormComponent c = (FormComponent) getEditorComponent();
c.processInput();
if(c.hasErrorMessage()){
Serializable msg = c.getFeedbackMessage().getMessage();
Util.showAlert(target, c, msg.toString());
}
}
}
(Util.showAlert adds to the component a behavior that shows an alert)
Everything works fine, but I need to add another behavior to intercept when the
user presses Enter (bound to onkeyup), so that I can validate the row as a
whole.
When I press enter, two requests are fired: one for onblur and one for onkeyup.
My problem is that even if the onblur request finds an error during validation
(and shows the corresponding alert), the second request has no way to know
that, since feedback messages are cleaned up at the end of each request..
Any hint on how I could handle this? Should I put a flag somewhere? Or maybe
there's a way to stop the second request when my EditorBehavior finds a
validation error?
Many thanks for your time!

Re: IDataProvider and Hibernate Search
You could keep an instance of the search results in the dataprovider.
Then on size() and iterator() check to see if results is null. If it
is perform the query and store the results
ie:
add this to your searchdataprovider
private transient SearchResults results;
private void searchIfNecessary() {
//if(results!=null) return;
//get results
}
public int size() {
searchIfNecessary();
return results.getTotal();
}

Hello,
I want to use DataView to present Search Results from Hibernate
Search, but I got stuck with implementation of DataProvider - maybe
first I show you classes:
private class SearchDataProvider implements IDataProvider {
private String query;
public SearchDataProvider(String query) {
this.query = query;
}
@Override
public Iterator iterator(int first, int count) {
SearchDAO.SearchResults searchedAdverts =
searchDAO.getSearchedAdverts(this.query, first, count);
return searchedAdverts.getResults().iterator();
}
@Override
public IModel model(Object object) {
return new Model((Advertisement) object);
}
@Override
public int size() {
SearchDAO.SearchResults searchedAdverts =
searchDAO.getSearchedAdverts(this.query, 0, 0);
return searchedAdverts.getCount();
}
@Override
public void detach() {
}
}
in SearchDAO I have:
public class SearchDAO extends HibernateDaoSupport {
public SearchResults getSearchedAdverts(final String queryString, int
first, int count) {
Session session = getSession(true);
FullTextSession fullTextSession =
Search.createFullTextSession(session);
SearchResults results = null;
Transaction tx = fullTextSession.beginTransaction();
MultiFieldQueryParser parser = new MultiFieldQueryParser( new
String[]{title, rawBody},
new StandardAnalyzer());
Query query;
try {
query = parser.parse(queryString);
FullTextQuery hibQuery =
fullTextSession.createFullTextQuery(query,
Advertisement.class)
.setFirstResult(first)
.setMaxResults(count);
results = new SearchResults(hibQuery.list(),
hibQuery.getResultSize());
} catch (ParseException e) {
e.printStackTrace();
} finally {
tx.commit();
session.close();
}
}
SearchResults is a wrapper for sublist of results and number of all:
public class SearchResults {
private ListAdvertisement results = null;
private int count = 0;
public SearchResults(ListAdvertisement results, int count) {
super();
this.results = results;
this.count = count;
}
//getters/setters
}
As you see I have to repeat searching in size() and iterator()
(SearchDAO.SearchResults searchedAdverts =
searchDAO.getSearchedAdverts(this.query, 0, 0); and
SearchDAO.SearchResults searchedAdverts =
searchDAO.getSearchedAdverts(this.query, first, count);) in size I do
not get collection, but searching happens because this method is
launched before iterator() which could answer with number of all
results as hibQuery.getResultSize();
It's very inefficient, and I don't know how can I repair that, without
writing my own DataView implementation. DataProvider is good for
databases which need to make additional select count(*), but Lucene
Hibernate Search make it in one pass.
Anybody has a suggestion on this topic?
Best regards,
Adr

Then on size() and iterator() check to see if results is null. If it is perform the query and store the results Yes, I tried this before and I won't work because of querying size() before iterator() - to get results I need to know what is first result and how many of them to fetch, I don't know this in DataProvider because some other class (DataView?) manage the values provided to iterator (first and count). As I said size() is used BEFORE iterator() so size has to ask for results first, as I don't know where I am in result set (eg. I don't know getCurrentPage() for DataView), I cannot in size() ask for eg. SearchDAO.SearchResults searchedAdverts = searchDAO.getSearchedAdverts(this.query, 40, 20); As I would know or can pass getCurrentPage() to the DataProvider constructor I could fetch the result set in size() method and put them into field of SearchDataProvider. Maybe I should explain how Hibernate Search works here - when asking DAO for results first search is asked and it returns all the docsId which next are sliced based on first, count parameters - next same engine ask database for objects eg form Advertisement a where a.id in (1,23,45,67,77) - in one pass I can get 20 objects from whole results set and the exact number of documents which are proper for search criteria.

Re: IDataProvider and Hibernate Search
Finally I got it - I use such DataProvider:
private class SearchDataProvider implements IDataProvider {
private String query;
private int resultsPerPage;
private SearchDAO.SearchResults searchedAdverts;
private Integer resultsCount;
public SearchDataProvider(String query, int resultsPerPage) {
this.query = query;
this.resultsPerPage = resultsPerPage;
}
public Iterator iterator(int first, int count) {
if(searchedAdverts == null) {
searchedAdverts =
searchDAO.getSearchedAdverts(this.query, first, count);
}
return searchedAdverts.getResults().iterator();
}
public IModel model(Object object) {
return new Model((Advertisement) object);
}
public int size() {
if(resultsCount == null) {
searchedAdverts =
searchDAO.getSearchedAdverts(this.query, 0,
this.resultsPerPage);
resultsCount = searchedAdverts.getCount();
}
return resultsCount;
}
public void detach() {
searchedAdverts = null;
}
}
Transient doesn't work in my case, but setting null on object in
detach() makes what transient should. Size is asked only once for a
search, and number of results is set as Integer (also could be added
to iterator if some results appear in time of walking thru the search
results), iterators() if size is known also would be queried once -
this is what should be done.

Adr

Re: Exception redirecting to source page
good. there are some internals that do not count on a runtime
exception being thrown because of user code...for example throwing it
out of something like validator will abort entire form processing, and
might leave that particular form component in an inconsistent state.
but throwing it out of onclick/onsubmit handlers shouldnt pose much
problem as most wicket processing has already happened.

Re: AJAX validation and multiple requests
one way would be to keep a boolean somewhere that marks if the
component is valid or not...but if i were you i would figure out why
the two requests are fired and how to avoid it. can it be that your
enter key handler does not return false as the last thing and so
doesnt cancel browser's processing of enter key?

[wicket-spring] Best Practices...
If I want to use wicket-spring, but I want to try to let Spring wire everything together, what is the best way to do so? I realize that there is the SpringWebApplicationFactory class, but that merely looks up the application in the Spring context. The WebApplication class isn't very beany though (and it's abstract, so I have to subclass it no matter what). It doesn't have setters for stuff like the pageSettings or applicationSettings properties. The Application (the parent of WebApplication) class defines an instance variable of type Settings which covers most of this stuff. The getters for applicationSettings and pageSettings merely return getSettings(). Of course getSettings() is private, so I can't override that unfortunately. Anyway, what I want is for the wicket classes to be more bean-oriented so that I can piece them together how I see fit, by overriding certain properties (like AuthorizationStrategy) and leaving the defaults for others. Has anyone done this before? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Error handling for RuntimeExceptions during page construction
It depends on the deployment setting what you will see. Take a look at the wicket in action examples (http://wicketinaction.googlecode.com), currently chapter 15 (soon to become chapter 14).
