Re: WebSocket Filter to open a Hibernate Session
Hi Martin, That's something I figured out as well, the bypassing of the Filters by WebSocket requests. I did as you said and implemented a custom IRquestCycleListener to respond on the onBeginRequest & onEndRequest in case there is a WebSocketRequest. This is working correctly now! Thanks for the pointer. One other question though, since this seems awfully similar to how OSIV works. If I do not filter on WebSocketRequest and allow the Session opening for each incoming request, in theory I should not need to apply the "OpenSessionInViewFilter" anymore correct? But then another thing I noticed... I set a debug point inside the onBeginRequest & onEndRequest to see what's is passing through those functions. Apparently for a single page request the onBeginRequest & onEndRequest are called multiple times while I have no Lazy Loading components on that page. My guess would be that those multiple requests are for the resources that needed to be loaded, e.g. images/js/css/whatever. In that respect, it would absolutely not be wise to use that to open & close hibernate sessions ;-) Upon a WebSocket event, the onBeginRequest & onEndRequest are called only once, so that's correct. Again thanks. Best Regards, Marco Springer On Tuesday 15 September 2015 18:06:51 Martin Grigorov wrote: > Hi, > > Servlet Filters are not used when sending messages in web socket > connection.

WebSocket Filter to open a Hibernate Session
Hi, Using normal requests and long-polling ajax timers to update an interface works fine with hibernate sessions. Now I'm trying to implement WebSockets to update small parts of a web application that come from server side events. I want to get rid of the long polling. For now I'm only using a @Scheduled annotation to broadcast an event to all attached clients. As a simple scenario. The web application should, in response, update with loading new data from a database using Hibernate. This is where it fails, giving the message: /Caused by: org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non- transactional one here/ I know this fails due to the fact that WebSocket events don't go through the normal filters, e.g. OpenSessionInViewFilter that I'm using. *My question:* Where can I create a hook where I can start the Hibernate Session the same way the OpenSessionInViewFilter does? If I'm totally off with my thoughts, I'd like to hear that too :) Used libraries: wicket 6.19.0 wicket-sprint 6.19.0 wicket-native-websocket-jetty9 6.19.0 hibernate 3.6.10-Final springframework 3.2.13-RELEASE (Why the old Hibernate/Spring versions: haven't had time to migrate yet, too much to do!) Thank you very much in advance. Best regards, Marco Springer
Re: NPE in AbstractSingleSelectChoice
Haven't run the code but my guess is that the idValue returns a null instead of 0. Take a look at AbstractSingleSelectChoice.convertChoiceIdToChoice(String) line 281. (Wicket 6.15.0) if(renderer.getIdValue(choice, index).equals(id) This would trigger a NPE if a null is returned, which would be the case with your nullItem.

Re: wicket resources with nginx as frontend proxy
Hi Martin,
Thank you for the suggestions.
I did manage to get the applications working together.
But... I'm not very sure if, what I am doing, is the correct way.
Therefor I created the minimal quickstart that does what I want it to do.
The quickstart is downloadable from:
http://www.glitchbox.nl/nginx_proxy.zip
It has a deployable war, the nginx.conf, the sources and a README that
describes what kind of requests the application should intercept.
Let me know if you need more information.

wicket

Requests to /wicket/** should be no different to the other requests.
But if you want to change the values of these special segments then see
Application#newMapperContext. This won't help you much IMO.

it looks to me like not finished *reverse* proxy config.
Wicket generates only relative urls and will not generate
http://someHost/unless you explicitly ask for a full url.

AuthenticatedWebApplication app = (AuthenticatedWebApplication)

Re: Detecting when nothing is added to AjaxRequestTarget
Hi Josh,
We also had that ComponentNotFoundException problem so now and
then.
My experience might be a different than yours but I'll mention it anyway,
you never know!.
From my experience with our clients, when the client has to wait a bit
longer, he/she re-clicks the same ajax link, where that ajax link will repaint
a panel when it's done processing whatever it has to do, causing the
button/link to disappear or entire panel disappear completely. The second
incoming request is then invalid for the current state of the page.
What I've done is override the updateAjaxAttributes function in the
AjaxLink/AjaxFallbackLink by the following:
/@Override/
/protected void updateAjaxAttributes(AjaxRequestAttributes attributes) {/
/ super.updateAjaxAttributes(attributes);/
/ attributes.setChannel(new AjaxChannel(blocking,
AjaxChannel.Type.ACTIVE));/
/}/
This makes sure that even though multiple AJAX requests are received,
only the first request is being processed, any following request is dropped.
Since I've applied this, I've seen no more ComponentNotFoundException.
Atleast not due to double-clicks/impatient clicks.
Rest of the wicketeers: is this bad practice? It's working very well for me
atm.
Cheers,
Marco

We get a lot of ComponentNotFoundExceptions in production and I have

this
and I think what is happening is that the user clicks something to
change
the state of the page, say it removes a button. If we don't add the panel
to the AjaxRequestTarget then the button will still be there on the
browser
for the user to click. When they click that button wicket throws this
exception because the server side does not find that button in the
component hierarchy(or it isn't visible or whatever).
So my question is how can I detect when an Ajax request happens and
nothing
gets added to the AjaxRequestTarget and log it out? Or is there a better
way
to run this down? I'm open to any ideas or strategies for fixing this
issue.
Thanks,

Re: Detecting when nothing is added to AjaxRequestTarget
That's great! For tabbed panels that take a while to load I just apply lazy loading panels, that way that tab gets loaded immediately and an indicator is shown that the panel is being loaded. The user knows that the panel is being loaded and is unable to click any links on the old panel. I handle it like how it's described here: http://www.mkyong.com/wicket/how-do-use-ajaxlazyloadpanel-in-wicket/ This also handles the scenario where non-JS enabled browser must be able to load the page (it's 2014 already, c'mon!).

We have a dashboard panel that has several tabs. Those tabs are ajax tabs. If a user clicks a tab and it takes a while to load then they click on a link on the current tab while waiting then you will get a ComponentNotFoundException. I tried to use the updateAjaxAttributes approach by making custom tab links, but that didn't work. Probably because the link they are clicking on the tab panel itself does not have that attribute. My simple solution to this is to just use a regular TabbedPanel instead of AjaxTabbedPanel. It seems to fix the issue.

That's what I use as well, depending on the scenario. Usually when there's a second modal window open, and closing that second modal requiring the first modal window to do a repaint on it's current content, I display a blocking layer, if the process takes longer than average (e.g. ~8 seconds).

Re: Draw inside Apache Wicket
Hi, I've used http://jsplumbtoolkit.com and intergrated that library into my wicket application without too much work. It also allows for partial updates or complete repaints depending on the HTML structure that's currently rendered in the browser. Of course it depends on the requirements but this library is pretty flexible in it's usage. I've created a MS Project/Gantt like interface with Wicket jsPlumb and it's working very well, even with larger data sets. And it has different render strategies, depending on the browser.

Re: 1.4 - 6.0 question
Hello Pierre,
You can also just override/extend the onComponentTag function from the
Component.:
Component {
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.put(attribute, value)
}
}
As far as I can see, SimpleAttributeModifier doesn't exist anymore, just use
the AttributeModifier class or sub-class that if you really need to.
Or attach a custom Behavior to the component which can also override the
onComponentTag function like so:
public class FeedbackFieldDecorator extends Behavior {
@Override
public void onComponentTag(Component component, ComponentTag tag) {
if (!((FormComponent?)component).isValid()) {
String cl = tag.getAttribute(class);
if (cl == null) {
tag.put(class, error);
} else {
tag.put(class, error + cl);
}
}
}
}
Cheers,
Marco

Adding a large amount of MarkupContainers into the ListView or RepeatingView
Hi,
Lets say I have about ~100.000 of MarkupContainer objects that I want to put
into a ListView or RepeatingView.
This works fine functional wise... It's rather slow though.
It boils down to:
MarkupContainer:
1309 private Component put(final Component child)
1310{
1311int index = children_indexOf(child);
1312if (index == -1)
1313{
1314children_add(child);
1315return null;
1316}
1317else
1318{
1319return children_set(index, child);
1320}
1321}
and the call to children_indexOf(child) where it loops over all it's
existing children and compares the id's until a match is found.
With an increasing amount of children this can get rather slow...
I though off overruling some functionality in the MarkupContainer class since
I'm sure that for this list of items the children will be unique in their id
and don't need that lookup, and overruling the put or children_indexOf
function would give me enough power to skip that performance impacting part.
But most functions have private access, leaving me nothing to control the
adding of child components to a MarkupContainer.
Does anyone else have experience with adding rather large quantities to
something like the ListView and/or RepeatingView?
Or is there another way of rendering this large amount of containers?
Thanks in advance.
Kind regards,
Marco
Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView
I'm building a Gantt like interface with Wicket (nearly finished). It was a requirement to see multiple years of planned items, in the extreme range even. I've down-tuned it to be around max ~3k (8 years) of components in that listview, through the power of persuasion and as a test. At 3k components, the getId() method is called quite a reasonable amount of times. around 4.5M'ish times through the children_indexOf method. But you're absolutely right, 100k components is bull. Right now I've settled with them that I'd change the view of the Gantt to be less detailed when that amount of data is in there. The UI is quite flexible in that I can change what I render. With 2 years, only 731 columns are rendered, each day is a column. When 2 years, I change the view to a more zoomed out version. With 8 years, only 97 columns are rendered, each month being a column. Etc... Still with all the components taken in as it is a Gantt chart kinda interface, the browsers that I test in are only getting a bit sluggish when I'm displaying around 2k of components on this Intel Q8200. I'm not displaying any fancy gif's/flash or whatever, only allot of div's and some svg overlays through jsPlumb for dependency display. I mainly found it staggering that the getId() function was called that much. As Martin said, I'm targeting to limit the amount of components that should be rendered now, although sometimes hard with this kind of interface. Cheers.

Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView
Hi Dan, Tnx for the suggestion. In the previous mail I mentioned to present a zoomed out version of the Gantt which is a logical view considering the display of several years, the detail of showing each day in those years is, well, useless. It was easy to change this, therefor not needing the sublisting and no architecture overhaul :). Again, I agree on keeping a lid on the amount of rendered components. Which I managed to do. On Tuesday 26 March 2013 10:52:53 Dan Retzlaff wrote: The javadoc for Component#put() refers to a now non-existent childForId map which got removed 8 years ago [1]! You might consider making your ListViewT into a ListViewListT and splitting the original dataset into say 10k List#subLists. It ain't pretty, but for a (nearly finished) app, it beats a serious architecture overhaul or waiting for a dubious change to wicket-core. Throw in some item.setRenderBodyOnly(true) and your markup will be none the wiser. :) [1] https://github.com/apache/wicket/commit/0a321ea04887a3113e183b46ab20c1c5d702 2de0#wicket/src/java/wicket/MarkupContainer.java On Tue, Mar 26, 2013 at 9:23 AM, Marco Springer ma...@glitchbox.nl wrote: I'm building a Gantt like interface with Wicket (nearly finished).

Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView
I've looked at Angular a while back and it certainly looks interesting. However I don't think it's wise to introduce another technology within the current company where I'm migrating a rather large CGI-BIN application to a Wicket variant and into several modules. I'm the main JAVA/Wicket guy now, the others are mainly C++ developers with some JAVA knowledge and growing in that knowledge as more and more parts are converted into Wicket counterparts. So they already have to get known with: Hibernate, parts of Spring, Wicket, Maven and HTML, CSS JS. Sooo for now.. I'm sticking with Wicket only. And with the zoomed out version and restricting the date range, ergo reducing the amount of components.., that fixes things. The future will give me plenty of time make things even fancier. Perhaps even the use of Angular. On Tuesday 26 March 2013 19:55:30 Ernesto Reinaldo Barreiro wrote: I mean: This same component could be used as context for AJAX interactions.

Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView
Actually, the performance problem was in the first row, well actually the
header that
was rendering all days in a week/month/year.
Each data row itself has a lot less items.
Each row has items that are absolutely positioned within the relatively
positioned row.
Each item can span over multiple days/week/months or even years, depending on
the
task duration.
Doing this instead of rendering divs for each day saves a lot of calculation on
the
server side and a whole lot less html on the client side.
And this creates other nifty possibilities like making the item divs resizable
and
draggable in that row with bound ajax calls to those actions.
For showing a grid I've done some background images that match the zoom level,
since each day is static in width.
I've thought about lazy loading the rows that where outside of the scrollable
view,
since I indeed have a scrollable view.
But that's something for the future.
Rendering the 287 years, e.g. 104k~ ish days, did render eventually and the
server
and browser didn't choke, but the div with was about 5M px width wide, so that
was
nonsense :P

WiQuery jquery UI version upgrade
Hi, I'm using the tooltip functionality from jQuery UI that has been introduced since version 1.9. To make that work I've done: addResourceReplacement(CoreUIJavaScriptResourceReference.get(), PxCoreUIJavaScriptResourceReference.get()); Which just includes the 1.10 version of jQuery and nothing seems to be broken so-far, with the WiQuery parts that I'm using. Is there a specific reason why WiQuery is using version 1.8 of the JQuery UI instead of the latest stable 1.10 series? Thanks in advance.

Wicket+Atmosphere behind Apache proxy problems
Hi all, I have the following scenario: A Jetty instance is running on port 8080 with URL: `http://localhost:8080/appl/test` The deployed Wicket application is using Atmosphere for push events. I've configured the Apache server as how it was explained on the following URL: https://github.com/Atmosphere/atmosphere/wiki/How-to-run-Atmosphere-behind-Apache-WebServer When I access `http://localhost:8080/appl/test` directly without the proxy, it's all working fine. As soon as I try it through the proxy, e.g. `http://localhost/appl/test`, weird stuff starts happening. Mostly I see that the function, that's annotated with the @Subscribe annotation, gets called multiple times, 4 to 12 times isn't uncommon. And it's almost always in a power 2. This doesn't happen without the proxy. The second browser instance that should receive the push event doesn't respond properly either. I get: `INFO: Response processed successfully. INFO: refocus last focused component not needed/allowed` Does anyone have some more knowledge about configuring Apache's proxy to allow for proper websocket/cometd push events through Atmosphere?

Re: Wicket+Atmosphere behind Apache proxy problems
I tinkered around and I did the following: init-param param-nameorg.atmosphere.useWebSocket/param-name param-valuefalse/param-value /init-param This forces the Atmosphere Framework to use the Jetty7CometSupport class instead of the Jetty8WebSocket class. Initially this looked.. fine. Except the rendered URL as a result of the push is invalid. Instead of it going to `/appl/test/`, it refers to `/test/`. Class `UrlRenderer` from the `org.apache.wicket.request` at line 258 prepends a .. segment to the finally rendered url. Which hints me that it tries to go one folder up the path... which seems wrong. The cause of this seems to be that there are 2 baseUrlSegments: appl test. Causing this .. to be added. I don't know why this is as it is, the Wicket developers must have some reason for this. All normal url's on the page render fine, except for the one(s) rendered after a push event through Jett7CometSupport. When Jett8WebSocket is used, the ./ is prepended to the URL, which is fine! So is this a bug in Wicket/Atmosphere or am I doing something wrong? Again, the quickstart is at http://www.glitchbox.nl/stack/atmosphere_proxy_problem.zip With the exception of the change in the web.xml as stated at the start of this mail.

Re: Error during start of wicket application
I'm using Intellij myself and with that, in the Project overview I see a list of dependencies projects are using. With that I can quickly see if I'm using multiple versions of a certain dependency. This same type of dependency list is present in Netbeans, only per project. And with Netbeans you can also generate a dependency graph by right clicking on your project, and this goes through all dependent projects and their deps as well. I have no deep experience with Eclipse, since I somehow dislike Eclipse with JAVA development, but I think it's available in there somewhere as well. I use those dependencies lists as well to find and clean up dependencies. Cheers, Marco Springer
Re: WiQuery disabling tabs
If anyone cares, I found a solution...
I'm guessing the previous solution isn't working because the statement is
probably output before the page is actually rendered.
Therefore i did the following:
tabs.add(new AbstractBehavior() {
@Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
StringBuilder js = new StringBuilder();
if (isNewObject) {
for (int i = 1; i 6; i++) {
js.append(tabs.disable(i).getStatement()).append(;);
}
}
response.renderOnDomReadyJavascript(js.toString());
}
});
If anyone thinks this is faulty or has a better solution, I'd like to know!
Kind regards,
Marco

*The question:*
I thought this would be a proper way to disable those tabs, apparently it
isn't.
If I call the disable function through ajax afterwards, like
disable(target, 1), it's fine.
Anyone an idea how you would disable a single (or multiple) tabs on the
first initial render?

I'm guessing the previous solution isn't working because the statement is
probably output before the page is actually rendered.
Therefore i did the following:
tabs.add(new AbstractBehavior() {
@Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
StringBuilder js = new StringBuilder();
if (isNewObject) {
for (int i = 1; i 6; i++) {
js.append(tabs.disable(i).getStatement()).append(;);
}
}
response.renderOnDomReadyJavascript(js.toString());
Move this line inside the if. No need to render empty JS.
}
});
If anyone thinks this is faulty or has a better solution, I'd like to
know!
Kind regards,

Hi all,

*The question:*
I thought this would be a proper way to disable those tabs, apparently
it
isn't.
If I call the disable function through ajax afterwards, like
disable(target, 1), it's fine.
Anyone an idea how you would disable a single (or multiple) tabs on the
first initial render?
Kind regards,
Marco

Re: WiQuery disabling tabs
Your suggestion:
if (((IModelWafer) getDefaultModel()).getObject().getId() == 0) {
ArrayItemOptionsIntegerItemOptions options = new
ArrayItemOptionsIntegerItemOptions();
for (int i = 1; i 6; i++) {
options.add(new IntegerItemOptions(i));
}
tabs.setDisabled(options);
}
My code sauce:
if (((IModelWafer) getDefaultModel()).getObject().getId() == 0) {
tabs.add(new AbstractBehavior() {
@Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
StringBuilder js = new StringBuilder();
for (int i = 1; i 6; i++) {
js.append(tabs.disable(i).getStatement()).append(;);
}
response.renderOnDomReadyJavascript(js.toString());
}
});
}
Yup I'm going for your suggestion.
Thanks Hielke.
Regards,
Marco

Yes I (and perhaps we) care. Unfortunately Google has decided that the

Fortunately most of the WiQuery committers are also on this mailinglist.
Any suggestions you have will be taken into account during our ever lasting
upgrade efforts for WiQuery.
Simply calling tab.disable(i); will not work as this function returns a
jQuery statement. If you do not use that nothing changes :S You should use
Tabs#setDisabled(ArrayItemOptionsIntegerItemOptions disabled). This will
disable all tabs that you specify upon first render. If you want to disable
any tab after first render you should use an ajax call and call
Tabs#disable(AjaxRequestTarget, int).
If there is a bug in WiQuery then please report it here:

Re: Authentication and sessions - the right way?
I sort of use the same thing, storing the user in the Session. Only I store a LoadableDetachableModel in the Session, representing the user. In my scenario, the LDM is a custom Model and the key identifier is a Long number, but that shouldn't be a difference. And the injection happens in the LDM as well. This works fine in both development deployment mode. And if any data is updated in the database, Hibernate is smart enough to detect the changes and serves the latest data from the database. If no changes occurred, a cache call is made.

Re: Authentication and sessions - the right way?
Each browser opens up a new session, that's no actual problem.
Sessions are pretty thread safe (correct me if I'm wrong) when they're
accessed from request threads (normal Wicket application flow).
If Browser #1 changes something to user data or some other db data, and
Browser #2 fires a new request, the data is instantly reloaded for that
Browser #2.
Though a problem would be if both instances submit the same type of data,
the last request performed is the one that's stored.
Although there are techniques to overcome this problem as well. Something
like:
http://docs.jboss.org/hibernate/core/3.5/reference/en/html/transactions.html#transactions-optimistic-manual
Some sample code (don't mind the fake names and I simplified the code to
just show the necessary):
public class CustomSessionT extends ModelObject extends WebSession {
private GenericDetachableModelT credentialLDM; // T as the user can be
of 2 object types in our situation
public static CustomSession get() {
return (CustomSession) Session.get();
}
public void setUser(GenericDetachableModelT credentialLDM) {
this.credentialLDM = credentialLDM;
}
public synchronized GenericDetachableModelT getUser() {
return credentialLDM;
}
}
And in the code where I need the user object I just make a call to:
CustomSession.get().getUser().getObject();
This will always retrieve the latest user instance in the database and is
valid during a complete Request.
And just as Martin said, put a memcache in between and the database
requests are minimized, if not already loaded from the Hibernate cache.
The LDM would be like:
public class GenericDetachableModelT extends ModelObject extends
LoadableDetachableModelT {
@SpringBean(name = service)
private Service service;
public GenericDetachableModel(T entity) {
this.entityId = entity.getId();
if (entity instanceof HibernateProxy) {
this.entityClass =
(Class) ((HibernateProxy)
entity).getHibernateLazyInitializer().getImplementation().getClass();
} else {
this.entityClass = (Class) entity.getClass();
}
InjectorHolder.getInjector().inject(this);
}
@Override
protected T load() {
return service.getObject(entityClass, entityId);
}
}
I do have some more session functionality to mingle with the user object,
but they are not important in this matter.

How does your code look then in session and how do you fetch your data?
Martin:
I was trying to save on costs, where on AppEngine you are billed for
every
DB query, while memcache is pretty much free. Is it really hard to keep
session data in sync? Only that user can modify his data.

Re: Apache Wicket Cookbook Published!
Just a general question about packthub... I've ordered the printed version on the 26th of March, from the Netherlands, but I haven't received it yet. Did someone else also order the printed version?

Re: Highlight current/clicked AjaxLink
Hi Mansour For reloading different pages I'm using BookmarkablePageLink (non-ajax), that have the option for setAutoEnable(true)'. When this option is set for each BookmarkablePageLink and one BookmarkablePageLink is clicked on the website, the generated HTML for that link is changed. For example: My current page is Home and the other available page link is the Gallery. spanemHome/em/span a href=galleryGallery/a After clicking on the Gallery button: a href=homeHome/a spanemGallery/em/span I think this does the job perfectly, in my case... Perhaps you can apply it for your case as well.
