Re: aj Component twice in markup while ax refresh in Wicket 6.7 (migrated from 1.5.10)
I followed Martin's hint and with wicket 6.7.0 I manually changed the
replacement in the javascript from
jQuery(element).after($newElement).remove();
to
jQuery(element).replaceWith($newElement);
But I just saw, that in Github
(https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/ajax/res/js/wicket-ajax-jquery.js#L1617)
replaceWith is now the standard replacement.
Will this appear in Wicket 6.9.0?

Hi,
we had similar issue and could not find jira ticket for this, thus created

Our workaround was changing our jQuery('#someid').. to
jQuery('[id=someid]').. to match all same (two) ids.

thanks for you quick replies! I will create the quick start and attach it

Thanks to your hint Martin, for the moment I will use jQuery#replaceWith()

So yes, there is a small period when both the old and the new are in

Re: Persistence.xml problem
I can assure you that there are no apparent problems/conflicts in using EclipseLink alongside Wicket. I'm doing it constantly :) It is likely that there is an issue with how your IDE is setup or packages the files. Some tools write their own META-INF directory in a war instead of using the one designated in your sources. That may need some tweaking but it's a stab in the dark since my setup is a Maven/Eclipse combo, so I cannot help on IDE specific issues. The principle remains the same though. It may be worth looking at the actual war archive and see whether the persistence.xml file is actually included at the right spot. Try changing the persistence unit's name and see whether the new name is recognised when you instantiate your PersistenceManagerFactory.

Re: Scalability
I've had excellent results with Glassfish. The login server for the MMO I worked on (swtor.com) has been benchmarked at 32,000 logins per second on a 8 CPU machine. The maximum throughput on a simple servlet (nothing dynamic though, just static data), was benchmarked at around 70k. Obviously, obtaining these rates depends on a lot of things, and we noticed that (unsurprisingly) the number of cores has a big impact on maximum scalability (32 / 8 = 4k per core). If you use an antiquated server that still processes requests on a thread per connection model, then your throughput will suffer dramatically. Any modern app server or webserver that has a good non-blocking I/O implementation of the reqest/response handler will do. Servers that come to my mind are tomcat 6, glassfish, grizzly... Hope this helps happy hacking!

Re: i18n feedbackmessages
Thanks, Johan
With that code you are adding an attribute modifier ever time the button renders
And you did get an exception i guess because you call getString() out of the
blue inside a construtor of a not fully constructed class.
thats why i moved the code to the propably wrong place..
To do that you have to lazy get the string through a model.getObject().
Then also a language change will result that the button will be translated on
the fly
i have implemented the class I18NAttributeModifier which does what you
proposed, by peeking
at the SimpleAttributeModifier code;
private class I18NAttributeModifier extends AbstractBehavior {
private String attribute;
private String value;
public I18NAttributeModifier(String attribute, String value) {
this.attribute = attribute;
this.value = value;
}
/**
* @see
org.apache.wicket.behavior.AbstractBehavior#onComponentTag(org.apache.wicket.Component,
* org.apache.wicket.markup.ComponentTag)
*/
public void onComponentTag(final Component component, final
ComponentTag tag)
{
if (isEnabled(component))
{
tag.getAttributes().put(attribute, getString(value));
}
}
}
this modifier is added in the constructor and is a private class to the
Form i extended from WebPage
which is why the getString() method is available.
however i find this a little bit like a quick fix. how should i modify the
class to be reusable from other forms with a button?
if i also try to keep the localizer in the internal class by calling
getLocalizer() in the constructor of the Form class, and replace
the getString() by localizer.getString() in the onComponentTag event
to be able to externalize I18NAttributeModifier for more common usage,
the resource string is not found - probably because the localizer was
overwritten after my code getting it in the ctor.
it's a pity that the button needs to be handled in a special way,
is there maybe a way to improve this, or am i doing something wrong?
thanks, regards
nico
