Re: Wicket for large user base website

read https://cwiki.apache.org/confluence/x/qIaoAQ to understand how
Wicket stores the pages

the app I work on has ~15M registered users and ~200K concurrent
users. I hope these are good enough numbers for you

Re: Error with link in DataTable together with AjaxEventBehavior("onclick")

2012-05-07 Thread Martin Grigorov
Hi,

This is how the event propagation/bubbling works in the browsers.
You need to suppress the bubbling of the JavaScript event.
See http://www.quirksmode.org/js/events_order.html for more info.
You can use IAjaxCallDecorator to stop the event after clicking on the
ajax link.

You can register 'postCallHandler' and/or 'failureHandler' and this

Re: Exception when detaching/serializing a page

2012-05-07 Thread Martin Grigorov
Hi,

This error means that for some reason the page instance cannot be
stored in the disk.
Any following Ajax request would not be able to find the page instance
and thus wont work (e.g. the ModalWindow uses Ajax).
I'd recommend to enable finer logging for Session class and see what
is the real cause of this problem.

refresh page from an AjaxLink or OnChangeAjaxBehavior

2012-05-07 Thread Mihai Toma
Hi,

 

I have an OnChangeAjaxBehavior on a DropDownChoice component.

 

After I change a value in that drop down I want to reload the page using
setResponse(currentPage.getClass(), currentPage.getPageParameters());

 

themeComp.add(new OnChangeAjaxBehavior() {

private static final long
serialVersionUID = -1973825163343103968L;

 

@Override

protected void
onUpdate(final AjaxRequestTarget arg0) {

 
setAValueInSession();

setResponse(currentPage.getClass(), currentPage.getPageParameters());

}

});

 

The response from ajax debug is "ERROR: Wicket.Ajax.Call.failure: Error
while parsing response: Could not find root  element". I
receive the content from ajax but it is not between  element.

 

I verify this problem on AjaxLink and the response is the same as from
OnChangeAjaxBehavior.

 

Do you have any idea how to reload the page from an AjaxLink or
OnChangeAjaxBehavior ?

 

Thanks,

Mihai

Wicket Examples

The wicket examples (www.wicket-library.com/wicket-examples/) seems to be 
having issues.

I select the Contacts Editor option under the repeaters section and I get a 
permgen error.

Is this site working properly?  I assume the URL above is appropriate?

Re: Wicket for large user base website

2012-05-07 Thread kshitiz
Thanks all for the reply...actually I haven't looked into the hardware as I
am in middle of application development. Just going through various forums,
people were recommending Wicket for dekstop apps as it is statefull
framework. But as I can see various Wicket websites with high traffic, I
think there is nothing to worry about. Also, memory efficiency can be
achieved by making some pages stateless.

Append wicketAjaxget() after some javascripts

2012-05-07 Thread jiayang
Hi, I want to clear the focused text fields by using java script instead of
through wicket. Thus, I want the onfocus="this.value=' '; var
wcall=wicketAjaxGet(url,function, function,function);  " Is there any way to
implement this? 
Since there are several text fields with different Url, I can't hard code a
function called callWicket() for all the fields.
