Hi, Chris,
I tend to agree with you, that's why I prefer Java over Javascript.
However, I need to write a few components, so I'm wondering what
others do to help them avoid these types of errors that would normally
be caught at compile time.
Cheers,

Ok, this is fun. It was due to an error in my script.
I've been doing Java for so many years that I forgot how to use a
dynamic
language. I guess I'm too used to having the compiler tell me how
much
of
an idiot I am so I have less pain at runtime. ;-)
Humans aren't perfect - that's why humans invented typesafe languages!
:)
BTW, for you experts in js, is there any kind of compiler or
validator
or
something that you use to help locate errors? Or do you just play
around
with things at runtime? Or are you just smarter than me and don't
make
so
many typos?
Not wanting to start a flame war with the dynamic language
advocates...
Given the complexity of software development I find it amazing that
the
'non typesafe language' advocates are so willing to give up one of the
best 'error avoidance mechanims' known to the programming world over
the
last 3 decades.
Much better I find a bug at compile time than have it slip through
testing and then have customers find it at run time ...
But that's my personal opinion and others are free to have theirs'

Yeah it does seems as a problem.. what if you try putting in dummy
functions
with alerts in them?

Ok, thanks,
So, if it should be ok, I wonder why after the first execution, I
only
get
INFO: Channel busy - postponing...
So I can't use my component more than once...

Should be ok I guess, heres the definition of it, ..:
function wicketAjaxGet(url, successHandler, failureHandler,
precondition)

I should add that in my onCloseHandler, I have this in my js:
$('#popup #popup-close-link').click(function (e)
{
e.preventDefault();
$('#popup-mask, #popup-window').hide();
if( url != "" )
wicketAjaxGet(url, null, null, null);
});
As far as I can tell, this seems to be the correct use of
wicketAjaxGet...

Hello, Wicketeers,
I have a link that is supposed to call a JQuery component called
"popup".
final AjaxLink<Void> popupLink = new
AjaxLink<Void>( "link.popup"
)
{
@Override
public void onClick( AjaxRequestTarget target )
{
target.addComponent( popup );
final StringBuilder s = new StringBuilder();
s.append( "$.fn.popup({" )
.append( "url: \"" ).append(
onCloseBehavior.getCallbackUrl()
).append( "\"" )
.append( "});" );
target.appendJavascript( s.toString() );
}
};
Works just fine the first time, but each subsequent call, I can
see
the
following message in the Ajax Debug Window:
INFO: Channel busy - postponing...
Other than the link above, nothing else is going on!
Do I need to somehow close the channel, or something?
Thanks!
