Sorry, yesterday there was too muc todo for the customers. Here we go:
On Sunday I have installed IEs4Linux on m Linux machine with IE5, IE5.5, IE6
and IE7 all of them except for IE5 worked correctly. Now I have tested on a
Windows XP machine with IE7. I have no problems with a relative package path
('packages/'), but an absolute package path to a network device
('//server/share/test/chili/packages/') doesn't work.

I tried your code with Firefox 2.0, Opera 9.02 and Konqueror 3.5.5 on Linux. Firefox is OK, Opera has huge linespaces, but shows the colors. Konqueror doesn't do any coloring at all, but an alert() in the calback of $using() in chili.js fires. I guess you have tried that alert with IE as well.

Since you don't load chili.js via jsPax you don't necessarily need the
$package()-call, but it doesn't hurt.
> 3.I've changed the default path inside package.js to:
> $package.packageBase = 'packages/';
Just a guess: Have you tried to use an absolute URL, or at leas an absolute
path here? Maybe Firefox interprets that relative to the current HTML page
and IE interprets it relative to the js. Then IE tries to
load "packages/packages/jquery.js" where Firefox loads "packages/jquery.js".
> 6.It works in FF, but it does not in IE.
I can not see anything you have done wrong.
If my guess proves to be correct I will change the documentation accordingly
and think abuout what I can do about it. In all Tests I did, I have used
absolute paths ("/test/packages/") or even absolute URLs
("http://www.example.com/test/packages/";), or I have the script that calls
$using() in the same directory as the HTML or even embedded into the HTML
(like the testsuite). Therefore I did not come accross that problem.

Re: [jQuery] dynamic loading of jquery.js into my web page
1. I've put this line at the bottom of the standard jquery.js file not
compressed:
$package('jquery',{});
2. I've wrapped the content of the standard chili.js file inside this:
$using( 'jquery', function() {
...
} );
3. I've changed the default path inside package.js to:
$package.packageBase = 'packages/';
4. I've added this markup to mypage.html:
5. I've put the modified chili.js and jquery.js files inside the 'packages'
folder,
so the folder from where the page is loaded contains: mypage.html,
package.js, packages/
6. It works in FF, but it does not in IE.

It doesn't. script2 is not downloaded at all, it is like a inline script. As
you might know scripts are evaluated in the order they are in the HTML code,
that is that script will be evaluated before script2 is.
It does work in all browsers I have tested jsPax with. The only problem I know
of is that script2 will also be evaluated if script can not be loaded
sucessfully. Then as soon as the browser knows that it can not load script,
it evaluates script2.

I have a simple line at the end of jquery.js:
$package('jquery',{});
The plugins are wraped with
$using('jquery', function() {
...
$package('jquery.myplugin',{});
});
If I then decide, I need the foo- and the bar-plugin in my code I simply do
$using(['jquery.foo','jquery.bar'], function() {
alert('jquery and foo plugin are loaded now');
});
That way I load much of the needed functions on demand. Which reduces startup
time - paied with eventual delays at the first use of some functions.

That looks really dodgy, sorry.
What if the browser downloads script and script2 at the same time, and
script2 finishes first?
Instead, simply edit your copy of jquery.js and add one like of code at the
end of the file, to call a "ready" function that you've defined in your
already-running code. If you have jQuery plugins that your code depends on,
merge them all into jquery.js and add that function call at the very end.
Hmm... This would make a nice patch for jQuery itself - when it concatenates
all the files to make the various "dist" versions, add this line to the end
of the merged code:
window.jQuery_onload && jQuery_onload();
John et al, what do you think?

Then your solution is almost OK for you. Here is a usable version ;-)
(function() {
var addScriptCounter = 0;
function addScript( url, callback ) {
var script = document.createElement( 'script' );
script.myLoadHandler = callback;
script.id = 'dynamicallyLoadedScript_'+addScriptCounter;
script.type = 'text/javascript';
script.charset = 'utf-8';
script.src = url;
var script2 = document.createElement( 'script' );
script2.type = 'text/javascript';
script2.charset = 'utf-8';
script2.appendChild(
document.createTextNode(
'(function(){'+
'document.getElementById(\'dynamicallyLoadedScript_'+
addScriptCounter+'\').myLoadHandler();})()';
));
var head = document.getElementsByTagName('head')[0];
head.appendChild( script );
head.appendChild( script2 );
addScriptCounter++;
}
})()
Usage:
addScript('jquery.js', function() {
alert('horay, jQuery is available');
});
alert('jQuery is not necessarily available here');
The second script tag will be evaluated after the first one has been loaded
and evaluated. At least that works for all browsers I have tested with,
except those Safari versions and very old browsers without a usable DOM
implementation.
If jQuery cannot be loaded successfully (wrong url e.g.), your callback will
still be called, and will fail as soon as it tries to access jQuery.
If you use a XMLHttpRequest, you can distinguish the case when loading was not
successfull from successfull loading before you really call the callback. By
the way you also get it working for Safari, but keep out those browsers
without a XMLHttpRequest implementation. For them jsPax falls back to adding
script tags via DOM.
That does not work only for the very old browsers without a usable DOM
implementation. There is also a fallback for them in jsPax, but I have not
really tested it, because I don't have such a browser at hand - theoretically
it should work.

Re: [jQuery] dynamic loading of jquery.js into my web page
Christof,
I'm afraid that I simply don't take Safari users into account. Hardly a
great thing, but I focus on three browsers: Firefox and IE7, and then IE6.
In that order. The work I do is targetted at corporate users who run Windows
2000 and Firefox, and all the JS work I do is for those users. About three
people in our company have a Mac, and all of them use FF, so Safari simply
doesn't come into my considerations when coding.
Thanks though. It's always good to know a browsers limitations. :-)
Cheers,
Dan

There are safari-versions which don't eval scripts like that. That is the
reason, why jspax uses XMLHttpRequest and eval() if possible and inserts a
script tag if XMLHttpRequest is not available (that deffinatelly is not that
Safari version then).
> addScript('jquery.js');
And then you guess the time when jquery is loaded. You can not expect that
jQuery is available when addScript returns. With jsPax you use
$using('jquery',function() {
alert('jQuery is now available');
});

Yes, and we had the problem with Safari in almost every thread about this
issue. We also had the problem of knowing the moment, the script has been
loaded almost in every one of those threads.
Sorry Dan, but I thought you really should have come across those issues.

Re: [jQuery] dynamic loading of jquery.js into my web page
function addScript( url ) {
var script = document.createElement( 'script' );
script.type = 'text/javascript';
script.charset = 'utf-8';
script.src = url;
document.getElementsByTagName('head')[0].appendChild( script );
};
You would use it by doing something like:
addScript('jquery.js');
I would recommend doing a search on the Nabble mailing list page for this,
as it has been covered many times before.
