Thanks for the pointers, Max. I start in on it, but I have a few
questions
It looks like I should just copy the code (snippet below) into the
applet_tag defeinition, parameterizing "lzapp" and the other params.
* How do I pass in vars?
* Does it use swfobject underneath or have its own auto-install Flash
stuff in it?
* swfobject has a nice feature where you name a div where you want it
to go and if there is no Flash it will display whatever is in that
div... is there anything like that built in? If not, I'll add that to
my list.
<script type="text/javascript" src="/trunk/lps/includes/embed-
compressed.js"></script>
<script type="text/javascript">
lz.embed.swf({url: 'copy-of-hello.lzx?lzt=swf',
allowfullscreen: 'false', bgcolor: '#ffffff', width: '100%', height:
'100%', id: 'lzapp', accessible: 'false'});
</script>

I'm a little busy working on my talk now, but I should have more
time in a few days. I can help you if you get stuck, but in the
mean time you may want to check out the templates here:
http://svn.openlaszlo.org/openlaszlo/trunk/WEB-INF/lps/templates/html-response.xslt
You can also look at the generated HTML for your app with lzt=html.
Did you get the automatic dataset/model synchronization working
again? If so, very cool!

Any interest in collaborating on how to add that to
openlaszlo_plugin for rails? or give me a hint as to where to
start? (oddly I know next to nothing about the lz.embed code and
how to integrate it onto a page of my own... must be in the dguide
somewhere, I suppose)
I got the tests working in the lastest rails (and older 2.x should
work too) and added a bunch of tests for the applet and swfobject
tags. Oliver hasn't pulled yet, so the latest is at:

Yes, you will need the lz.embed stuff. It has lots of other
benefits, like history and mousewheel support.

Can I just declare a method on the canvas and call it with:
value =
lz.embed.lzapp.callMethod('globalreference.canvas.anyMethod(...)')
Also, do I need all the lz embed stuff to do this? I was just
using swfobject_tag in rails... and then I would just call the
method on the object in javascript.

It just means you need a top-level instance with an ID. You can

What does this mean: "You can call any available method in the

Do I need to define "globalreference" in a script tag?
Thanks,

Yes! See the docs for any app with lzt=deployment, e.g.:
http://labs.openlaszlo.org/trunk-nightly/my-apps/copy-of-hello.lzx?lzt=deployment
To call a method in an application, use:
value =
lz
.embed
.lzapp.callMethod('globalreference.reference.anyMethod(...)')
passing a string representation of the method and any
arguments you wish to pass. You can call any available method
in the application as long as 'globalreference' can be found
in the global scope.
To call a method in all applications on the page, use:
lz.embed.callMethod('globalreference.reference.anyMethod(...)')

So, is there any native-LZX way to do this? or is the Flash
API the best I can do for now?
Thanks!

You're looking at out of date docs, the new docs say it has

addCallback () method
| public static function addCallback(functionName:String <http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/String.html
>, closure:Function <http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/Function.html

* Language Version : * ActionScript 3.0
* Runtime Versions : * AIR 1.0, Flash Player 9
Registers an ActionScript method as callable from the
container. After a successful invocation of |addCallBack()|,
the registered function in Flash Player can be called by
JavaScript or ActiveX code in the container.
*Note:* For /local/ content running in a browser, calls to
the |ExternalInterface.addCallback()| method work only if
the SWF file and the containing web page are in the local-
trusted security sandbox. For more information, see the
following:
* The security chapter
<http://www.adobe.com/go/flashCS3_progAS3_security> in the
/Programming ActionScript 3.0/ book and the latest
comments on
LiveDocs
* The Flash Player 9 Security white paper
<http://www.adobe.com/go/fp9_0_security>
Parameters
|functionName:String <http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/String.html
>| — The name by which the container can invoke the function.
|closure:Function <http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/Function.html
>| — The function closure to invoke. This could be a free-
standing function, or it could be a method closure
referencing a method of an object instance. By passing a
method closure, you can direct the callback at a method of a
particular object instance.
Throws
|Error <http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/Error.html
> | — The container does not support incoming calls.
Incoming calls are supported only in Internet Explorer for
Windows and browsers that use the NPRuntime API such as
Mozilla 1.7.5 and later or Firefox 1.0 and later.
|SecurityError <http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/SecurityError.html
> | — A callback with the specified name has already been
added by ActionScript in a sandbox to which you do not have
access; you cannot overwrite that callback. To work around
this problem, rewrite the ActionScript that originally
called the |addCallback()| method so that it also calls the |
Security.allowDomain()| method.
|SecurityError <http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/SecurityError.html
> | — The containing environment belongs to a security
sandbox to which the calling code does not have access. To
fix this problem, follow these steps:
1. In the |object| tag for the SWF file in the containing HTML
page, set the following parameter:
|<param name="allowScriptAccess" value="always" />|
2. In the SWF file, add the following ActionScript:
|flash.system.Security.allowDomain(/sourceDomain/)|

The Flash docs indicate that there are three arguments:

Also, is there any LZX-native way that I should be making this
call instead of devolving into calling Flash directly?
