Setting focus on textedit seems not working

Hello,

I'm quite new to openlaszlo. I've started a little program with 
login/password window. I want to have the cursor at the starting of the 
application focusing into the login textedit. This doesn't seem to be 
working with the piece of code I've writen (tested in firefox/swf9). 
Below is the source code. Doesn't anybody know why it doesn't work ?

Thanks !

<?xml version="1.0" encoding="UTF-8" ?>
<canvas id="Canvas" width="100%" height="100%" bgcolor="#EAEAEA" 
align="center" valign="middle">
    <handler name="oninit">
         Debug.debug('canvas init');
		lz.Focus.setFocus(LoginEdit.parent);
		Debug.debug(lz.Focus);
		Debug.inspect(lz.Focus.getFocus());
    </handler>
    <window id="LoginDlg" title="Welcome to Kanfous !" clickable="false" 
width="200" opacity="1" bgcolor="#EAEAEA" x="${(Canvas.width - 
LoginDlg.width) / 2}" y="${(Canvas.height - LoginDlg.height) / 2}">
         <handler name="oninit">
             Debug.debug('window init');
         	//this.animate('opacity',1,500,false);
         </handler>
    		<simplelayout axis="y" />
    		<view width="100%">
    		    <handler name="oninit">
             	Debug.debug('view init');
             </handler>

Dynamically Creating Attributes on distant objects

Hi all, I have a question that i've researched personally on LZX dynamic 
attribute creation and I couldn't find information on what I was trying 
to do. When i turn to the list, you can bet that it's an interesting 
question :)

I'm in a situation where i'd like to constrain (use the handler 
reference syntax) to some object's attribute even though that object 
*doesn't have that attribute declared on it originally*. Ideally at init 
time like to be able to enhance an object whose reference I happen to 
have with an attribute that has all of the characteristics of a normal 
attribute in terms of events and access.

I'm doing this to set up systems of timing where actions may be chained 
together, and requiring the programmer to manually place attributes on 
these action classes would be tedious and ugly. I'd like some "magic" here.

Any ideas? For those who are following, I'm trying to avoid the solution 
of hacking these attributes into lz node objects directly and globally, 
so I beg to turn to dynamism.

Any help or even vague and hazy impressions would be helpful! Thank you 
in advance,

.james robey.

Re: Setting focus on textedit seems not working

I'm using firefox 3.5.3 + openlaszlo-4.6.1-windows-dev-install.exe + 
debugger off + swf9.

I've checked again and it does work using dhtml but not in swf8/swf9. 
This is quite bad, because I've chosen openlaszlo to avoid javascript 
which I judge too slow compared to flash... Any idea why it doesn't work 
in flash mode ?

I think i might have answered my own question

     Poor form, sorry, but i answered my own question. I didn't need to 
do make another attribute. i found another way around the problem using 
these two lines which are a common pattern:

var something_method = new lz.Delegate(this, "something");
something_method.register(parent.after, "onmyevent");

     That worked just fine for my needs once i realized it was all i 
needed. Thanks for reading it!

Re: I think i might have answered my own question

You can do this in on operation:

new lz.Delegate(this, 'something', that, 'eventname');

you'll want to hang on to a reference to the new delegate, so you can  
unregister it in your destroy method, otherwise it causes a leak.

We hope to fix this some day:

http://jira.openlaszlo.org/jira/browse/LPP-225

Also, we have some ideas about how to dynamically add handlers, so  
that you don't have to understand the delegate mechanism to do what  
you want.  (Hm. can't find the Jira for tha just now...)

Happy birthday OpenLaszlo!

It's hard to believe we've been open source for 5 years.  I'll be 
hoisting a beer in honor of all our accomplishments and to all our 
wonderful contributors!  Happy birthday OpenLaszlo!

I wasn't very descriptive, sorry. Ideally i'd like to say

new lz.attribute(parent, {name:"somestate", type:"string", value:someval});

and have that work from that point on just as a normal attribute would. 
Am i missing a pattern that lets me do this clearly? It would be like 
annotations, i guess. and thanks for your response.
