Yeah, I think I can implement that without much trouble, and I can see that 
being a nice way to handle uploads in forms.

Re: File Upload

[Mike Schrag]

One thing that would be nice is a javascript function to start the upload and a 
callback on completion ... This would potentially allow a solution to file 
uploads in ajax forms -- you could have a "submit button" that when clicked, 
grayed out the submit ("sending..."), starts the upload in the form, and on 
completion, it could then actually perform the ajax submit of the rest of the 
form.

File Upload

[David LeBer]

Hey all,

Because of the way inline edit pages work in ERModernLook all of the standard 
file upload components don't.

So I've been working on one that will. I've got to say it's a pig of a problem. 
Mike had already done some heavy lifting on AjaxUpload but it required it's own 
form. Andrew Valums AjaxUpload.js  helps work 
around that. But getting the behaviour just right is tough. Widespread adoption 
of HTML5's file object cannot get here fast enough for me.

Anyway, here is a sample movie of what I've been working on, I'd love feedback 
on whether the UI behaviour makes sense.

Hi list,

Just to inform the Java Decompiler [1] plug-in for Eclipse is now

I'm using Eclipse 3.4.1.  I just followed the instructions here:

http://java.decompiler.free.fr/?q=jdeclipse

The steps headed "Installation of Equinox/p2 plug-in" failed—Eclipse  
told me it was already installed.  So I pressed on and completed  
"Installation of JD-Eclipse plug-in".  I take it the next step is to  
associate "*.class" with the class decompiler, but I don't see that  
listed as an option in the "Internal editors" list.  Have I missed  
something here?

[OT] - WWDC10

[Dev WO]

Hello womates,

just in case there are some of you with a "still working" ADC Premium with an 
e-ticket for WWDC2010 and they won't attend, maybe those tickets can be of help 
for some of us:)
Basically it could be a list of "everyone who are going to attend" and "the 
number of available tickets". We could put that all together and see how much 
we need to add to get tickets for all the attendee.
If there's only a couple of e-tickets available I vote for giving it to the 
"oversea" active person on the list like Anjo for exemple.

I think we need to move fast, tickets sold out really quickly last year.

I'm using Eclipse 3.4.1.  I just followed the instructions here:

http://java.decompiler.free.fr/?q=jdeclipse

The steps headed "Installation of Equinox/p2 plug-in" failed—Eclipse told me it 
was already installed.  So I pressed on and completed "Installation of 
JD-Eclipse plug-in".  I take it the next step is to associate "*.class" with 
the class decompiler, but I don't see that listed as an option in the "Internal 
editors" list.  Have I missed something here?

Re: Debugging

[Martin Samm]

JadClipse - cheers, will check it out.

Yep - the Fk column was indeed exposed as a class property.

Thanks all,
