I have to agree with you, Carlos.  It would be nice have a package
like "SpringAS" or something of the sort in Cairngorm or else where.

[flexcoders] Re: FDS/Hibernate/MySql data update question

[jwp2k_uva]

Robert, 

Thanks for the design input.  I guess there is no helping it if I want
MySql database to have heterogeneous accessors.  My preliminary search
indicates that Oracle my be the only db that supports change event. 

By the way, nice work with SearchCoders.com/felx app.  It looks awesome.

[flexcoders] Re: FDS/Hibernate/MySql data update question

[jwp2k_uva]

Robert,

Thanks a million for pointing out DataServiceTransaction ;)  This is
awesome.  

I wonder now whether there is a db change event support in MySql/JDBC
connector that allows a java object to call DataServiceTranaction
functions as you described below whenever the database of interest is
changed regardless of who (.NET, PHP, etc.) changed it. 

You've been a great help.  Thanks, again.

- Jae

[flexcoders] Re: IoC framework for Action Script

Matt, Adobe, et al.

Has there been any progress in the area of IoC for ActionScript?

[flexcoders] FDS/Hibernate/MySql data update question

[jwp2k_uva]

Dear Flexcoders,

In a FDS/Hibernate/MySql setup, what happens if a data row is directly
updated in the MySql database?  Is there a simple way to update the
flex application with the updated data row?

Thanks a million. 

[flexcoders] Race condition in RichTextEditor

[jwp2k_uva]

I'm in the process of extending RichTextEditor component with
"Ctrl-b", "Ctrl-i", and "Ctrl-u" keyboard formatting options. 

Conceptually, it's quite simple.  For example, "Ctrl-b" will dispatch
a mouse click event from the RichTextEditor's boldButton.  However,
the following code will only work if some text is highlighted.  

Additionally, this code in debug mode with a breakpoint will always
work.   

If you know of a way to address this without adding empty cpu cycles
or rewriting RichTextEditor.mxml file, please let me know.

Thanks.

---
note, rte is a RichTextEditor object.

private function InitializeComponent():void 
{
   rte.addEventListener(KeyboardEvent.KEY_DOWN, keyDown);
}  

private function keyDown(event:KeyboardEvent):void
{   
   if ((event.ctrlKey) && (event.charCode == 98)) // "Ctrl-b"
   {  
  rte.boldButton.dispatchEvent(new MouseEvent(MouseEvent.CLICK));
   }
}

--Ugly workaround-
private function keyDown(event:KeyboardEvent):void
{   
   if ((event.ctrlKey) && (event.charCode == 98)) // "Ctrl-b"
   {
  rte.boldButton.setFocus();
  // Add empty cpu cycles 
  rte.boldButton.dispatchEvent(new MouseEvent(MouseEvent.CLICK));
   }
}

[flexcoders] How I can get the benefit of both startDrag() and DragManager.doDrag()?

[jwp2k_uva]

Hey guys,
  
I'm looking to create objects, i.e. boxes, that I can drag around to
different locations and have the ability to link to each other via
drag and drop operation.  The objective that I'm trying to achieve is
similar to the following example.

http://weblogs.macromedia.com/khoyt/archives/2006/11/flex_associatio.cfm

The above example would have been perfect, except the boxes cannot be
dragged to different locations.  

At this point, I hit a road block in trying to handle mouse events
directly and I would greatly appreciate your elegant approach.

Thanks!
