[flexcoders] Re: Defining services in AS in ServiceLocator

2006-07-07 Thread ben.clinkinbeard

Once again, Jester comes through in the clutch.

As an aside, I was able to use an AS class that subclassed
ServiceLocator also, but I like the option of mixing better. The
reason I am exploring this is because I have a need for dynamically
loaded WSDL paths, and apparently you can only do that in
mx.rpc.soap.WebService, not in its MXML cousin. I don't have time to
thoroughly test that theory tonight (although preliminary tests look
very promising), but will update that thread
(http://groups.yahoo.com/group/flexcoders/message/42536) once I get
some definitive answers.

Thanks again Jesse,
Ben

RE: [flexcoders] FDS question

2006-07-07 Thread Rob Rusher













It sounds like you have a fundamental misunderstanding
of what FDS does.

FDS is for more real-time data.

 

If you just need to talk with a back-end,
you will use the RPC classes in the API.

 

You can read more on both in livedocs:

As far as licensing goes, consult your
sales rep. They have the answers.

Subject: [flexcoders] FDS question



 







OK I have been playing with flex for a couple of weeks
now and we are planning on 
building out a rather large application in flex. The application is going to
replace several 
current apps one of wich is web based the rest are not. 

I am trying to get my head around the whole FDS thing. Our product will be a
medical 
database. There are currently several different modules within the existing
apps. The way 
I was planning this, each one would become its own flex app. the reason for
this is to try 
and keep the swf file size somewhat reasonable. 

Currently our thinking is to connect to the data through web services sending
XML data to 
a JSO file that then will communicate with a JAVA based API back to the MySQL
backend. 
What, if anythign would FDS bring to the table? Still not sure how it is better
than XML 
based solution.

Also a concern with FDS is the pricing structure. will each FDS file be
considered a 
different app, therefore each one require a license ($6k or $20k)? If each app
was 
assigned only one processor on the VM based server would it be able to use FDS
express??

I am just not seeing how FDS figures into the equasion. Is it faster? if so
how? Does it 
save coding time? if so how? Does it eliminate need for a java API? if so how?

Thanks for any help.

[flexcoders] PopUpMenuButton icon not working?

2006-07-07 Thread Shannon Hicks






I've tried adding an 
icon to the PopUpMenuButton, but it doesn't seem to work.
 
It shows the icon in 
Flex Builder, but not in the compiled SWF.
 
I've added icons to 
every other type of button (the same icon, called from the same component in the 
same way), and they work fine.
 
Maybe it's a 
bug?
 
Code:
     
 
  
   
   
  
 

 
If you're going to 
try it, be sure to actually create the gif, otherwise FlexBuilder throws some 
compile error about not finding the gif :)

RE: [flexcoders] FDS question

2006-07-07 Thread David Mendels

Hi,

Let me suggest a few articles that will help you understand Flex Data
Services:

http://www.adobe.com/devnet/flex/articles/architecting_rias.html

http://www.adobe.com/devnet/flex/articles/refactoring_flex.html

http://www.adobe.com/devnet/flex/articles/intro_fms.html

http://www.adobe.com/devnet/flex/articles/rpc_service.html 

These are all new articles as of last week.

And, the key getting started section of the docs:
http://livedocs.macromedia.com/flex/2/docs/wwhelp/wwhimpl/js/html/wwhelp
.htm?href=0138.html


Lots of material above.  Please let us know what you find most useful
and whether we address your questions about FDS.

As for pricing, I think we have this explained on a FAQ somewhere, but I
can't find it right now. I expect someone else from Adobe can help here.

Currently our thinking is to connect to the data through web services sending XML data to
a JSO file that then will communicate with a JAVA based API back to the MySQL backend.What, if anythign would FDS bring to the table? Still not sure how it is better than XMLbased solution.
It depends on what you are trying to do. For basic remoting (essentially RPC) it is much easier than sending XML data because you can send real objects back and forth and it automatically converts. Its almost like making local calls except for the results are asynchronous (which has its good and bad points). But if you already have a solution in place there is no reason to upset the apple cart.
The area where there is at least theoretical benefit is in stuff that uses the messaging platform. There are two general areas that messaging is used. The first is to support the ability to maintain an up to date version of data between multiple clients. So if you have a database and one client changes some data then that data would change on the screens of other users who were looking at that data.
The second area is using messaging in its raw form. By this I mean sending data or messages between connected clients. Imagine, for example a chat server. Not that this is the best example, but just so you get the idea. The issue here, for those of us familar with flash media server and other socket server technologies, is whether any of us would really use FDS for that purpose. It seems to me, and others who I have been discussing this, that FDS may be overkill and there may be more appropriate (read simpler) technologies like FMS.
I think it will take some time to really understand where FDS fits in the application development world beyond remoting, for which it is very convenient. The issue though with using it for remoting is if you need to scale it gets very expensive. Before FDS, the remoting solutions were either free (open source) or under $1000 per server. FDS is 20k per server.
Also a concern with FDS is the pricing structure. will each FDS file be considered a
different app, therefore each one require a license ($6k or $20k)? If each app wasassigned only one processor on the VM based server would it be able to use FDS express??If you are using the same data model, I am sure that you are fine. I cant imagine (tho perhaps we should wait to hear this from adobe) that they would thing that different connected apps all working off the same data model would be different applications.
I am just not seeing how FDS figures into the equasion. Is it faster?
It is faster than XML because it is binary. if so how? Does itsave coding time?
Yes if so how? By making access to java from flash feel like making local calls. It gives you freedom to just need to call a function and to be able to gain access to it woithout really thinking about it.
Does it eliminate need for a java API? if so how?Dont quite understand this one. The idea with remoting is that you can call any of your java functions from flash.
RegardsHank
