[flexcoders] RE: AS3 codegen

[Peter Martin]

We are still using this approach on our projects. To run it inside of
Eclipse is a bit of pain as you need to write an Ant script and then
configure it as a builder on your project. When you configure it you
probably want to take care of which resources trigger the build
otherwise it will running with every change.

To be honest I am not a great fan of XDoclet2 - I would rather see a
native plugin for Eclipse. A quick solution is maybe to write a plugin
for XDoclet, which does provide a plugin for Eclipse.

I noticed that this post was over a year old, but I am wondering if  
the codegen plugin is still appropriate for use.  We have over 50  
Java objects that we would like to generate AS3 VO from for a  
Cairngorm app.  Can anyone advise...

[flexcoders] Re: Cairngorm's Anaemic Domain Model

[Peter Martin]

No Cairngorm Enterprise is still an internal project. We are currently
developing our first customer project on Cairngorm Enterprise. Once we
have proven it we will then look to release to the community.

RE: [flexcoders] Re: Cairngorm's Anaemic Domain Model

[Peter Martin]

I thought at this point it is worth jumping in to talk a bit about
Cairngorm Enterprise, which we are currently working on.

 

With Cairngorm Enterprise one of goals is to promote an application
model on the client (RIA) and a domain model on server. We see the
application model being a good OO model that reflects the UI and tells
us about the entities and their relationships that we are surfacing. It
will also encapsulate all the business rules that apply to the UI. I see
this being different to the domain model and the business rules that
reside on the server. Next, we see the application model being
responsible for communication with the server-side i.e. it will call
remote services, consume messages, produce messages and contain managed
data collections. It knows when it needs to retrieve data from the
server, it knows when it needs to update server and it knows what to do
when data is pushed from the server.

 

This sort of shifts the concept we have at the moment, whereby you call
a command, which may invoke a service via a delegate. In essence we are
going to move the delegates behind the model and have the command call
an operation on the model. This is not saying what we do today is wrong,
but recognizing different applications have different needs. A simple
application certainly doesn't need this level of complexity - Cairngorm
today is just fine.

 

>From our observations as the complexity of an application increases we
see people treating the ModelLocator as a session for storing data that
comes back from the server. There is no application model that shows the
entities and their relationships, this is often left to the view to
piece together. To help with this we have introduced the concept of an
operation, which is effectively your IResponder. When an operation is
executed on the delegate it creates an operation, which is responsible
for updating the application model. The idea then is that an operation
can perform any post-processing, which is required on the data. This
allows the application model to be update correctly - quite often when a
legacy application is involved the data that comes back from server
isn't in a form that reflects how it is going to be viewed. We would
deal with that in the operation. In essence it would be nice to see VOs
/ DTOs being used for transporting data rather than making their way in
to the view via the ModelLocator.

 

We hope by encouraging an application model it will stop people having
to code allot of the logic in to the views and also make unit testing
easier. If we had a well encapsulated model it would be easier to unit
test than a bunch of views.

 

In saying this we can't force people to create an application model nor
are you prevented from doing so today. If you want to build an
application model in Cairngorm today you can and I know people do. Our
goal here is to encourage this in your design and to promote this
approach within Cairngorm Enterprise. In addition we want to emphasize
security and make it inherent within Cairngorm Enterprise by adopting
the "safe-by-default" mantra.

 

We have already done allot of work on Cairngorm Enterprise and there is
more to do - so now commitment just now as to when we will release it.
Certainly I would like to solicit your feedback on the above and hear
your ideas.

My question isn't about the model locator. It's about logic, or lack
thereof encapsulated within the domain objects.

[flexcoders] Web Services in Cairngorm 2.1

[Peter Martin]

There have been a number of postings across the
various newsgroups regarding Web Services behaving differently in Cairngorm
2.1.

 

The problem is due to ServiceLocator no longer
extending UIComponent. As such, loadWSDL() is not called automatically.

 

To call a Web Service operation you will need to call
loadWSDL() yourself, for example:

 

webService.loadWSDL();

var call : AsyncToken = webService.GetQuote.send(
stockSymbol );

call.addResponder( responder );

 

In the next release of Cairngorm we will do this
automatically for you in the ServiceLocator.

[flexcoders] Re: DestinationLocator (Cairngorm 2)

[Peter Martin]

You are correct it should have a constructor and a getInstance()
method. At the time of writing it I only wrote it to work with
SecureDestinationLocator so there was no need - or that's my excuse
and I am sticking with it ;).

I will update the code on my blog so DestinationLocator can be used on
it's own.

RE: [flexcoders] Re: Resizing a Panel

[Peter Martin]

Thanks.

 

It sounds like my implementation is very similar
to yours. I sorted my problem by adding setCapture(); to my mouseDown handler
and releaseCapture(); to my MouseUp handler. I also put event.updateAfterEvent();
in my mouseMove event handler to be on the safe side.

hi Peter, 

I'm using a combination of mouseDown, mouseMove

bottom right black grip. (there's a x/y delta between mouse down point and the
top/left point of black grip)

[flexcoders] Resizing a Panel

[Peter Martin]

I have created a Window component (in Flex 2 beta 2) that subclasses
TitleWindow. It allows the user to resize the window by grabbing the
bottom corner. It works fine if you are making the window smaller,
however if you are making it bigger Flex can't keep up with the mouse,
unless you go very, very slowly.

What I have is an event listener that handles onMouseMove and sets the
width and height to mouseX and mouseY.

Thanks
