RE: [flexcoders] Array of object types returned from remote objects

2006-07-05 Thread João Fernandes
Tom,

How can you have missed everything ColdFusion team has been speaking about all 
this time? 
ColdFusion Extensions can make your life a lot easier (believe me). Generate 
those files and you'll see what must implement, but basically 
1) in your AS :
[RemoteClass(alias="mypath.to.my.cfcomponent.thiscaseReactorTomssql")] 
2) your CFC (VO in CF side):
Have a alias attribute in your component tag with the dot path notation 
like " mypath.to.my.cfcomponent.thiscaseReactorTomssql"
Have

You mean the ActionScript value object ? I'm guessing there is some

Choosing 'wizard' and then 'CFC' gives you the option to make ActionScript 
classes too. That's a big help.

Wish me luck :-)

RE: [flexcoders] Array of object types returned from remote objects

2006-07-04 Thread João Fernandes
Tom if you want to avoid casting all away in your flex app you can follow the 
"new" rules for mapping cfcs & AS.
Instead of returning an array of struts, return an array of components with 
 define in them (very same order or it won't work).
Better, right click on your AS file and use the CF extensions to generate your 
cfc. 

1) bind your AS class to your cfc generated object 
2) in your remote function call define returntype="mypath.to.my.cfc[]" <--- 
return type of array of mypath.to.my.cfc (don't know if it's mandatory)

If it's not clear , generate your AS & CFC based on your table and check what 
was generated.

RE: [flexcoders] Array of object types returned from remote objects

2006-07-04 Thread João Fernandes
I think (I might be wrong), that arrayElementType can only be defined for 
Arrays and not for ArrayCollection.

"These is filled in in the result handler of a service, which is having an 
array of objects sent to it. These objects have the same properties as the AS 
clas com.hw.foo.bar.vo.FileVO"

If you're using ColdFusion why don't you map your AS class to your CFC and get 
those objects correctly translated? Are you returning Reactor's TO by any 
chance?

My cairngorm2 model declares a public property that is an arraycollection:

These is filled in in the result handler of a service, which is having an array 
of objects sent to it. These objects have the same properties as the AS clas

At some other points in the code, I want to refer to

model.rejectedCreationRequests[i]
and get back a com.hw.foo.bar.vo.FileVO

Casting ( as FileVO) or the ArrayElementType hint don't seem to work.

I don't need to put the fully qualified class name in the hint do I ? The docs

Or change the declaration / add hint in the model for the ArrayCollection to

Currently, it's still just

Currently we're doing:
var accfiles:Array = event.result.awaitingCollectionByArchiving as Array;
model.rejectedCreationRequests = new ArrayCollection(files);
Which is fine, but it creates an ArrayCollection of objects.
Is there anyway to say 'this array you just got is an array of MyObjectType' ?

The current approach is causing us a few issues with data binding, because 
although we can make a dataGrid's dataProvider 
model.rejectedCreationRequests, the grids selectedItem is just an object, and 
if we try and cast it (var temp:MyObjectType = grid.selectedItem as 
MyObjectType) we get coercion errors :-(

[flexcoders] Array of object types returned from remote objects

2006-07-04 Thread Tom Chiverton
Currently we're doing:
var accfiles:Array = event.result.awaitingCollectionByArchiving as 
Array;
model.rejectedCreationRequests = new ArrayCollection(files);
Which is fine, but it creates an ArrayCollection of objects.
Is there anyway to say 'this array you just got is an array of MyObjectType' ?

The current approach is causing us a few issues with data binding, because 
although we can make a dataGrid's dataProvider 
model.rejectedCreationRequests, the grids selectedItem is just an object, and 
if we try and cast it (var temp:MyObjectType = grid.selectedItem as 
MyObjectType) we get coercion errors :-(
