Hi
Sorry
for the delay.
When
serializing a query from CF the default return type is an ArrayCollection of
untyped objects. In Java, I’m going to have to be a tad less “certain” but when
I last worked with a Java developer it was returning an ArrayCollection of
untyped objects. I’m almost dead certain that all my research at the time
pointed to ArrayCollection as the default “replacement” to the old Flash
Remoting RecordSet object relative to Flex 2. In CF I discovered last week that
the only way to force CF to return an ArrayCollection of typed objects was to
add __type__ as a column in the recordset with that column containing a
string of the object type in Flex. I personally haven’t tested the theory
yet.
Any,
that aside, are you saying that it currently works to add the same attribute
handling to class members (properties and fields)? Or that you would have to
check in a change that would allow it? I was trying the attribute last week and
it was throwing an error in Visual Studio. Perhaps I had an outdated
build.
I’m
not in an instantaneous hurry, if you’re planning a release in the next week or
so I can wait. Right now I’m just prototyping client side code and doing mockups
of the GUI before I start spending time connecting to the
backend.
Thanks
Zoli – I’m really enjoying working with FlourineFX.
Sincerely

Hi
Mark,
Yes, the
same attribute handling can be added to class members (properties and
fields).
Related
to your question "why aren't automatically turned into ArrayCollection"...did
you check that CF and Java do this automatically?
For
example this conversion table http://livedocs.adobe.com/flex/201/html/ent_services_config_097_08.html#270405 does
not even mention what rules the Java RowSet mapping
follows.
If you
need it urgently then I will commit the required changes to the SVN (a new
release is planned soon)

Serialization of DataTable
Hi
Is there
anyway to change the default handling of how DataTables are serialized in
FlourineFX.
The [DataTableType("...")] only seems to work with methods
and I have classes that I need to send to Flex that have complex data in them
including several that have DataTables stored in publicly accessible properties.
Thus far my workaround was to write a method that simply serializes a DataTable
into a ArrayCollection of Hashtable's so instead of storing a DataTable in the
class property I store the ArrayCollection. I've never quite grasped the concept
of why all DataTables aren't automatically turned into ArrayCollection of
generic objects when passed back from Flourine. In my case, I have to write an
Flex app that needs to be completely agnostic to the backend server. We have to
create .NET version, ColdFusion and perhaps Java versions of the backend to
satisfy the requirements. Thus I need to standardize how DataTables are sent
back to match how CF or Java would.
A sample case I face would
be:
on Facade calling a method called login(username, password)
returning an instance of User if login successful. User contains
information about the user, the basics stuff as well as information about what
tasks they need to perform today and what parts of the system they have access
to. In theory I could call 3 times to the server to do this, but why call
the server needlessly when one call would suffice. In an ideal world the concept
of the [DataTableType("...")] would apply to public properties as well as
methods.
I will admit I'm not a heavy hitter in terms of C# programming
so before I start tearing into the source code of FlourineFx or pulling my hair
completely out I thought I'd ask.
Sincerely
Mark R.
