RE: [flexcoders] Converting Java POJO to Actionscript Errors
Hari-
THanks for your response. I tried that but I got a
compilation error that there is no method with the
name MyPojo. I suppose that means I have to manually
write the underlying ActionScript class for my Java
POJO?
That just seems like a really bad implementation
design b/c if MyPojo Java class changes, then I have
to manually change my ActionScript class. urr...what
am I missing?!

Gang-
I'm a newbie and all the flexdocs on MM's site
couldn't give me a
concrete answer. I have a datagrid that is populated
from an ArrayList
of POJO's (using the remote object). That works
fine.
I then have another method that is called 30 seconds
later then
returns a single POJO (of the same type from the
POJOs returned in the
first method). I then try to add it to my datagrid
using the
myDatagrid.addItem(newObj), but I get the below
debug error.
Warning: Reference to undeclared variable,
'_global.com.MyPojo'
at mx_utils_ClassUtil::findClass()
Warning: valueOf is not a function
at mx_utils_ClassUtil::getFlexClass()
Is there a special way I need to declare 'newObj'
(which I pass into
the datagrid.addItem() method), or do I have to
explicity write the
AS-equilavent class of my Java POJO class?
I would think Flex could convert this class for me,
but I'm obviously
missing an important step to add it to the
datagrid/dataprovider.
Thanks in advance for your help.

RE: [flexcoders] Converting Java POJO to Actionscript Errors
Hi,
First couple of questions - did you register your POJO with AS class
using Object.registerClass( ) method?
What is the constructor method of you Pojo ?
After both of above are in place(implemented) then you can create new object
of your POJO type and assign your newly returned object to it and then add
this new object to your datagrid using myDataGrid.addItem( );
This is what I did.
AS class looks like
class classes.MyPojo
{
public var myArray:Array;
private static var registered:Boolean = Object.registerClass(full path
of you java class goes here, classes. MyPojo);
}
In my MXML you can ignore statements which sets initial attribute
values
function addRow()
{
var oNewItem:Object = new MyPojo ();
oNewItem.adj_num = 12 ;
oNewItem.adj_type = ;
oNewItem.adj_category = ;
oNewItem.adj_amt_terms_desc = Doodi;
oNewItem.adj_reporter_applied_flag = N;
oNewItem.adj_sign = Additive;
oNewItem.adj_factor = ;
oNewItem.adj_order_applied = 12;
myDataGrid.addItem(oNewItem);
focusNewRow();
doLater(this,focusNewRow);
}
Thanks!
Hari

RE: [flexcoders] Converting Java POJO to Actionscript Errors
(Hi suzy, firstly, I'm a little confused as to how Kevin Ewok's response
turned into your message - are you saying you're having the same issue
as Kevin? Let me first comment on Kevin's issue which will provide good
background for yours...).
On looking again at the warning Keven is getting from ClassUtil it means
that he didn't link in the com.MyPojo class to his SWF... that is, the
compiler didn't include the AS class because it wasn't referenced
anywhere.
Having a dummy variable of com.MyPojo type is one way to cause a
dependency on that class to have it compiled and linked in to the SWF.
But, furthermore, by using Object.registerClass() you can avoid the
ClassUtil issue altogether because the player will attempt to create
types for you from the registerd information while processing the AMF
response before the ClassUtil gets a chance to look at the result.
The ClassUtil is a legacy system from Flex 1.0 SOAP-based RemoteObject
(which is not supported in Flex 1.5) where by you could use a special
_remoteClass property to map client/server types since
Object.registerClass wasn't useful for non-AMF communication (i.e. XML
transactions are just strings and thus don't' get processed by the
player). Since Flex 1.5 RemoteObject only uses AMF, the _remoteClass
method is not suggested for Flex 1.5 and you should use
Object.registerClass().
Now, for Suzy's question...
Essentially what you're looking for here is that Remote POJOs turn into
plain old dynamic Objects on the client, right?
The problem is that in Flex 1.5 RemoteObject still has the deprecated
_remoteClass property in the response (which you should be able to see
in the AMF trace output).
The old ClassUtil is designed to always do this translation for you if
it finds the _remoteClass property... that is, it expects that typed
POJOs map to a corresponding AS type (that must be available at runtime
from the SWF).
By calling Object.registerClass you could bypass the ClassUtil's
translation attempt altogether... and, actually here's an idea, perhaps
you can trick the player into registering your remote POJO class to just
plain old Object to get a dynamic object back?
