[flexcoders] Remote Objects not working with Modules
Hi guys, i am experiencing something weired. i have an application and i have broken it up into modules so as to reduce the size of the application so archive faster download speed for the app. anyhow, i use ColdFusion to retrieve, insert, edit and delete data from a database and when i use Remote Objects in modules there is no data retrieve or added, but when is use custom components method instead of modules with the very same code, the data can be inserted or retrieved. can someone please help me and clarify on how to successful use remote objects with modules to manipulate a database with ColdFusion as the back end. thanks
[flexcoders] Web Services and ObjectProxy question for the Flex Gurus
It seems like a common problem, I'm seeing tons of posts on the web, but no solid solution. I'm making a web service call which will return a complex data type, say Car. The Car has internal complex data types like Wheel, Door, etc. I'm using Flex 4 and I set the returntype for the webservice to return an array of Cars - Cars[]. If the web service returns more than 1, it successfully deserialized the data and returns an array of Car objects. BUT, if only one is returned, it returns an ObjectProxy, obviously because it cannot convert it to an array. Most solutions on the web show how to add this one item to an array. What I want is the actual object to be of type Car. If I change the returntype for the web service to return a single Car object, then when it returns one, it works, but more than one, it returns an array of ObjectProxy objects. I could check if the returned object is a single object, then spin through each attribute and convert it to a car, but because the car has other objects within it, they too show up as ObjectProxy objects, so I'd hve to spin through the tires, the doors, etc. which in my case is a lot of attributes, just to deserialize the object. Is there a solution for a web service to either a) always return an array, even if it is an array of 1, or b) a way for the Flex code to correctly deserialize both an array of Cars and 1 Car? Thanks!

Re: [flexcoders] Web Services and ObjectProxy question for the Flex Gurus
true this issue comes even with remote objects call , I exactly not get the solution , but put some check at the time of return ,if its object create an array or do the this on flex .

[flexcoders] Re: Web Services and ObjectProxy question for the Flex Gurus
Michael, The Flex SDK can do what you want, but the default behavior is for it to unwrap collections and enclosing types which only contain one item. This default was not a good idea, IMO. Have you tried setting Operation.forcePartArrays true? http://livedocs.adobe.com/flex/3/langref/mx/rpc/soap/Operation.html#forcePartArrays You will need to obtain the mx.rpc.soap.Operation from the WebService first. You can alter the default behavior by writing a custom deserializer (which is a non-trivial task, made more difficult by the ASDoc being turned off.) For more information about Flex WebService, see my slide show and YouTube video at http://www.slideshare.net/mslinn/using-flex-with-enterprise-web-services Mike I'm using Flex 4 and I set the returntype for the webservice to return an array of Cars - Cars[]. If the web service returns more than 1, it successfully deserialized the data and returns an array of Car objects. BUT, if only one is returned, it returns an ObjectProxy, obviously because it cannot convert it to an array.

No, i have not borrowed the code for popup editorut yes i am using the
popup editor.
Please see the code for Pop up at
http://ilikeflex.blogspot.com/ http://ilikeflex.blogspot.com/
Under 'Code for PopUp'
But my itemEditEnd event handler code is below.
private function onitemEditEnd(event:DataGridEvent):void
{
//trace(event.reason);
var datGrid:CheckBoxDataGrid=(event.currentTarget as
CheckBoxDataGrid);
event.preventDefault();
datGrid.destroyItemEditor();

I cannot remove event.preventDefault(); because my datagrid column has
nested datafield.

Re: [flexcoders] Re: 2 PopUpButton questions: force opening upwards + red and black item colors
There might be easier ways to get multiline text with bold and fontsize 16.
Setting wordWrap=true and some styles might just work.
Otherwise, it is time to read up on how to create custom item renderers. You
have to implement IMenuItemRenderer in your custom renderer.

Thanks! I will look into all of this.

This default was not a good idea, IMO. Have you tried setting Operation.forcePartArrays true? http://livedocs.adobe.com/flex/3/langref/mx/rpc/soap/Operation.html#forcePartArrays You will need to obtain the mx.rpc.soap.Operation from the WebService first. You can alter the default behavior by writing a custom deserializer (which is a non-trivial task, made more difficult by the ASDoc being turned off.) For more information about Flex WebService, see my slide show and YouTube video at http://www.slideshare.net/mslinn/using-flex-with-enterprise-web-services Mike I'm using Flex 4 and I set the returntype for the webservice to return an array of Cars - Cars[]. If the web service returns more than 1, it successfully deserialized the data and returns an array of Car objects. BUT, if only one is returned, it returns an ObjectProxy, obviously because it cannot convert it to an array.
[flexcoders] Re: Web Services and ObjectProxy question for the Flex Gurus
Thanks for the replies. I'm not wanting an array. Yes, I could just stick the returned single ObjectProxy in an array, but now I have an undefined object inside of an array. This works if I'm taking the returned data and binding it to some control, but I'm actually needing tp parse the returned data in an intelligent way. I'd like to access the object directly as the VO, not a generic object, that is, typed to my VO, not ObjectProxy. I understand why it does this, it does this because it was expecting an array of VOs and when it only gets one, it can't deserialize it to the VO. The problem is, how to get it to work in both cases (single object returned, and array of objects). The VOs are defined on the client side.

[flexcoders] Issue with item renderer in Flex 3
Hi All,
I am facing a problem in using item renderers. I have a checkbox as an item
renderer in a datagrid. When I check/uncheck the checkbox, the color of the
checkbox should change from its default color to yellow. And on click of a save
button, I am saving the changes to the database and refreshes the grid. But
what happens then is,due to the recycling of renderers, the yellow checkbox is
appearing on some other row/column. I know that this happens because I am not
resetting the yellow to default color. I also don't know where to reset the
yellow to default color.
This is what I did,..
on click of check box, in the click handler, i set the yellow color
setStyle('fillColors',['#eccd12', '#e9d76c','#eccd12', '#e9d76c']);
setStyle('fillAlphas',['1','1','1','1']);
also set a boolean variable isEdited to true
In override public function set data():void
{
if(isEdited)
{
//set yellow
setStyle('fillColors',['#eccd12', '#e9d76c','#eccd12', '#e9d76c']);
setStyle('fillAlphas',['1','1','1','1']);
}
else
{
//set default color
setStyle('fillColors',['#FF', '#CC','#FF', '#EE']);
setStyle('fillAlphas',['0.6','0.4','0.75','0.65']);
}
}
This doesnt solve the problem.
Can someone please help me in this?
Thanks

Re: [flexcoders] Value Object --- Object Proxy --- huh???
Hi Mark In the fairly large applications I've worked on, I've not had occasion to use Proxy, if you mean this: http://livedocs.adobe.com/flex/3/langref/flash/utils/Proxy.html Basically it lets you create an object that poses as something else, possibly supplementing it. For example, in the example given, they create a ProxyArray which actually derives from Proxy, but (dynamically) implements the properties, operators and methods of Array, adding sum() and clear() methods. Others may disagree, and I'd love to hear of good examples, but I would actually think twice before using this. You're sacrificing type safety and possibly performance. On the other hand, Value Objects (closely related to DTOs [Data Transfer Objects], and to be contrasted with Entity objects), are bread and butter things. http://c2.com/cgi/wiki?ValueObject Their identity is based on their state rather than on their object identity. This way, you can have multiple copies of the same conceptual value object i.e. two Date instances with the same day, month etc. represent the same date, whereas var employee:Employee might refer to different Employee instances at different times, in which case we're talking about different Employees. In a Flex app, VOs are typically created to represent messages. Your API (whether AMF, JSON or XML) will return flattened data which is then converted into an object instance tree structure (not to be confused with a class inheritance tree, if you're new to OOP). If you are creating these VO classes yourself (as opposed to using ones whose source is generated by tools provided by LiveCycle, WebOrb etc) you should resist the impulse to add business logic to them. They'll typically have nothing more than a few public properties. So you might have both an EmployeeVO and an Employee class, where EmployeeVO is a Value Object or DTO, and Employee is an entity. Hope this helps. I'm sure others will weigh in. - Richard P.S.

Re: [flexcoders] Value Object --- Object Proxy --- huh???
ObjectProxy is a generic VO. It is dynamic and can hold any properties and values. And it is slow. Best to create custom Vos that are strongly typed.

[flexcoders] Changing color of the PopUpButton
Hello,
I have a working code for displaying red and black entries
in the list of a PopUpButton (depending on the card suit).
However I'm missing the minor last touch: when the user
selects a red entry in the list and I assign its value to the
PopUpButton's label, I don't know how to change label's color.
I've tried several things and searched web...
Here is my code, please try it out and you'll see the problem -
Thank you

[flexcoders] Re: Web Services and ObjectProxy question for the Flex Gurus
Thank you Mike!!! This was EXACTLY what I was looking for. Once I have Flex
generate all of my VOs, I've added the following code to the sub-class's
constructor which does the trick for all of my web services without me
modifying the generated code.
public function MyClass() {
super();
for each (var operation:Operation in operations) {
operation.forcePartArrays = true;
}
Now all of my web services work as expected!

Michael,
The Flex SDK can do what you want, but the default behavior is for it to
unwrap collections and enclosing types which only contain one item. This
default was not a good idea, IMO.
Have you tried setting Operation.forcePartArrays true?
http://livedocs.adobe.com/flex/3/langref/mx/rpc/soap/Operation.html#forcePartArrays
You will need to obtain the mx.rpc.soap.Operation from the WebService first.
You can alter the default behavior by writing a custom deserializer (which is
a non-trivial task, made more difficult by the ASDoc being turned off.)
For more information about Flex WebService, see my slide show and YouTube
video at

Mike
I'm using Flex 4 and I set the returntype for the webservice to return an
array
of Cars - Cars[]. If the web service returns more than 1, it successfully
deserialized the data and returns an array of Car objects. BUT, if only
one is
returned, it returns an ObjectProxy, obviously because it cannot convert it
to
an array.
