[flexcoders] Maintaining Login Data in Flex

[stinasius]

Hi guys i came across a very nice post on "Maintaining Login Data in
Flex" and since i was working on a project that required
authentication using a coldfusion backend and a database, this post
caught my eye. how do use the following class to maintain login data
and access it from anywhere in my application. here is the like to the
tutorial
"http://www.anujgakhar.com/2007/11/07/maintaining-login-data-in-flex/";
and here is the class

"UserInfo.as"

package classes.UserInfo
{
public class UserInfo{
private static var myUserName:String = "";
private static var myFullName:String = "";
private static var myEmail:String = "";

public static function get UserFullName():String{
return UserInfo.myFullName;
}
public static function set 
UserFullName(param:String):void{
UserInfo.myFullName = param;
}
public static function get UserName():String{
return UserInfo.myUserName;
}
public static function set UserName(param:String):void{
UserInfo.myUserName = param;
}
public static function get Email():String{
return UserInfo.myEmail;
}
public static function set Email(param:String):void{
UserInfo.myEmail = param;
}
public static function getInstanceMemento():Object{
var o:Object = {
myUserName: UserInfo.myUserName,
myFullName: UserInfo.myFullName,
myEmail: UserInfo.myEmail
};
return o;
}
public static function 
setInstanceMemento(param:Object):void{
UserInfo.myUserName = param.myUserName;
UserInfo.myFullName = param.myFullName;
UserInfo.myEmail = param.myEmail;
}
}
}

Re: [flexcoders] Repeater Selected Index

[Haykel BEN JEMIA]

If tab2 is selected then you should see the content of tab2. If you are
seeing the content of tab1, then it seems like after refresh you are putting
the data of tab1 in tab2. What happens when you select the other tabs when
you are in this situation after refresh? Are the tabs displaying the correct
data? How are you creating the tabs and what are you doing on refresh?

RE: [flexcoders] Re: Explain "override public function"

[Alex Harui]

If your override is exactly as you posted:
override public function set data(value:Object):void { }

then the override never passed the value to the base class implementation so 
the value wasn't stored and the debugger will read from the "get data()" 
function and show you a null.

In the base class the setter does this:

_data = value;

And the getter does this:

return _data;

where _data is defined as:

private var _data:Object;

I don't know the circumstances, but sometimes the framework passes a null to 
set data.  It is not uncommon to see a test for null in the override. I know 
that there are some "buffer" renderers created, perhaps they get a null?

Also to the OP, do you still need an answer to "Explain 'override public 
function'"?  It is basic OOP syntax, but I'll give it a few sentences if you 
need.

I forgot to say - if your data attribute is null there's a problem with the
dataprovider.

Try using the default renderer if you still have trouble with yours. The
Tree control in the docs has an excellent example, so work your data into
that until you find the problem.
