As some of you may know, the Macromedia V2 Component Architecture allows you, to work with metadata in your classfiles. You can i.e. add a icon-file to your component , which display in the component panel// add an icon to your component
[IconFile("CarGame.png")]

With another metadata-tag you declare params as inspectable, which means that the user can edit this param. // make the variable speed inspectable by the user
[Inspectable(defaultValue="5")]
public var speed:Number;

If you want to hide the internal var name, you can give the param a “display name” which is displayed in the component inspector panel.// set default value, give display name, set type of value
[Inspectable(defaultValue="5", name="Car Speed", type="Number")]
public var speed:Number;

Now the bug. You can’t use square bracket in the name value. When i want to show the user a range of the value i usually write something like this: Car Speed [0-10]. Unfortunately, this is not possible because flash return a compiling error, when you use the squared bracket close ( ] ) in the name value of the inspectable metadata tag. Time for another bug report…
