Full error message: 1144: Interface method set data in namespace is implemented with an incompatible signature in class.
<package:class><mypackage:myclass></mypackage:myclass></package:class>
This error appears in Flex Builder / Eclipse on the Problems Tab.This error refers to the fact that an extended class named <package.class> with an over ridable function has a correspondent override in <mypackage:myclass> that doesn’t match the overrided function. To be more specific i’ll give you an example:
Let’s say we want to create a custom data grid header renderer and in order to do this we will create a class VerticalHeaderRenderer that will extend DataGridItemRenderer. In the class VerticalHeaderRenderer we will override the setter function for the data property like this:
override public function set data(value:Object):void{
local_var = value.toString();
}
This is the correct version and it will not give the error mentioned in the title but if we have a function that has a parameter of a different type then Object or a different return type we will receive the error.
Basically this error tells us that we are trying to override a function with different parameters or different return value type. So to escape this error you must ensure that the override is made correctly.
Hope this helps.
Good luck.

It happened to me once when using:
public function funcName()
{
// function body
}
instead of
public function funcName() : void // <== the diference.
{
// function body
}
The clearly say in the help that the signatures must match "exaclty".
Thanks Chirs , I fixed the error with referring to your useful and simple example.NICE~
In my case error disappeared itself after recompiling.
