Flash Builder - RDS - LCDS - 1020: Method marked override must override another method

Question

I'm using RDS data modeller, the RDS fml file is working okay,
I can work with the tables, use services
but when I try to run the application I get prolems, and the problem states:

Type
1020: Method marked override must override another method.
_CityEntityMetadata.as
/xoffer/src/xoffer
line 219
Flex Problem
This issue extract is: for example: _CityEntityMetadata.as
    override public function getPropertyType(propertyName:String):String
        if (model_internal::allProperties.indexOf(propertyName) == -1)
            throw new Error(propertyName + " is not a property of City");
        return model_internal::propertyTypeMap[propertyName];
this for some tables
how does this present, I didn't do sth special, followed the how to online, already reinstalled the whole thing (flash builder 4.5.1, modeller 3.1.1)
workflow:
-> created in MySQL the Database
-> used the RDS config (this works)
-> generate the code and push to the server
-> make a datagrid and link it to a service
-> play => errors get detected
ps when I delete the override it is ok, but I don't think this should be the case....

Answer 1

I'm also experiencing this problem.  It's a real pain in the neck to have to do extended search / replace on certain method signatures to remove the override.
Anyone have a solution?
Thanks in advance!
