[fpc-pascal] scope error? duplicate identifier property and parameter

[Dale Welch]

I am getting an error compiling with fpc 2.1.1 under lazarus with duplicate identifier
that seems to be a scope error.  Under lazarus all you have to do is add
any dataset and add an onposterror event handler. 
it doesn't like that "Action" is both a property of an object and a parameter of a procedure in that object.
Action is defined as a published property in form.
then it is also defined as ... 
    property Action: TBasicAction read GetAction write SetAction;
    published property Action;
    procedure MemDataset1EditError(DataSet: TDataSet; E: EDatabaseError;   var Action: TDataAction);
    procedure MemDataset1PostError(DataSet: TDataSet; E: EDatabaseError;  var Action: TDataAction);
