You've got three options:
 
1) shove the id off into a member field, and grab it when the RO returns.  This is the least well designed response, since it can break in use cases where you've got multiple requests out and you don't just want last-out-wins.  Might be OK for your use case though.
 
2) send the id up to the RO, and have it include it in the response.  A little wasteful, since the RO doesn't care about the id, but in general this 'cookie' pattern is a way to maintain state across RO calls.
 
3) use closures.  you could do something like this:
 
 
private function chartClickHandler(e:MouseEvent):void
{
    var id:String = UIComponent(e.currentTarget).id;
    var roCB:Function = function(e:ResultEvent):void
    {
      nameList = event.result as ArrayCollection;
      currentState = "showNames";   
      gridPanel.title = id;
      myRemoteObject.getNomeForNames.removeEventListener("result",roCB);
    }
    myRemoteObject.getNomeForNames.addEventListener("result",roCB);
    myRemoteObject.getNomeForNames(id);
}
 
<PieChart id="..." click="chartClickHandler(event);" ... />

Subject: [flexcoders] Which chart was clicked

I have 3 pie charts which when clicked run the same remoteObject
method. Is there a way within the method that I can determine which
pie chart was clicked. I want to pass the id of the clicked chart as
a variable in the result function of the remoteObject method.

Thanks, Dave

<mx:PieChart id="Citrus"
click="myRemoteObject.getNomeforNames('Citrus')" showDataTips="true"
dataProvider="{citrusData}"/>

<mx:RemoteObject
id="myRemoteObject"
destination="ColdFusion"
showBusyCursor="true"
source="fungaldatabases.fungaldatabasesstats.stats"
fault="Alert.show(event.fault.faultString, 'Error');">
<mx:method name="getNomeforNames" result="showNames(event)">

</mx:method>
</mx:RemoteObject>

public function showNames(event:ResultEvent):void{
nameList=event.result as ArrayCollection
currentState = "showNames";
gridPanel.title = 'whould like to use the id of the chart
selected'
}
