Installed Flash Builder 4 in Eclipse 3.5/Springsource Tool Suite - cannot debug Flex

Question

I'm new to Flex.  I tried setting a breakpoint in one of the functions in my .mxml file and the debugger does stop at that breakpoint.  Here is the .mxml file, with the breakpoint set at the line highlighted in red below.  We are trying to use Flex as a front end with Java/Spring at the back end.  Thanks!
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:Script>
        <![CDATA[
            import mx.rpc.events.ResultEvent;
            import mx.rpc.events.FaultEvent;
            import mx.controls.Alert;
            import mx.collections.ArrayCollection;
            [Bindable] private var contacts:ArrayCollection;
            private function resultHandler(event:ResultEvent):void
                contacts = event.result as ArrayCollection
            private function faultHandler(event:FaultEvent):void
                Alert.show(event.fault.faultDetail);
        ]]>
    </mx:Script>
    <mx:RemoteObject id="ro" destination="contactService" fault="faultHandler(event)">
        <mx:method name="findByName" result="resultHandler(event)"/>
    </mx:RemoteObject>
    <mx:ApplicationControlBar width="100%">
        <mx:TextInput id="searchStr"/>
        <mx:Button label="Search" click="ro.findByName(searchStr.text)"/>
    </mx:ApplicationControlBar>
    <mx:DataGrid id="dg" dataProvider="{contacts}" width="100%" height="100%"/>
</mx:Application>

Anyone else have this issue? It happened on two different machines. I had to download a fresh copy of Eclipse and set it up twice - once for FB3 and once for FB4. :-(
