FastInject not detecting objectId in Parsley

Question

I have just started using Parsley recently and I ran into this issue. The thing is I have a custom component in my project, which is "configured" by Parsley and has a piece of code as follows:

<fx:Script>
<![CDATA[
            ...
            [Inject(id="dateFormatter")]
            [Bindable] public var dateFormatter:DateFormatter;
            ...
]]>
</fx:Script>

<fx:Declarations>
<parsley:Configure />
</fx:Declarations>

My problem is that I don't want Parsley to configure the component entirely. I want to simply use FastInject in MXML, instead of using Configure, like:

<parsley:FastInject objectId="dateFormatter" property="dateFormatter" type="{DateFormatter}" />

From what I found when I searched online, the objectId in FastInject is the same as [Inject(id="dateFormatter")]. Here's the source for that. Please correct me if I am wrong :).

But when I use it, I hit the following error: Error: More than one object of type mx.formatters::DateFormatter was registered

Does this mean that the ID of the property being injected is not being picked up? It works fine when I configure the whole component and use the Inject meta-tag, but I don't want to configure the whole component.

Can someone suggest a solution?

FastInject by id works if objects declared in the context have an id.

Context configuration

<fx:Declarations>
    <foo:FooBar1 />
    <foo:FooBar2 id="fooBar2" />
</fx:Declarations>

FastInject in your component

<fx:Declarations>
    <parsley:FastInject injectionComplete="handlerInjectComplete(event)">
        <parsley:Inject property="foobar1" type="{FooBar1}" />
        <parsley:Inject property="foobar2" objectId="fooBar2"/>
    </parsley:FastInject>
</fx:Declarations>
<fx:Script>
    <![CDATA[
        [Bindable]
        public var foobar1:FooBar1;
        [Bindable]
        public var foobar2:FooBar2;

        protected function handlerInjectComplete(event:Event):void
        {
            if(foobar1) trace("foobar1 available");
            if(foobar2) trace("foobar2 available");
    }
    ]]>
</fx:Script>

This works for me.
