[flexcoders] Pass two arraycollections to one component

[Liam]

I need to pass two separate arraycollections to one component. I'm sure this is 
possible but I can't find anything online as to how to do this.

I thought I could do this but it only displays the last arraycollection:

>From main application:
<components:ApplData beginners="{beginners}"/>
<components:ApplData transfers="{transfers}"/>

With such little information, any suggestions?  Can I do this?

Thanks,
Liam
