David Kjerrumgaard commented on FALCON-598:
-------------------------------------------

To reproduce the error, just submit and then schedule a process with only 
inputs defined like so:

<process name="ErrorGeneratingProcess" xmlns="uri:falcon:process:0.1">

    <clusters>
        <cluster name="ClusterName">
            <validity start="2014-08-01T00:00Z" end="2016-03-31T00:00Z"/>
        </cluster>
    </clusters>

    <parallel>1</parallel>
    <order>FIFO</order>
    <frequency>days(1)</frequency>

    <inputs>
        <input name="input" feed="FeedName" start="today(0,0)" 
end="today(0,0)"/>
    </inputs>

    <workflow name="Workflow" version="2.0.0" engine="oozie" path="" />

</process>
