Problems with script input symbol

I am getting an error which states that an input symbol I defined in a script file is required but not specified.  Here is an excerpt from the script

 

<script>

      <input-symbol key="button" required="yes" />

      <input-symbol key="direction" required="yes" />

 

(Direction is the thing I am having trouble with.)

 

And here is an excerpt from the jwc file

 

<component-specification allow-body="no" allow-informal-parameters="yes">

      <property name="direction" />

      

      <component id="insertChangeDirectionScript" type="Script">

            <binding name="script" value="literal:ChangeDirection.script" />

            <binding name="button" value="components.button" />

            <binding name="direction" value="direction" />

      </component>

      

      <component id="direction" type="Hidden">

            <binding name="value" value="direction" />

      </component>

      

      <component id="button" type="Button" inherit-informal-parameters="yes">

      </component>

</component-specification>

 

If this isn’t what you do, then what is?

 

Thanks for your help,

Rob

Looks good to me, component.button is probably non-null, but direction
may be null, causing the error.
