My last note: my application is passing an asset to my Border, which invokes
my CustomShell
<component id="myAssets" type="MyAssets"/>
<component id="border" type="_comps:Border">
<binding name="externalScripts" value="ognl:
components.myAssets.assets.javascriptFilename"/>
</component>
In the Border.jwc
<parameter name="externalScripts" required="no"/>
<component id="shell" type="CustomShell">
<binding name="javascript" value="ognl:externalScripts"/>
</component>
