Tapestry 4.12 (5/09), ognl-2.7 (5/10)
Description
I'm 0 for 2 in my bug reporting so let's hope I do better 
I have a shell component with two assets defined
.jwc:
<asset name="printStylesheet" path="css/print.css"/>
<asset name="screenStylesheet" path="css/screen.css"/>
<component type="Shell">
<binding name="stylesheets">
page.assets.pageStylesheet ?
new org.apache.tapestry.IAsset[]
{ assets.printStylesheet, assets.screenStylesheet, page.assets.pageStylesheet }:
new org.apache.tapestry.IAsset[]
{ assets.printStylesheet, assets.screenStylesheet }</binding>
</component>
When I go to my home page (which doesn't pageStylesheet) I get:
41096 [http-8180-Processor24] ERROR org.apache.tapestry.services.impl.HiveMindExpressionCompiler - Error generating OGNL statements for expression page.assets.pageStylesheet ? new org.apache.tapestry.IAsset[]

This did work with ognl 2.6 and an earlier snapshot version of tapestry. I'm happy to provide more information or anything that is needed to help identify the problem, I just need a little direction and I can do the leg work. Thanks.
