NRE under certain circumstances in Asset subsystem

[Frank Quednau]

Hi there,

I am using the following assets file:

"jquery is scripts/jquery.js

pagination includes scripts/jquery.pagination.js,styles/pagination.css

jquery-ui includes scripts/jquery-ui-1.8.12.custom.min.js,styles/
jquery-ui.css

codehighlight includes styles/SyntaxHighlighter.css,scripts/
shCore.js,scripts/shBrushCSharp.js

site includes styles/site.css,scripts/rf.site.js"

when I use those assets in the ui markup (Asset being a shorthand for
WriteAssetTags etc.):

<Asset name="jquery-ui" />
<Asset name="site" />

All's fine. But also writing <Asset name="jquery" /> gives a NRE. The
same happens when I add jquery to the "jquery-ui includes ..." part of
the assets file.

However, the NRE seems to happen after rendering. In both cases the
rendering works correct which is easily verified since any missing bit
would fail core functionality of the page.

The stack trace is shown below, I hope this somehow helps to pinpoint
what could be happening:

Frank,

Can you show the file structure you've got under /content?

Did you get any closer to what was causing the NRE?
