Dear Cocooners,
today, after having upgraded our Cocoon build to the latest revision
from trunk, we started getting NPEs from a project that had worked
perfectly until then. Turns out the NPE was caused in a subsitemap
while trying to use the global input module to reference the value of a
global variable that was defined in the same subsitemap.
I started looking for differences between our app and the Cocoon
samples, where the global input module seems to work fine, and I
concluded that the only difference was the the samples' top sitemap had a
<map:component-configurations>
<global-variables/>
<map:component-configurations>
section, whereas our toplevel sitemap did not. So I added an empty
<global-variables> element to ours too and the NPE went away!
So, apparently, you MUST put a <global-variables> element in the
toplevel sitemap in order to declare global variables in a subsitemap.
Is this a bug or is this intended behaviour?
Looks like a bug to me.
