Author: yoann

New Revision: 11109

Modified:
   prelude-correlator/trunk/plugins/lua/lua-idmef.c
Log:
Implement patch by Jeffrey C. Ollie <[email protected]>, which make IDMEF:getraw()
return a nil value (in place of nothing) if the retrieved element is empty.

This fixes an Lua error that occur when calling IDMEF:set() using the result of
IDMEF:getraw() on an empty element.
