Hi John, Hi All,

debugging a process I noticed that

   1. in *utils.rb* the module *OpenWFE* contains 3 methods: [lookup |
   has | set]_attribute but "*unset_attribute*" is missing
   2. in *expressions/fe_value.rb* the *SetValueExpression* in it's
   method reply uses workitem.attributes[fkey] = xxx, to set the value
   instead of the above *set_attribute*. With the result that if fkey = "
   a.b.c"
   the latter causes workitem.attributes["a.b.c"] = xxx while with the
   former we can obtain workitem.attributes["a"]["b"]["c"] = xxx if
   workitem.attributes["a"] = { "b" => { "c" => xxx } } ( the dotted
   notation allows us to explore the hash ..., right? )


Can I correct this or is it wanted to be so?
If yes i should also the missing unset_attribute in 1), right?

Thanks for the precious help ;)
Bye
Tom
