Using cogre

Using cogre

[Andrea Crotti]

I discovered cogre quite recently and I think is great, but I still
didn't get how to use it correctly maybe...

Suppose I have some c++ files open, I call
cogre-uml-quick-class

I select the class and everything works fine.
Now if I want to add another class again to the same "graph" I do the
same but I always get

--8<---------------cut here---------------start------------->8---
Building UML diagram for "Statistic"
semanticdb-find-translate-path-default: Wrong type argument: stringp,
nil
--8<---------------cut here---------------end--------------->8---
why is that?

And also what if I want to add manually some parameters?
Every parameter is something like
--8<---------------cut here---------------start------------->8---
 ("beacon_is_set" variable
  (:type "bool")
  (:filename "/Users/andrea/uni/aachen/thesis/padsim/pad.cc" reparse-symbol classsubparts)
  [569 588]))
--8<---------------cut here---------------end--------------->8---
which I would avoid of course to write by hand if possible...
