Re: ECB-2.40 -- error in ecb-select-source when opening file - FIXED!

Hi,

Well, i think the problem is now identified and solved...s.b.

>2.  ecb-source-path-function = (ede-ecb-project-paths)

This is the key to our problem and solution - s.b.!

If you add a file F which does not reside in any path spezified in ecb-source-path then
ECB add temporally the directory of F to ecb-source-path
==> Therefore you have these entries in ecb-source-path.
But they should have gone when restarting emacs except the option
`ecb-add-path-for-not-matching-files' tells ECB that it should ask you for
saving these new path for future sessions. What is the value of
`ecb-add-path-for-not-matching-files'?

Well, the entries 4 and 5 came from 4.1. (s.a. my explanation) and the first 3 entries
came from 2.

ECB always adds the paths from
A) ecb-source-path and
B) returned from all functions of ecb-source-path-functions

Not in your case B are all path returned by the function `ede-ecb-project-paths' (s.a.
2.) - this matches with your 3 ede-cpp-root-project in your .emacs file.

Let's make a try: Set ecb-source-path-functions to nil and the first 3 entries should 
have been gone! 

Summary: You should take into account how to set ecb-source-path and ecb-source-path-functions!

Currently ECB does not eliminate duplicates. But maybe this would be a nice new feature......

Does this help?
