Hi Dave, Sorrowfully, this is not that simple :(. Removing the line in question provokes a double analysis of 'f', which is bad in some cases (for example if you add a branch name f.f or something like that). Anyway looking at this problem I found a few other "annoyances" that I will also fix as soon as possible. Cheers, Philippe. -----Original Message----- From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch]On Behalf Of Dave Morrison Sent: Tuesday, March 05, 2002 4:25 PM To: roottalk Subject: [ROOT] Re: delimiter in branch name Hi again, It's never good form to reply to your own question, but ... if I remove the following line from TTreeFormula.cxx I recover the behavior of 3.01/06: % diff -u root_v3.02.07.orig/treeplayer/src/TTreeFormula.cxx root_v3.02.07/treeplayer/src --- root_v3.02.07.orig/treeplayer/src/TTreeFormula.cxx Thu Jan 10 16:09:45 2002+++ root_v3.02.07/treeplayer/src/TTreeFormula.cxx Tue Mar 5 17:06:16 2002@@ -1718,7 +1718,7 @@ if (current!=work) *(--current) = '\0'; // remove bracket. --i; // Skip dots that made be adjacent to the closing bracket - while (cname[i+1]=='.') i++; + // while (cname[i+1]=='.') i++; } } // Copy the left over for later use. With this line in effect, the empty "[]" is swallowed, the subsequent "." is skipped and the object name and that of its data member are concatenated. That search then fails.
