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.
