 Status: Pending => Resolved

The idiom "python:path('request/something') or 0" no longer works due to a fix in the way exceptions are handled.  Instead, use "python:path('request/something | nothing') or 0".

Moving my testbed from 2.5.0b2 to 2.5.0b3 i get an error with a page template.

the line in the template:
  <span tal:define="global something python:path
  ('request/something') or 0;>

gives the following error:

Error Type: Undefined
Error Value: b_start not found in 'request/b_start', at line 167, column 47

This worked fine with 2.5.0b2

Would be glad if anyone could give me a clue...
