Still present in Zope 2.7 beta 2.

I'm on Windows, btw - that might be relevant, as this is a line ending problem.

It looks like people can get Plone running under Linux with 2.7.

Yes, we've been running Zope 2.6.x and CMF 1.4 as the base for Plone 1.1 for the past months now without problems.

Have you been able to confirm that this bug does *not* happen when running Zope 2.6.X and CMF 1.4?

I can confirm that this bug still exists in the beta1 release of Zope 2.7.

I also suggest that the rating is upgraded to critical, as this affects 95% of the page templates out there. It's very very common to have line breaks in TAL expressions.

As it stands now, Zope 2.7 breaks all my CMF based products. I'm not sure whether this is a CMF or Zope problem.

Using Zope 2.7 and CMF 1.4.

Just a note to say that this was using CMF 1.4

When a filesystem based ZPT (as would be used in a skin), has a TAL experssion like the following:

<td tal:content="python:DateTime.Date(here.end())">

there is no problem, however:

<td tal:content="python:DateTime.Date(
here.end()
)">

causes an exception, which doesn't cause a red exclamation mark in the ZMI, but on looking in the ZPT in question the error is indeed reported in the normal way:

<!-- Page Template Diagnostics
 Compilation failed
 TAL.TALDefs.TALError: Python expression error:
invalid syntax (line 1) in expression 'python:DateTime.Date(\r\nhere.end()\r\n)', at line 106, column 21
-->

Since the \r\n is in no way syntactically important in this case, I'd suggest that this is a bug.
