Plone 4.3.3 and Chameleon engine (five.pt)

Development Developing for Plone
1

Hello Community,

we started using Chameleon engine (or just five.pt) recently. I already knew, that Chameleon is a bit stricter in terms of parsing TAL, but I recently stumbled on a problem, which should be no problem under my impression.

In short, this particular snippet is working, where as the other is not:

<!-- Works -->
<tal:content tal:define="foo string:bar;">
</tal:content>

<!-- Works not -->
<tal:content
tal:define="foo string:bar;">
</tal:content>

Both cases should be valid xhtml, right? The latter moved the attribute into the next line and I get the exception message "unexpected end tag".

I this an issue between five.pt and Plone 4.3.3 or due to the new "strictness" introduced with five.pt?

best regards, Paul

is this working?

<tal:content
 tal:define="foo string:bar;">

Note the space before tal:define, your example is one string <tal:contenttal:define= etc

3

Sadly, I get the same result even with those spaces before tal:define. I also used other tags like span.

4

So this is failing? when using span

<span
 tal:define="foo string:bar;" />
5

Yes.

6

Can you post your full error log?

7

I will post more tomorrow.

I was trying to create a minimal example to demonstrate that bug. But it does seem to work. Seems I need to investigate closer here. However, here is the error log:

As a side node: Could it be, that "translate" cant be overriden in chameleon? See minimal example and stacktrace here: http://pastie.org/private/gzqxbugtyva7ssqg2qw6lq

i18n:translate so yes please use something other then translate

Follow up: The problem seems to be occuring when using windows line endings (CLRF). When using LF, the very same template works like a charm.
