i18n directive interferes with py:if expression

[hoff.st@…]

I want to exclude a 'span' HTML element, if value=0. This is the minimized template markup for this use case:

<label i18n:msg="timedelta">
  Duration:
  <input type="text" name="input"
         value="$value" />
  seconds
  <span py:if="value">
    (${fmt_value(value)})
  </span>
</label>

I've added the i18n directive to get a msgid like

'Duration: [1:] seconds [2:](%(timedelta)s[3:]'

instead of split msgids 'Duration:', 'seconds', ...).

But with value=0 the py:if directive seems ineffective:

<label>Duration:
  <input type="text" name="input" value="0" />
  seconds
  <span>
    ()
  </span></label>

The 'span' element is included regardless of the value of 'value'.

Simply removing the i18n directive like

<label>
  Duration:
  <input type="text" name="input"
         value="$value" />
  seconds
  <span py:if="value">
    (${fmt_value(value)})
  </span>
</label>

fixes this:

<label>Duration:
  <input type="text" name="input" value="0" />
  seconds
</label>

'span' disappears correctly, if value=0. If not for the braces I wouldn't have noticed this nor would I care.

Maybe there is a related issue in the Internationalization domain: When the py:if directive would strip the 'span' element successfully, the expression i18n:msg="timedelta" would become invalid. Not sure, if that would hurt on template rendering time.

Are you using the latest 0.6.x version from svn or the 0.6.0 release? If you're not using the latest 0.6.x could you try that? I think some related bugs were fixed in svn awhile ago.

I've been using Trac dependencies for most of my test environments, so this should be equal to genshi-0.6 release as I guess.

Thanks for the hint on fixes in 0.6.x. I'll have to setup another test environment with focus on latest Genshi code. Hope to report my findings soon.
