[zope2-tracker] [Bug 1076316] Re: Tales Expression breakage in lates Zope 2.12.26 and 2.13.

[Andreas Elvers]

The current workaround is to write something like this:

<span tal:condition="exists:options/blah" tal:replace="string:${options/blah}"></span>
<span tal:condition="not:exists:options/blah" tal:replace="string:foo"></span>
