The error message is: {{{ Could not find variable at start of "" }}} I traced the error to the {{{__init__}}} method of {{{FilterExpression}}}. The attached diff fixes the error. I think some of the surrounding {{{if <var>}}} statements should also be rewritten as {{{if <var> is not None}}}, but the diff is restricted to fixing this bug. | nobody | jcassee | 0 | 1 | 0 | 0 | 0 | 0 |
