Vladimir Gorej commented on LOG4PHP-150:
----------------------------------------
Hello again,
What error exactly are you getting ?
This code fragment should not be executed in PHP 5.2.
This statement checks the Exception API for exception chain support and
if it's not supported, it is simply not executed.
if (method_exists($o, 'getPrevious') && $o->getPrevious() !== null)
> getPrevious ObjectMethod being used but does not exist in the code

> In renderers/LoggerRendererException.php line 34, a call is made to
> $o->getPrevious() whereas this method does not exist. I assume $o is an
> object for LoggerLoggingEvent which does not contain this function.
> I did a search on the trunk as well and did not find this function defined
> anywhere.
