    Description

    Basically the problem is:

    
class Zend_Exception extends Exception
{
    private $_previous = null;
}

class Zend_Db_Adapter_Exception extends Zend_Db_Exception
{
    public function hasChainedException()
    {
        return ($this->_previous !== null);
    }
}

    I can imagine that either:

    1) {{Zend_Db_Adapter_Exception::hasChainedException}} should call {{Zend_Exception::getPrevious()}} instead of reading the missing private property 2) or {{Zend_Exception::$_previous}} should be declared protected 3) or {{Zend_Db_Adapter_Exception::hasChainedException()}} should be moved to {{Zend_Exception}}

    I checked and this does not seem to be fixed in 1.11.12
