2666	NullOut instance has no attribute 'flush'	zalkind	Markus Pelkonen	"I tried this macros:
{{{
[[BurnDown(width=800,height=200,query=targetmilestone=milestone1&datestart=08/8/07&dateend=8/22/08)]]
}}}
{{{
[[BurnDown(width=400,height=200,query=targetmilestone=milestone1&datestart=08/8/07&dateend=8/15/08)]]
}}}
{{{
[[BurnDown(width=400,height=200,query=targetmilestone=milestone1&datestart=08/15/07&dateend=8/22/08)]]
}}}
{{{
[[BurnDown(width=600,height=200,query=targetmilestone=milestone1&dateend=8/31/08)]]
}}}

and with all of them i got this error:
