setting outputformat on the fly (phpmapscript)

[Nicol Hermann]

Dear developers,

i like to set the outputformat of an imagemap with PHP mapscript on the
fly. To do so i use the following code:

$map->outputformat->set("name","imagemap");
$map->outputformat->set("mimetype", "text/html");
$map->outputformat->set("driver", "imagemap");
$map->outputformat->set("extension", "html");
$map->outputformat->setOption("formatoption", "MAPNAME=imap");
$map->outputformat->setOption("formatoption", "POLYHREF=%s");

All i get back is the following output:

<map name="(null)" width="300" height="300">
p—/,
</map>       </FORM>

I assume this a bug, right? Does this have something to do with bug
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=979 or should i fill a
new one?

Many thanks
Nicol
