trouble with lu_action

I am having trouble getting lu_actions to work from a web browser

the following works:

http://172.16.10.180:49451/data_request?id=lu_action&output_format=xml&DeviceNum=9&serviceId=urn:upnp-org:serviceId:SwitchPower1&action=SetTarget&newTargetValue=1

turning a dimmer all the way on.

but

attempts to turn the dimmer on at 50%

this does not work:

http://172.16.10.180:49451/data_request?id=lu_action&output_format=xml&DeviceNum=9&serviceId=urn:upnp-org:serviceId:Dimming1&action=SetLoadLevelTarget&newLoadLevelTargetValue=50

and gives the error
ERROR: Device does not handle service/action

any help would be appreciated.

newLoadLevelTarget

No the error still exist with that mod.

ERROR: Device does not handle service/action

but I found a workaround. I installed the iphone luup plug-in and found a url for dimming. It works fine
with my UI for dimming the lights. I think there is a bug and MCV needs to fix it. I am not sure how to
post a bug report, but it does not work

Here is the command that works when the iphone plugin is installed.

the_url = 'http://172.16.10.180/port_49451/data_request?id=lr_sPhone_action&room=1&device=9&service=urn:upnp-org:serviceId:Dimming1&action=SetLoadLevelTarget&newLoadlevelTarget=50’&time=1.25’;
