XML exception when calling ITCMLocalLBVirtualServer.get_virtual_address_list()

I'm writing some iControl code (using iControl 4.6.2) for use against a

 

540 running 4.5.9 Build 2 and a 2400 running 4.5 PTF3. When I call

 

ITCMLocalLBVirtualServer.get_virtual_address_list() from the 540, I get the following exception (XML error), but the same code works from the 2400. Is there a known bug in 4.5.9 Build 2? I looked through the release notes for later releases but didn't find any references to this problem.

 

 

TIA.

 

 

System.InvalidOperationException: There is an error in XML document (11,

 

2). ---> System.InvalidOperationException: The specified type was not

 

recognized: name='ITCMCommon.IPAddress', namespace='urn:iControl', at xmlns=''>.
