 a common difficulty when using mapagent is the obscure error messages
 returned like

 "The value cannot be less than or equal to zero." with out the actual
 missing parameter being shown in the error message

 this is often seen when using the web tier tests

 a quick search

 http://www.google.com/codesearch?q=MgValueCannotBeLessThanOrEqualToZero&hl=en&btnG=Search+Code

 show this is a common error and occurs for times in the Rendering service

 http://trac.osgeo.org/mapguide/browser/trunk/MgDev/Server/src/Services/Rendering/ServerRenderingService.cpp#L262

 this makes using the mapagent really frustrating, copying and comparing
 urls to debug isn't fun
