Could this be a problem with an incorrect template and/or 
template-elements property for the xml file that you try to include? 
Make sure that both of these properties are present and correctly set.

Also, please try to see, if cmsJSPActionElement.include will REALLY work 
for the exact same file that you have problems with when using the 
cms:include tag. Normally, either both ways should work or both ways 
should fail.
