WCM Metadata extraction [SOLVED]

[steventux]

I'm getting integrity violations having activated WCM Metadata extraction. I've verified this is the cause by testing on another build.
I'm sure something in my configuration must be causing this but the error is thrown when creating web content (regardless of type)
The errors don't immediately point to anything in my config.

So parentrenditionproperties, parentrenderingenginetemplate, primaryforminstancedata, parentformname sound fairly crucial properties to me  :idea:

[SOLVED]
The errors were caused by a freemarker coding error in the rendition template, nice and intuitive error message then  :shock:
I suppose there was a hint in the error message as it seemed only to complain about jsp files - i.e. the output from the template
