Missing ConfigurationRef Element
If you attempt to propagate the changes suggested by the Windchill Configuration Assistant but have not added the ConfigurationRef element to the site.xconf file, the build fails at the point where the ant script attempts to locate the element.
* 
Any intermediate properties files updated from all successful internal target runs that were completed prior to the propagation attempt remain. For example, assume that the propagation is attempted when running the configureWindchill target. Then the intermediate properties files generated before the build failure are not deleted.
An error similar to the following identifies the failure:
ERROR: site.xconf has no ConfigurationRef to
<Windchilll>/utilities/wca/conf/windchill/windchillconfigurator.xconf
To recover from this failure, you can add the ConfigurationRef element to site.xconf as described in Targets for the site.xconf ConfigurationRef Element and then run a target that propagates values as described in Targets for Propagating Values from Intermediate Files.
