Description

my working sub element:

 
<entity name="jobexperience" 
	pk="ID"
	query="select * from jobexperience je where je.PROFESSIONAL_ID = '${user.USERID_FT}'"
	deltaQuery="select je.ID as ID from jobexperience je where je.LASTMODIFIEDDATE > '${dataimporter.last_index_time}'"
	parentDeltaQuery="select je.PROFESSIONAL_ID as ID from jobexperience je where je.ID=${jobexperience.ID}" 
/>

my failing sub element (resulting in NullPointerException):

 
<entity name="jobexperience"
	query="select * from jobexperience je where je.PROFESSIONAL_ID = '${user.USERID_FT}'"
	deltaQuery="select je.ID as ID from jobexperience je where je.LASTMODIFIEDDATE > '${dataimporter.last_index_time}'"
	parentDeltaQuery="select je.PROFESSIONAL_ID as ID from jobexperience je where je.ID=${jobexperience.ID}" 
/>
