This error means that a DELETE for a record in JBPM4_LOB conflicts with a record in JBPM4_VARIABLE that points to that same record. I think this problem is related with this strange situation. The LOB_ in question is 2260042 (see next line). org.zkoss.zk.ui.UiException: rendering.0010: org.hibernate.exception.ConstraintViolationException: could not delete: [org.jbpm.pvm.internal.lob.Lob#2260042]. So I did a query on JBPM4_VARIABLE for any records with that LOB_. *select * from jbpm4_variable where lob_ is not null and lob_ = 2260229* And I got two records that: * use *ser-bytes* converter; * have two diferent *KEY_* names; * have two different *EXECUTIONID_* values; * Point to the same *LOB_*. Oddly enough the *EXECUTIONID_* values are for different processes. *select dbid_, procdefid_ from jbpm4_execution where dbid_ in (2260197, 2260223)* For setting a variable value we always use several API, but all from publicly exposed jBPM interfaces: * OpenExecution.setVariable(...); * ActivityExecution.setVariable(...); * ExecutionService.setVariable(...); So, to make my questions clear. Is this behavior normal for JBPM4_VARIABLE, I would have guessed it is not? And, what could be causing this strange behavior? Feel free to ask any more input, data that you consider could help investigating further this issue. -- Jorge -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/548684#548684] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
