Class ProcessInstanceInfo

public class ProcessInstanceInfo
extends Object

This is the object that contains the marshalled byte stream of information representing the ProcessInstance class. Because of Hibernate 3.3.x/3.4.x <-> 4.x compatibility issues, the mapping for this class has been moved to

Method Detail

getProcessInstanceId

public Long getProcessInstanceId()

Added in order to satisfy Hibernate AND the JBPMorm.xml:

• Hibernate needs getter/setters for a the field that's mapped.
  • (field access is inefficient/dangerous, and not necessary)
• The JBPMorm.xml queries reference .processInstanceId as well.

If we mapped the field using 'name="id"', the queries would thus fail.

So instead of that, we just add the getters and use 'name="processInstanceId"'.

Returns:

The processInstanceId field value.

setProcessInstanceId

public void setProcessInstanceId(Long processInstanceId)

getId

public Long getId()

setId

public void setId(Long processInstanceId)

getProcessId

public String getProcessId()

getStartDate

public Date getStartDate()

getLastModificationDate

public Date getLastModificationDate()

getLastReadDate

public Date getLastReadDate()

updateLastReadDate

public void updateLastReadDate()

getState

public int getState()

getProcessInstance

public ProcessInstance getProcessInstance(org.drools.common.InternalKnowledgeRuntime kruntime,
                                          Environment env)

update

public void update()

Adding @PrePersist breaks things, because:

• We retrieve/generate the marshaller (see below).
• ..and the marshaller retrieves the context instance
• ..which actually (re)sets all variables in VariableScopeInstance.setContextInstanceContainer(...)
• This of course causes ProcessEventSupport.fireBeforeVariableChanged(...) to fire.
• Then the JPAWorkingMemoryDbLogger ends up logging a variable change -- but the associated process instance hasn't been persisted yet.
• So the variable instance change is associated with process instance "0"
• ...and can never be retrieved, because "0" is not a valid id.

Normally, the variable change is logged after the following method has completed.
