Hi Rajesh,
As we can see in the project drools-core, you can find the definition of the Email WorkItem :
[
"name" : "Email",
"parameters" : [
"From" : new StringDataType(),
"To" : new StringDataType(),
"Subject" : new StringDataType(),
"Body" : new StringDataType()
],
"displayName" : "Email",
"icon" : "icons/import_statement.gif",
"customEditor" : "org.drools.eclipse.flow.common.editor.editpart.work.EmailCustomEditor"
],
There is no parameter for CC / BBC.
But you can easily create your own WorkItem with this documentation : http://docs.jboss.org/jbpm/v5.4/userguide/ch.domain-specific-processes.html
Regards,
Nicolas.
