Jasper & Groovy errors after migraation
I'm migration to 7.3.3 bonita to last one 7.11 and after the upgrade I detect 2 errors.
The first one is that in the new version there is no jasper connector library, I think this one is easy to fix but the second one is that one groovy script is failing.
groovy.lang.MissingMethodException: No signature of method: java.sql.Timestamp.toDate () is applicable for argument types: () values: 
Possible solutions: getDate (), setDate (int), updated (java.util.Map), format (java.lang.String), isCase (java.lang.Object), format (java.lang.String, java.util .TimeZone)
I understand the error but my question is more focused on understand how I should handle this migration error types?? Should I change the xml diagram directly???
Thank you very much
