Hi Per,
So happy to see you again. There are something that need talk with you.
First I will re-open JBPM-2795 and provide a new patch later. Thank you for point out that.
Second, I want to ask you some help for some JIRA issue, if you have time, please have a look at these.
1. https://jira.jboss.org/browse/JBPM-2813, You notice that there is a patch, but I cannot find it. could you re-upload this patch again?
2. https://jira.jboss.org/browse/JBPM-2814, I marked this issue as 'Incomplete Description', because I didn't know what you want to do with custom business calendar, Could you give me some more information about these?
