ISSUE

Following the upgrade of liferay and using the plugin Kaleo, when using the flow "Single approver" for Web Content and believe these tasks are not shown in "My Workflow Tasks" and throws a error log "My Submissions" when we try enter a task.

STEPS TO REPRODUCE

1. Install "liferay-portal-6.0-ee-sp2-20110727.war" on Jboss 5.1
2. Deploy Kaleo "Kaleo-web-6.0.12.1.war"
3. Go to Control Panel "WorkFlow Configuration" assign "Single Approver" to Web Content
4. Go to "Web Content" create content, should be no problems to see in "My Workflow Tasks" and "My Submissions"
5. Make upgrate of Liferay Portal Liferay Portal 6.1.2 to 6.0.12 ("liferay-portal-1.6.20-ee-GA2-20120731110418084.war")
6. Deploy Kaleo "Kaleo-web-6.1.20.1.war"
7. Go to Control Panel in "Workflow Configuration" assign "Single Approver" to Web Content
8. Go to "Web Content" create content
9. Go to "My Workflow Tasks" here are not new tasks created, just old tasks of Version 6.0 (First Issue)
10. Go to "My Submissions" here we can see tasks, but when try to enter each throws the .txt attachment error (Second Issue)
