How to resolve this issue "java.lang.String cannot be cast to org.jbpm.task.utils.MarshalledContentWrapper"

[shahdhaval2020]

Hi all,

I am trying a human task example with variables , and i am using this link as a refrence https://community.jboss.org/people/bpmn2user/blog/2011/02/21/jbpm5-example-for-forms-with-variables

But now the thing is that when i am trying to run this i am getting following error.

I am using JBPM5.4 .

Exception in thread "Thread-2" java.lang.ClassCastException: java.lang.String cannot be cast to org.jbpm.task.utils.MarshalledContentWrapper

          at org.jbpm.task.utils.ContentMarshallerHelper.unmarshall(ContentMarshallerHelper.java:157)

I have a similar issue, except when using Integer variables in the designer and the auto-generated task forms.  In the link https://issues.jboss.org/browse/JBPM-3779 they mention a similar issue and say it was fixed for the JBPM 5.4 release, but I am currently using it an it is not working.  I wonder if the two problems are related.
