everything moved to jsf UI components. see jbpm4jsf subproject in the sources
So I have to modify all managed-beans like jsf UI components and make them similar to jbpm4jsf sources?
But I think <managed-bean> tag is the feature of JSF. How and why was it removed?
I made a stupid mistak by puting tags <managed-bean> in the scope of !
Now, it is working well.
