I had the same problem, this is my solution:

@ManagedBean
@SessionScoped
public class DepartmentMB {
boolean createNewDepartment = false;
...
}
I want to have a <h:commandLink value="create new department" action="#{departmentMB.createNewDepartmentChange()}"/> that would only change the boolean value to opposite and according to it I would render or not a form.
<h:panelGroup rendered="#{departmentMB.createNewDepartment}">....</h:panelGroup>

this way it doesn't work:
//this is ok
private boolean createNewDepartment = false;
//this is ok
public boolean isCreateNewDepartment(){
return this.createNewDepartment;
}
//this is wrong
public void setCreateNewDepartmentChange(boolean b) {
createNewDepartment = !createNewDepartment;
}

Then I removed the parameter, the set and the first letter must be small.

public void createNewDepartmentChange() {
createNewDepartment = !createNewDepartment;
}
