Build Identifier: stem.buildId=1.1.1RC4.M20110122

Trying to create scenarios and models by using components of existing
stem example scenarios and trying to understand the structure of stem 
simulations, I have tried to import existing stem scenarios into freshly
created stem projects into the scenario section, to reuse and rearrange
the already defined components.


An exception occurred invoking extension: org.eclipse.stem.ui.views.explorer.identifiables2 for object org.eclipse.jface.viewers.TreePath@6a3088e8


java.lang.ClassCastException: org.eclipse.stem.core.scenario.impl.ScenarioImpl cannot be cast to org.eclipse.stem.core.sequencer.Sequencer
	at org.eclipse.stem.core.scenario.impl.ScenarioImpl.getSequencer(Unknown Source)
	at org.eclipse.stem.core.scenario.impl.ScenarioImpl.eGet(Unknown Source)

.<etc>
.<complete stacktrace not included for brevity!>

Reproducible: Always

Steps to Reproduce:
1.Create fresh stem project
2.verify validity of stem example scenario ARG(Level: 2) Influenca,... by starting+stopping it again 
3.Drag scenario ARG(Level: 2) Influenca,... from Resources into the scenarios
section section of the fresh project
4.Receive error about Sequencer
