[protege-owl] [SWRLTAB in protege 3.4.7]

hi everyone,

I'm testing the SWRL Tab on protege 3.4.7

I have create an ontology A in which i import the temporal so that i  
can use the temporal builtin in my ontology.

I have created the classes TimeEvent and elapsedTimeEvent as subclass  
of extendProposition

Then i have asserted TimeEvent(TimeEvent_1),  
hasValidTime(validInstant_1) , hastime(validInstant_1, somedate1),  
validInstant(validInstant_2), hastime(validInstant_2, somedate2)

However when i  write the folllowing rule:

TimeEvent(?x) ∧ p1:hasValidTime(?x, ?vt1) ∧ p1:before(?vt1,  
ValidInstant_2) → elapsedTimeEvent(?x)

It doesn't work. I have an error that says : cannot convert  
DefaultSWRLImpl(rule1 of [DefaultOWLNamedCLASS( 

Does any one has an idea of what might be the problem ?

Many thanks,
in advance
