[RavenclawDev 233] Re: accessing history of concepts from ravenclaw

[Svetlana Stenchikova]

Thanks Antoine. I am sorry to bother you guys with my questions. I
know everyone is busy. I hope everything is going well.


The RESETS in my application were inherited from the roomline. When I
replaced all RESETS with REOPEN, it broke some functionality. For
example, when the confirm agent is entered the second time, it does
not get executed. I assume its because confiration_result does not get
reset.
Even though I explicitly reopen it:
			REOPEN_CONCEPT(/RavenCalendar/Task/TaskRemoveEvents/Confirm/confirmation_result)		C("/RavenCalendar/Task/TaskRemoveEvents/Confirm/confirmation_result").ClearExplicitlyConfirmedHyp();
	    C("/RavenCalendar/Task/TaskRemoveEvents/Confirm/confirmation_result").ClearExplicitlyDisconfirmedHyp();


Is the functionality of Reopen complete?

Also, I see some calls to Clone(false) in the Concept.cpp. Wouldn't
that erase the history?


Thank you,
Svetlana

the confirm agent:


DEFINE_REQUEST_AGENT( CConfirm,
    REQUEST_CONCEPT(confirmation_result)
	DEFINE_CONCEPTS(BOOL_USER_CONCEPT(confirmation_result, "expl"))
	INPUT_LINE_CONFIGURATION("set_grammar=toplevel")
    PROMPT(":non-interruptable request confirm_operation
operation_type<operation_type event<eventlistresult.0")
    GRAMMAR_MAPPING("[yes]>true, [no]>false, [Quit]>false")
    SUCCEEDS_WHEN(AVAILABLE(confirmation_result) &&
UPDATED(confirmation_result)
		&& C("confirmation_result") == CBool(true))
    FAILS_WHEN(AVAILABLE(confirmation_result) && UPDATED(confirmation_result)
		&& C("confirmation_result") == CBool(false))
