endEvent instead of end just get things worst :( If you know any template that works with interaction based on menu selection, please let me know. I'm so frustrated i'm just trying all possible combination without success. Thanks anyway -----Messaggio originale----- Da: Jack Jansen [mailto:[email protected]] Inviato: domenica 17 giugno 2007 0.48 A: ___ Cc: 'SMIL List' Oggetto: Re: Urgent please It is a bit difficult to read your code, but the problem may be that your mixing up scheduled end and event-based end. if bt_A.activateEvent is fired then two things happend immediately: 1. B_par ends 2. B_text2 ends You're expecting that the end of B_par raises B_par.end which in turn leads to B_text2 ending. This seems like a reasonable expectation, but I'm not 100% sure it is correct. "B_par.end" is different from "B_par.endEvent": the first one is scheduled and the second one is event-based. The exact distinction between those two mechanisms can be found in the SMIL standard (in the timing section), but the hand-waving explanation is that scheduled timing is pre-computed into the timegraph (similar to seq children starting when their predecessor ends, etc) whereas event-based timing happens on the fly (the timegraph is computed as if end="indefinite", I think). I'm not sure whether the standard specifies what should happen in this case (a scheduled timing relationship depending on an event-based timing relationship), maybe Sjoerd or someone else who understands this better than me can explain? But what I am sure of is that with a construct like this you're descending into the deep damp cellars of the SMIL timing model, so you're quite likely to stumble upon a bug. My suggestion would be to change the "B_par.end" into "B_par.endEvent", thereby making everything event-based, and hoping that that fixes the problem.

The difference between B_text1 and B_text2 is that the end differ in this way: B_text1 --> B_par_text1.end;bt_A.activateEvent B_text2 --> B_par_text1.end;B_par.end BUT, since B_par group has the end attribute set to: bt_A.activateEvent, shouldn't B_par.end and bt_A.activateEvent act the SAME way?
