[kepler-users] SDF Firing Order

Hi,

 

In SDF if two actors have their input ports connected to a relation, what
determines which fires first?  Since the order may be important, is there a
way to insure the order you want.

 

In particular, the attached example, which uses a File Writer actor with the
fileName determined by a workspace parameter that is set by the same
relation that determines the File Writer input, does not work correctly
because the parameter is set after the File Writer fires.

 

Maybe there is a better way to specify a variable fileName to a File Writer
in the first place (in which case I would appreciate some guidance), but
this is not the only workflow in which I am having a firing-order problem.

 

Thanks,

 

        -Ken
