[JW Lua] Glissando metric pos calculation always returns false

[Jan Angermüller]

Jari,

the functions FCSmartShape:CalcLeftEntryMetricPos and 
CalcRightEntryMetricPos always return a false and no point calculation 
when the smartshape is an (entry-based) glissando.
Below you find the test code.

I was also experimenting with some metrics rebuild functions
( finale.FCEntryMetrics:MarkMetricsForRebuild() and 
finale.FCCellMetrics:MarkMetricsForRebuild() )
but always the same result: no calculation and a false-return.

It also doesn't matter if it is a JWLua-created glissando or a manually 
created glissando.

Best regards,
Jan

function GetEntryToSmartshape(id,measure,staff)
     local region=finale.FCMusicRegion()
     region.StartMeasure=measure-1
     if region.StartMeasure<1 then
        region.StartMeasure=1
     end
     region:SetStartMeasurePosLeft()
     region:SetEndMeasurePosRight()
     region.EndMeasure=measure
     region.StartStaff=staff
     region.EndStaff=staff

     for e in eachentry(region) do
        if (e.ENTNUM == id) then
            return e
        end
     end
     return nil,0
end

--finale.FCEntryMetrics:MarkMetricsForRebuild() --currently taken out as 
it made no difference
--finale.FCCellMetrics:MarkMetricsForRebuild()
