[JW Lua] FCBeatChartElement(s) - Problems with v0.66

[Jan Angermüller]

Robert,

in my further tests with v0.66 and Perfect Layout I noticed that the 
*FCBeatChartElement *functionality has changed significantly.
My "insert space" function doesn't work anymore ... while it used to add 
more space, it now reduces the space in some cases.

Attached is a test document and a code snippet.
However, the problem occurs in all sorts of documents.

The code simply prints the FCBeatChartElement properties from measure 4.
It seems that there is a problem with the MinimumPosition on 
FCBeatChartElement 0.

function plugindef()
    finaleplugin.LoadLuaSocket=true
    return "Test","Test","Test"
end
pluginname=plugindef()
if finenv.IsRGPLua then require('mobdebug').start() end
local measure=finale.FCMeasure()
measure:Load(4)
local beatcharts= measure:CreateBeatChartElements()
local beatchart2
for beatchart2 in each(beatcharts) do
print("BC2",measure.ItemNo,beatchart2.ItemCmper,beatchart2.ItemInci,beatchart2.MeasurePos,beatchart2.HorizontalPosition,beatchart2.NextHorizontalPosition,beatchart2:CalcWidth(),beatchart2.MinimumPosition)
end

Before RGP Lua v0.66   (here JW Lua 0.54)
BC2 4 4 0 4096 336 0 0*641*
BC2 4 4 1 0 0 84 84 0
BC2 4 4 2 1024 84 116 32 64
BC2 4 4 3 1280 116 148 32 125
BC2 4 4 4 1536 148 200 52 177
BC2 4 4 5 2048 200 336 136 218

RGP Lua v0.66
"BC2"    4    4    0    4096    336    0    0 *0* -- 641 missing!
"BC2"    4    4    1    0    0    84    84    0
"BC2"    4    4    2    1024    84    116    32    64
"BC2"    4    4    3    1280    116    148    32    125
"BC2"    4    4    4    1536    148    200    52    177
"BC2"    4    4    5    2048    200    336    136    218

Any ideas?
