Maybe a static RGP Lua function with the content below that one can
add to the end of a Lua script?<br>
<br>
Then you don't have to add this function below to your own code.<br>
<br>
Finally, add a reminder to the SetWidth documentation. Something
like:<br>
"When using SetWidth in linked parts, make sure to add the static
... function to the end of your Lua script. <br>
It will maintain the correct measure width in the score when calling
undo and then redo after applying the plug-in."<br>

<div>Steve, I believe you have my plugins. I always make a copy
of my score before beginning the parts layout. I can then copy
the measure widths and spacing from my score copy back to the
score using Mass Copy as needed. (I tend to need it.) But I am
going to add Jan's workaround to the Note Spacing plugin, and
that could possibly eliminate the need to do this, provided I
always use the Note Spacing plugin for spacing (which I do).<br>

<div>Jan, describe the direct support in RGP Lua you are
imagining. I am not eager to add it to "SetWidth" on
FCMeasure, because who knows what it might do in future Finale
release. Plus, Jari seems to have kept the properties pretty
clean as straight pass-thrus to PDK structs. (I have been a
little lax in that, but mostly I try to follow the pattern.)</div>

<div> I can now confirm that the workaround seems to solve the
measure width undo/redo problem in Perfect Layout. I have
also added the code to another plug-in and it fixed the
problem too.<br>
<br>
Probably it makes sense to add this code to all plug-ins
that change the measure width in parts.<br>
Maybe it makes sense to even support this directly through
RGP Lua?<br>
<br>
Below is the full code that I used.<br>
<br>
Robert, I was wondering about one thing:<br>
according to my notes changing the FCMeasure object works
best when the part has the focus with part:ViewInDocument().<br>
In a first attempt I had also added p:ViewInDocument() to my
code below when the plug-in was applied to the part only and
the measure width had to be corrected in the invisible score
(see commented line below).<br>
However, the workaround also worked fine when I removed
ViewInDocument.<br>
Is FCMeasure safe without ViewInDocument? <br>
Or is it because of the Finale bug that this weird
workaround even works without ViewInDocument?<br>

<div> Thank you for the quick response, Robert!<br>
I found a workaround which at least works in the
test case below:<br>
When I (re-)save the measure width in the score
afterwards, it is still the same bug.<br>
BUT:<br>
When I slightly change the measure width in the
score, save it, then restore the original value and
save it again, both the measure width in the score
and in the parts seem to have the correct value.<br>
It seems to set a flag in Finale that the measure
width in the score has indeed changed.<br>
<br>
I will have to check if this also solves the problem
in Perfect Layout.<br>
<br>
Here is the new test code with the additional lines
in bold:<br>
<br>
--Show measure 1 width from score<br>
local meas=finale.FCMeasure(1)<br>
meas:Load(1)<br>
print("Measure Width in Score",meas.Width)<br>
<br>
--Load Part 3 and change<br>
local p=finale.FCPart(3)<br>
p:SwitchTo(); <br>
p:ViewInDocument()<br>
meas=finale.FCMeasure(1)<br>
meas:Load(1)<br>
print("Measure Width in Part ",p.ID,meas.Width)<br>
meas.Width=360<br>
meas:Save()<br>
print("Measure Width after change",meas.Width)<br>
p:SwitchBack(); <br>
<br>
--Go back to score and show measure 1 width<br>
p=finale.FCPart(0)<br>
p:ViewInDocument()<br>
meas=finale.FCMeasure(1)<br>

I have noticed several times that undo-ing
and re-doing a JW Lua plug-in can change the
measure width.<br>
Finally, I have created a short
reproduceable demo that I can't explain.<br>
<br>
The script is below.<br>
When applied to the score of the attached
Finale file, it switches to linked part 3,
loads measure 1 and changes its measure
width to 360 and then returns to the score.<br>
The measure width in the score remains
unchanged. So far, everything ok.<br>
Then I undo the plug-in in Finale and click
on Edit->Redo ...<br>
Now the width in measure 1 also changes in
the score!<br>
<br>
Here is a video that shows the effect (with
a slightly different version of the score):<br>

moz-do-not-send="true"
class="moz-txt-link-freetext">https://www.youtube.com/watch?v=lPJd3sq9zQg</a><br>
<br>
In Perfect Layout it makes Finale's
Undo-/Redo feature unusuable, because it
(nearly) always changes the measure widths
in the score for an unknown reason.<br>
Do you have an idea how I can prevent this?<br>
