InDesign Applescript: "override master page items" glitch? - applescript

Question

Here's a very simple script that overrides all master page items on page 1:
tell application id "com.adobe.InDesign"
tell active document
override every item of master page items of page 1 destination page page 1
end tell
end tell
For some reason, this results in the page items shifting up and to the left of their original location. I cannot figure out why this is happening. Overriding page items should NEVER move the items. In fact, when I manually override in InDesign, nothing shifts. It appears to be affecting a specific layout. When I do a test document, the problem goes away. This particular document has many levels of master pages applied to each other, then applied to a layout.
Anyone else encountered this issue?

Answer 1

I encountered the same issue. This is my workaround:
set myPageRef to object reference of myPage
set myMPitems to master page items of myPageRef
if (count of myMPitems) > 0 then
repeat with myMPnumber from 1 to count of myMPitems
tell item myMPnumber of myMPitems
set temp_bounds to geometric bounds
set myOverridden_pageItem to override destination page myPageRef
tell myOverridden_pageItem
set geometric bounds to temp_bounds
try -- in case of an image
fit given center content
end try
end tell
end tell
end repeat
end if

This here worked for me https://forums.adobe.com/message/4294636#4294636 in cc2014
function main() {
var doc = app.activeDocument,
i, l, page, j, k;
for (i = 0, l = doc.pages.length; i < l; i++) {
page = doc.pages[i];
if (page.appliedMaster !== null) {
for (j = 0, k = page.appliedMaster.pageItems.length; j < k; j++) {
try {
page.appliedMaster.pageItems[j].override(page);
} catch(e) {}
}
}
page.pageItems.everyItem().detach();
}
}
if (app.documents.length > 0) {
app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, "Detach Master Page Items");
}

This works for me in CC 2018 (13.0.1) and Sierra 10.12.6:
tell application id "com.adobe.indesign"
tell document 1
repeat with i from 1 to count of pages
try
override (every item of master page items of page i whose allow overrides is true) destination page page i
on error
--
end try
end repeat
end tell
end tell
