Bug ID: 66284
Summary: Apache POI - Merge deck with different slide layouts
Product: POI
Version: unspecified
Hardware: PC
Status: NEW
Severity: critical
Priority: P2
Component: XSLF
Assignee: dev@poi.apache.org
Reporter: jatish.kha...@gmail.com
Target Milestone: ---
On Using option targetDeck.createSlide(srcSlide.getSlideLayout), the apache POI
throws error while writing (mergedDeck.write(outStream)) to a deck -
Rule M2.4 exception : Part '/_rels/.rels' not found - this error should NEVER
happen!\nCheck that your code is closing the open resources in the correct
order prior to filing a bug report.\nIf you can provide the triggering file,
then please raise a bug at
https://bz.apache.org/bugzilla/enter_bug.cgi?product=POI and attach the file
that triggers it, thanks!
The probable reason for the above -
When slides are created using PackagePart with the same name in this case
(SlideLayout from different decks having different), on cleanup it will throw
an exception. Find below the trace-
