[PATCH] Change in core[libreoffice-4-0]: fdo#58562: Ensure internal data is always used when pasting ...

[Kohei Yoshida (via Code Review)]

Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/1835

To pull it, you can do:

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/35/1835/1

fdo#58562: Ensure internal data is always used when pasting to another doc.

Without this, pasting a chart object from one Calc doc to another may
occasionally incorrectly switch to range references *if* the destination
document contains the "right" set of sheet names.  With this fix, pasted
chart objects always switch to internal cached data source when pasting
to another document, while retaining range references when pasting within
the same document.
