Hi,
I have submitted a patch for review:
https://gerrit.libreoffice.org/4071
To pull it, you can do:
git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/71/4071/1
fdo#64279 do not crash opening report for editing
There are two problems:
1) The classes derived from SdrObject cache their SvxShape, but do not
implement impl_setUnoShape().
2) There is a lifetime issue in association of a SdrObject and its
SvxShape. SvxDrawPage::CreateSdrObject not only creates a new SdrObject
for a shape, but also inserts it into the page. At this point, the shape
has not been attached to the object yet. That means that the object
creates another shape at one point during the InsertObject call,
which is then destroyed again. But reportdesign shapes own their
objects, which means that destuction of the shape causes destruction
of the object too...
My first idea was to disable the insertion in
SvxDrawPage::CreateSdrObject, but it has been there since the dawn of
time, so I did not gather the courage to do that. Instead, I put in a
hack to allow to skip the insertion.
