Bug ID: 92420
Summary: Use of a specific field after dispose: not working
anymore (it used to work)
Product: LibreOffice
Version: 4.4.0.0.alpha0+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: minor
Priority: medium
Component: BASIC
Assignee: [email protected]
Reporter: [email protected]

Basic example that works on LO 4.3 but not on 4.4
The behaviour of LibreOffice Basic changed in LO 4.4. The new behaviour might
make sense (I'm not a Basic expert) but some macros might rely on the previous
behavior.
Basically it can be summarized (see the attachment for a working example):
Set oRange = oMark.Anchor
' If oMark.dispose is not called: it works on LO 4.4
oMark.dispose
' Use oRange
oRange.text.insertTextContent(oRange, oField, true)
In LO 4.3 oRange is valid (even if oMark got disposed) (does it use a reference
counter and avoids destroying oMark?).
In LO 4.4 oRange is not valid and the last line causes an exception:
BASIC runtime error.
An exception occurred
Type: com.sun.star.lang.IllegalArgumentException
Message: first parameter invalid.
I'm not sure if this should have worked on LO 4.3 (and all the previous ones)
or was working due to a bug there.
We found it because a code like this exists in the Mendeley Desktop plugin:
https://github.com/Mendeley/openoffice-plugin/issues/16
Obviously I've simplified the code.
If this should not work I'll change MD code to avoid using the range of the
diposed mark (I might try to change our code anyway).
