Description Frank Schönheit 2004-10-13 15:45:55 UTC
- save the attached database and dBase file to an arbitrary location
- open the database file, adjust it's settings (Edit|Database|Properties) so
that it points to
  the proper location of the .dbf file
- The dBase table contains a text and a memo field
- create a simple form bound to the table, with one single line and one multi
line text field,
  both to both the two table columns
- open the form document for data entry
- open the attached text.txt, copy it's whole content to the clipboard
- place the cursor in the multi line text control of the form, and chose "Paste"
from the
  context menu
=> assertion: Overflowing rtl::OUString -> UniString cut to zero
=> the text is not pasted

Comment 6 Frank Schönheit 2004-10-13 15:57:15 UTC
- memo.odb is the database file
- memo.dbf is the dBase file
- contains memo.odb, memo.dbf, and memo.dbt (the memo file belonging
  to memo.dbf)
- text.txt contains a sample text to copy'n'paste to the memo control (I suppose
  every other  text does it, too)
- memo.oot contains a sample form. You may need to adjust it's settings to point
  to the database file

update: all the hassle with binding the control to a memo field is not
necessary: simply create a multi line text field, and paste the attached
text.txt's content into it.
Comment 8 Frank Schönheit 2004-10-19 15:30:32 UTC
adjusting summary: The problem is that the underlying TextView implementation
uses the tools/String class, which itself can not work with strings longer than
64K. A Paste operation into the TextView requires (for an intermediate step) a
single string which contains the whole text, so pasting fails when the string is
longer than 64K.

- some more sophisticated code in pasting, which breaks up the pasted string
(which originally is a ::rtl::OUString, which can be longer than 64K) into pieces.
- replace all occurences of String in the TextView/TextEngine class with

The latter is the better solution, but also much more expensive. Given that this
issue is in the product for quite a while, and we're close to a 2.0 Beta, I
re-target this to "OOo Later"
