Description Dani Megert CLA 2005-01-17 11:52:47 EST 
I20050112-1200

The overview ruler preferences (UI) for Text and JDT editor have been removed.
This can result in lost overview ruler if the text editor preference has been
set to false.

would be good to have for M5

The preference still exists in code, but is not surfaced to the user.

The solution is to add migration code that checks once per workspace whether the
preference is off and then re-enables it. Once that check has been made, set
another preference that the migration has happened, so that if a geek tool
manipulates the preference later, it does not get modified by the migration code
any more.

Dani, please verify.
Comment 4 Dani Megert CLA 2005-02-10 04:28:31 EST 
Verified in code ==> OK.

Verified the following scenario:
1. started 3.0
2. disabled overview ruler for text editor
3. started 3.1 without fix
   ==> no overview ruler in text and Java editor
4. started 3.1 with fix
   ==> overview ruler in text and Java editor
