      Description



      Name: dk106046 Date: 07/07/2003

      java version "1.4.2-beta"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-beta-b19)
      Java HotSpot(TM) Client VM (build 1.4.2-beta-b19, mixed mode)

      (also 1.4.1, 1.3.1, 1.3.0)

      1. Setup Japanese input locale (add hotkey for locale)

      2. Run testcase
                java Test
        
      3. Type "a" then toggle the orientation using ctrl+shift+o, then type "b" and you'll see the text right justified.Toggle the orientation back to the left using ctrl+shift+o.

      4. Activate Japanese Hiragana using your hotkey

      5. Type "kanji".
         Japanese Hiragana string is shown as a preedit text.
         However, it is located at the next line. <----- *A
         And the cursor is located at the next line of the preedit text. <--- *A
         
      7. Press Enter to commit the text.
         Then the committed text is moved to the first line.
         
      8. Press Enter again to move the cursor to a new line.

      9. Type "kanji".
         Japanese Hiragana is shown as a preedit text.
         However it does not have underline, which means a preedit state. <--- *B

      Problem *A: Is this designed behavior? If so the behavior is very different from prior to the orientation toggle.
      Problem *B: This looks like a bug. Preedit text should definitely be underlined prior to being commited. Also the behavior differs from *A.

      All the commited text is correctly positioned. These problem are with preedit text.
