30 Mar 31, 2008 DR:OMAPS00164541 - x0082844
31 Description: OTA ATT - GSM-BTR-1-5618 - MS wrongly displays long number stored in ADN
32 Solution:No need to check for the current chararcter, if its a space.
33
34 Feb 02, 2006 DR: OMAPS00061468 - x0035544.
35 Description: SAT 27.22.4.22.2 SET UP IDLE MODE TEXT (Icon support) fails
36 Solution : Modifications for displaying idle mode text and icon are done in
37 ATB_edit_OutTextLines.
38
39 Jan 16, 2006 DR: OMAPS00061460 - Shashi Shekar B.S.
40 Description: SAT Icon support
41 Solution : Modifications done in ATB_edit_OutTextLines
42 for display of the title icon.
43
44 CRR:25542 - xpradipg - 26 Oct 2004
45 Description: The last character is not deleted from the text entry screen in
46 any WAP page.
47 Solution: The formatIndex was set to zero on reaching the last character which
48 skips the removal of the last character. This assignment is moved out.
49
50 Jul 22,2004 CRR:21605 xrashmic - SASKEN
51 Description: After deleting all the characters in the editor the case does not change to
52 sentence case.
53 Fix: After deleting a character, check if editor is empty and then set the case to
54 sentence case only if the user has not modified the case.
