Android keyboard type automactially changing

Hi,

I am facing a strange problem in Samsung Galaxy S2 and S3. If I click on a text field, the keyboard type first appears as decimal (which is what I have set to) and then automatically changes to Ascii.

On debugging I found that the textfield is getting a "focus" event and then immediately a "blur" event. The following log also appears in logcat when the keyboard type changes:

I/LatinIME( 145): InputType.TYPE_NULL is specified W/LatinIME( 145): Unexpected input class: inputType=0x00000000 imeOptions=0x00000000

I am using SDK 3.0.2GA but checked that the problem happens also on SDK 3.1.0GA.
