KeyPad showing up Secondary value rather than primary value

[Srikanthklkrn]

Hi All,I am really stuck with the issue.Any suggestion would be really helpful,

I am having a strange issue with Asha 201 in My app.
One of the screens in My app lists down all the text value and i have a search text on top of it.When I press a key, say I press G, the text box shows up 5(which is alternative value for G in the keypad).This happens only for the first character,The consecutive characters show up for watever the value is typed.i have implemented 'ItemstateChange' for this screen and checkin the state change for the search text bos.This App works fine on Nokia X2-02 and E63 and E5 also.

Any help would really great.

Regards,
Srikanth

Is it similar to this issue?

Hi Graham,
Not exactly to that issue.But it is similar. i have text labels dynamically populated and it looks like ItemstateChange method is called twice instead of once when i press a key.

From the other thread, it does sound like there are issues with TextFields on Series 40 devices with QWERTY keyboards, under certain circumstances.

Can you create the most minimal example of code that re-creates the issue?

Hi Graham,

I have recreated the scenario..Its somethin simialrto wat i am doin but this code doesn gimme the issue

but this code doesn gimme the issue

Sorry, you mean this code does not show the same problem that you see with your app?

You need some code that does show the same problem. This will give three benefits:

1. In doing so, you'll probably work out what causes the problem
2. You'll have an example other people can try
3. We'll have a simpler piece of code to help us figure out a workaround (if one exists)
