nokia sets doesn't allow editing textfield

[saqib_ch]

Hi,
I ve the following code which is running well on emulators (wtk)
symbol = new TextField("Symbol","",20,TextField.ANY ) ;
price = new TextField("Price ","",20,TextField.DECIMAL ) ;
this.setItemStateListener(this) ;

public void itemStateChanged(Item item){
/* equalStrings my own written method which is implementation
of equalIqnorCase of String class because in CLDC1.0 equalIqnoreCase is not available*/
if(this.equalSrings(item.getLabel(),"Symbol" ) )
{
setPrice();
}
}

public void setPrice()
{
String temp = symbol.getString() ;
for (int i=0 ; i < symbols.length ; i++ ) {
if(symbols == null)
{
continue;
}
if(this.equalStrings(symbols.toString() ,temp) )
{
price.setString(prices.toString());

}
}
}
This is very straight forward code where symbol array contains symbols and if something entered in symbol text field match with any of these symbols its price from price array pop up in price text field
Now it works fine on emulator but when it deployed it on any nokia set
the last character of symbol does not appear although event fired and price is set in price field
so i entered a line in setPrice() method
symbol.setString(symbols );
now symbol is displayed in symbol field but it becomes uneditable in nokia sets . It is working fine in Sony/Erricson sets and emulator(wtk)
can any one tell me what is the problem ?????

You seem to be using CLDC 1.0 device (which one?) as you mentioned implementing some methods missing from CLDC 1.0. There is no support for floating point numbers in CLDC devices and possibly TextField.DECIMAL does not work properly on those devices (even if they might support MIDP2). Are you building the app also for CLDC 1.0 devices (you have to select a CLDC 1.0 specific option in WTK)? Have you tried using some other TextField constraing on the problemtaic field?

Imo, it has nothing to do with TextField.DECIMAL as it is a problem with the the other textfield.

When you say symbol, are they normal letters of the alphabet (eg. arb) or are they actually symbols (eg. $ % ^)? Also, which nokia handsets are you testing on? S60?

Also, in the for loop below, you forgot to add the [i] and instead reffered to the main array itself.

symbol = new TextField("Symbol","",20,TextField.ANY );
price = new TextField("Price ","",20,TextField.DECIMAL );
this.setItemStateListener(this) ;

public void itemStateChanged(Item item){
 if(this.equalStrings(item.getLabel(),"Symbol" ) ) {
   setPrice();
 }
}

public void setPrice(){
 String temp = symbol.getString() ;
 for (int i=0 ; i < symbols.length ; i++ ) {
   if(symbols[i] == null) {
    continue;
   }
   if(this.equalStrings(symbols[i].toString() ,temp) ) {
    price.setString(prices.toString());
   }
 }
}

PS: I just realized...

so i entered a line in setPrice() method
symbol.setString(symbols );

If the above wasn't a typo, perhaps doing this will solve your problem:
symbol.setString(symbols[i]);

Thanx all 4 replying

Actually this wasnt the prob which u guys pointed

Actually i ve used symbols[i] istead of price[i] instead of price

the problem was with event handling . I ve solved the prob so

here i m trying to explain it
when we press any key and focus was on symbol text field "setPrice()"
called and once it set the price it was setting symbol in symbol field too
Remember due to last character missing prob (i ve mentioned in prob.). but
once it set the symbol field and v try to edit it again event occured causing
call to setPrice () again
so know i ve understand it and i ll solve it thanx

Any one with the idea why last character was missing when i write in symbol field for example if the symbol is "PTC" when i write PTC in symbol field its price lets say 64.25 is set in price field but symbol field shows "PT" instead of "PTC"
