Hello again.
I was trying settting up a formatter, but I dunno what Im doign wrong..
I have the following:
<wo:WOTextField value = "$price" numberformat = "$doubleFormater"/></
span>
and in the java file:
doubleFormater = new NSNumberFormatter("#,##0.00");
/**
* @return the price
*/
public Number price() {
return price;
}
/**
* @param price the price to set
*/
public void setPrice(Number price) {
this.price = price.doubleValue();
}
but I get then the following excetion:
Jun 10 13:38:56 LocXManager[59322] WARN NSLog -

instead a binding to a string and the parsing the string into the
double... I mean is it possible?

Hello I have some WOTextField which the value is a double, in the
accessors methods should I bind it to a NSNumber?, or use a
numberFormatter.. which in case I dunno how to specify it,... I saw
in the documentation how to specify a NSFormatter with a date but
for the numberFormatter, in my case a double,.. how I specify the
formatter?
If I bind the WOTExtFields to a double only, I get an exception. and
it tells me that this often happens when no formatter has been
specified.
where am I wrong?
Thx
Gustavo
