Hi all,

I've got a text field that I have bound to a Number object. When I enter a numeric value
into the field I get the following message...


While trying to set the field "age" on an object of type Main we expected a java.lang.Number but received a java.lang.String with a value of 45. This often happens if you forget to use a formatter.


I'm not quite sure how to use a formatter. I put in "###" and "##0" directly into the formatter field
for the text field, as well as creating a key numberFormatter of type NSNumberFormatter, binding
it to the formatter attribute of the text field, and setting it via...


	        numberFormatter.setFormat("##0");

in the constructor for the component.
Clearly all of these are wrong, so I'm not sure where to go now.

Either you set the formatter pattern or a formatter object. Most of the times binding the numberFormat is enough unless you have some special needs, say custom thousand delimiter or things like that.
