Limiting the fraction part in float values

[Nikita Shah <ni...@yahoo.com>]

 Hi
  
  I have a jsp where i want to input float values, but i dont want the  user to enter more then 1 fraction digit. Can we set this limit   ..?
  
  I have tried using f:convertNumber in following way
  
  <h:inputText size="3" id="taL7" value="#{targetactual.l7}" >            
         <f:validateDoubleRange minimum="1.0" maximum="7.0" />
         <f:convertNumber maxFractionDigits="1" />
  </h:inputText>
  
  where targetactual.l7 is of type float.
  But i get error on entering float values - "taL7": Error during model data update. 
  Any idea why do I get this error..?
   [input]  [input]  [input]   
  Any help wud be appreciated.
  
  TIA
  ~Nikita

I had the same problem. You need to declare the object in the
backing bean as java.lang.Number not float. You can then
convert it from/to float in the getter and setter.
 
public Number getL7() { ... }
public void setL7(Number l7) { ... }
