Displaying decimal places using a TextFieldFloat

2010-12-06 Thread Ian Marshall 

I use a TextFieldFloat as shown below. Since this field represents a
currency unit (in this case, pound sterling) I want to have two decimal
places shown always. For example:
  0.00
  5.00
  6.10
  3.28.

What I find when I run my web application is that, after form submission,
the model's Float value is always shown without any trailing zeroes in the
decimals. To use the same examples again, I get:
  0
  5
  6.1
  3.28.

Is there anything simple I can do to get my component to display two decimal
places always?

(Failing this, I intend to work around my problem by changing the
TextFieldFloat to a TextField with a String for its model, and converting
this String to a Float value myself after form submission.)


HTML mark-up

  lt;input type=text wicket:id=flPriceInPounds size=10/gt;


Java code (within a WebPage)

  Form frmForm = new Form(frmForm)
  {
[...]
  };
  frmForm.setModel(new CompoundPropertyModel([...]));
  add(frmForm);

  TextFieldFloat txtMriceInPounds =
   new TextFieldFloat(flPriceInPounds, Float.class);
  frmForm.add(txtPriceInPounds);


Java code: declaration within the form's compound property model

  public Float flPriceInPounds = null;


Regards,

Ian Marshall

you can keep the field as float and give it its own converter that
always shows two decimal places

Hi Ian, you can provide an BigDecimalConverter that works with an
NumberFormat with its minimumFractionDigits setted to 2
