Use SpryValidationTextField to check Currency Decimals

Question

I have a SpryValidationTextField widget defined in my form to
see whether a currency field has a certain minimum value. It works
fine as lomg as I integer values as minimum values. As soon as I
use decimals the valuation starts going horrorably wrong; the
system will allow any value to pass really, as long as they have
the correct format.
I assume this is a bug of the validation function.
Can an Adobe member of the forum please suggest an
appropriate fix or point out what I am doing wrong.
<span id="sprytextfield1">
<input type="text" name="cost" id="cost" value="0.00"
size="32" />
<span class="textfieldRequiredMsg">A value is
required.</span><span
class="textfieldInvalidFormatMsg">Invalid
format.</span><span class="textfieldMinValueMsg">The
entered value is less than the minimum
required.</span><span class="textfieldMaxValueMsg">The
entered value is greater than the maximum
allowed.</span></span>
<script type="text/javascript">
<!--
var sprytextfield1 = new
Spry.Widget.ValidationTextField("sprytextfield1", "currency",
{validateOn:["blur"], minValue:0.5, maxValue:1000,
useCharacterMasking:true, hint:"Cost in account currency"});
//-->
</script>

Answer 1

This looks like it may be a bug in the
SpryValidationTextField code. You can work around the problem by
quoting your min and max values and if you are going to specify a
digit after the decimal point, make sure there are 2 digits. So in
your example, change:
minValue: 0.5
to
minValue: "0.50"
