[GRAILS] using different formats for BigDecimal in bindData

Question

Hi,

i have a class

class Foo {

BigInteger phase
BigDecimal amount
BigDecimal percent

}

and want to use bindData to map some user input.
The user enters data in different formats for amount and percent

i.e. :

• amount : 100.000,00
• percent : 75,50%

bindData parses this to

• amount = 100000 (in GERMAN Locale)
• percent : 75.5

is there any way to force grails to format domain-fields using different formats? For the example i would use NumberFormat.getNumberInstance for amount and NumberFormat.getPercentInstance for percent using the current Locale....

I tried the CustomEditor thing, but this procedure is type-bound and will not work on two different formats using the same type...

Anybody any idea? ;)

Thanks, Alex

Using a CustomEditor should work. You just pass a custom date binder that can determine the value being submitted and transform it. In our app for example, we have a custom date binder that transforms a single date field (normally Grails expects the date split into three fields).
