Howard M. Lewis Ship commented on TAP5-2429:
--------------------------------------------
It seems like the heart of the problem is that you have one representation for
the data on the client side and another on the server.
I still could use more details about what Tapestry is doing, not doing, or
doing incorrectly here. Do you have @Validate on the numeric field in question?
Can you address this by adding a custom @DataType for such fields?

> Key: TAP5-2429
> URL: https://issues.apache.org/jira/browse/TAP5-2429
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.3, 5.4
> Reporter: Geoff Callender
>
> Tapestry has client-side translators which, on input, translate before
> validation. They use the same error-reporting mechanism as the validators
> (highlight the field and its label, display the message below the field).
> However, we cannot contribute our own translators. Consider these situations
> where the server-side field is numeric:
> Enter amount: [ ] (eg. 2k=2000, 5m=5000000]
> Enter elapsed: [ 2:30] (min:sec)
> Enter duration: [ 2m30s] (eg. 1m17s)
> When the server-side is numeric and the client-side representation is
> non-numeric, it fails client-side validation because it's not a number. If we
> could do client-side translation then this would be solved.
> Currently, instead, we have to disable client-side validation. For a live
> example, see the 4th field here (Preview 25):
>
> http://jumpstart.doublenegative.com.au/jumpstart7/examples/input/augmentingtranslators
> I've seen a suggestion that Translator#render(Field field, String message,
> MarkupWriter writer, FormSupport formSupport) might solve this. If so, then
> perhaps this should be a documentation request because I've been unable to
> find any examples in the documentation.
