[jira] [Commented] (TAP5-1948) NullFieldStrategy interface should have a reference to client\server provided value

["Howard M. Lewis Ship (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-1948?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13472445#comment-13472445 ] 

Howard M. Lewis Ship commented on TAP5-1948:
--------------------------------------------

It is very disruptive to change an interface after it has been out for a long time, especially in terms of changing the parameters to a method described by the interface.

On the other hand, the Translator interface appears to do what you need ... it gets the actual server-side value and the actual client-provided string.

>             Project: Tapestry 5
>          Issue Type: Improvement
>          Components: tapestry-core
>    Affects Versions: 5.3.3, 5.3.4, 5.4
>            Reporter: Muhammad Gelbana
>              Labels: NullFieldStrategy, blank, input

> And it affects all previous versions. My case is that I should accept blank inputs from the client through text fields. By blank inputs I mean "nothing" and one or more spaces.
> Now the NullFieldStrategy interface doesn't provide a clue about the value considered by tapestry to be blank. Like in my case, I actually need to know if the user provided a space or more or even nothing at all ? I just need the value as it is.
> Thank you.
