[jira] [Commented] (WICKET-6370) Add default converter for Optional

["Martin Grigorov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-6370?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16006553#comment-16006553 ] 

Martin Grigorov commented on WICKET-6370:
-----------------------------------------

Do you have an idea how to implement it ?
Because as I said in WICKET-6200 due to the type erasure it is hard (impossible ?!) to get the type of the value inside of Optional.
The problem is: 
1) the browser sends String
2) Wicket sees that the type is java.util.Optional
3) how to find what is the type of the object inside Optional? Is it a String, or an Integer, or Date, or anything else ?!

> It would be great to have default converter for Optional. Using Optional in PropertyModel and CompoundPropertyModel would be much cleaner than null checks later in application.
