    [ https://issues.jboss.org/browse/RF-12593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12823172#comment-12823172 ] 

Lukáš Fryč commented on RF-12593:
---------------------------------

The issue is that {{toScriptArgs}} suppose to return not only collections, as can be seen in the test:
https://github.com/richfaces/richfaces/blob/master/framework/src/test/java/org/richfaces/renderkit/RenderKitUtilsTest.java#L134

In this case, it would be much better if it return:
* empty hash {{{}}} when empty map provided
* empty array {{[]}} when empty collection or array provided
* {{null}} if null provided

> The {{toScriptArgs(Object object)}} should always return JavaScript object:
> {code:javascript}
> { ... }
> {code}
> In case null object or no not-null parameter provided, empty object should be returned:
> {code:javascript}
> {}
> {code}
> Currently, it returns empty string {{""}} which is not handy if we expect JavaScript object as a return value.
