Subject [jira] Commented: (WW-3385) (Application|Session|Request)Map.put(key,value) breaks Map-contract, returning new value, not old value
Date Wed, 17 Feb 2010 16:43:27 GMT

    [ https://issues.apache.org/jira/browse/WW-3385?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12834831#action_12834831

Lukasz Lenart commented on WW-3385:
-----------------------------------

You mean

V oldValue = get(key);
request.setAttribute(value);
return oldValue;

?

>             Project: Struts 2
>          Issue Type: Improvement
>          Components: Dispatch Filter
>    Affects Versions: 2.1.8.1

>            Priority: Trivial

> Noticed that the Map-wrapper classes (org.apache.struts2.dispatcher.RequestMap etc.)
returns the new value from put-method.
> request.setAttribute(key.toString(), value);
> return get(key);
> Should be:
> V value = get(key);
> request.setAttribute(key.toString(), value);
> return value;
> in order to be consistent with other Map-implementations.
