Subject [jira] [Commented] (WW-4418) Plugin script resources don't load when action extension is blank
Date Thu, 13 Nov 2014 08:10:33 GMT

    [ https://issues.apache.org/jira/browse/WW-4418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14209469#comment-14209469

Lukasz Lenart commented on WW-4418:
-----------------------------------

Just for reference, it's a bug/feature in {{DefaultActionMapper}}

{code:java}
    @Inject(StrutsConstants.STRUTS_ACTION_EXTENSION)
    public void setExtensions(String extensions) {
        if (extensions != null && !"".equals(extensions)) {
            List<String> list = new ArrayList<String>();
            String[] tokens = extensions.split(",");
            Collections.addAll(list, tokens);
            if (extensions.endsWith(",")) {
                list.add("");
            }
            this.extensions = Collections.unmodifiableList(list);
        } else {
            this.extensions = null;
        }
    }
{code}

>             Project: Struts 2
>          Issue Type: Bug
>          Components: Core Actions
>    Affects Versions: 2.1.8
>            Reporter: Paul Benedict
>            Priority: Minor
>             Fix For: 2.5

> Using <s:head> outputs a link to utils.js:
> {code}
> <script src="/mycontext/struts/utils.js"...></script>
> {code}
> But the file can't be found. FYI, I have no action extension. The solution is to make
the action extension a comma:

> But this is obviously a bug.
