[richfaces-issues] [JBoss JIRA] Commented: (RF-3986) oncomplete documentation in richfaces_userguide.pdf wrong

[Alex Tserbo (JIRA)]

    [ https://jira.jboss.org/jira/browse/RF-3986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12436627#action_12436627 ] 

Alex Tserbo commented on RF-3986:
---------------------------------

No, the EL-expression passed with "oncomplete" would be evaluated after an AJAX response. The description is correct, but as it seems to me could be interpreted wrong. This one would be a bit more definite:  "Before AJAX request is sent, the RichFaces registers the code, which is passed with "oncomplete" attribute, for invocation of XMLHTTP request after AJAX response comes back. ". So, not invocation of XMLHTTP happens before AJAX request but RF registers the EL before AJAX-request.

> I assume there is a bug in the current richfaces-userguide.pdf, section 5.4.5. JavaScript Interactions:
> It says:
> "oncomplete" attribute allows to invoke the JavaScript code right after the Ajax Response is returned back and the DOM tree of the browser is updated. Richfaces registers the code for further invocation of XMLHTTP request object before an Ajax request is sent. This means the code will not be changed during processing of the request on the server if you use JSF EL value binding. Also, you cannot use "this'" inside the code, because it will not point the component where Ajax request was initiated.
> Is this description deprecated or is the implementation in richfaces 3.1.5 wrong?
> sample:
> actionListener="#{mybean.al}"
> oncomplete="#{!empty requestScope['someVar']?'doA();':'doB();'}"
> depending on what I do in my actionListener doA or doB is called.
> Therefore I think the documentation has to be updated.
