[richfaces-issues] [JBoss JIRA] (RF-10994) DnD: scripts not getting loaded via ajax

[Brian Leathem (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/RF-10994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12642246#comment-12642246 ] 

Brian Leathem commented on RF-10994:
------------------------------------

The reason it works when not _<h:head>_ tag is present, is because the scripts are rendered into the body.  There must be some kind of check preventing the script from being rendered into the head - maybe the logic thinks it's already present?

> Tree by default using ajax mode. So when you expanding nodes  -leafs which getting loaded should be draggable. But there is no draggable script resource so you could see JS errors instead saying that Draggable si not a constructor.
> If change toggleType to client - works fine. If add any draggable component to the page - it also starts works as scripts already inplace.
> (should be easier to reproduce with tab panel or just conditionally rendered panel for example).
