[richfaces-issues] [JBoss JIRA] (RF-12696) Tree: loading facet doesn't work for first click

[Brian Leathem (JIRA)]

    [ https://issues.jboss.org/browse/RF-12696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12743948#comment-12743948 ] 

Brian Leathem commented on RF-12696:
------------------------------------

The "loading.gif" is not fetched from the server until after the first ajax expansion takes place.  To correct this issue, we would have to aggressively render the loading facet.

A possible workaround is to directly include the image resource elsewhere on the page so that it is aggressively loaded (with _display:none_ for instance)

> # deploy Metamer and open http://localhost:8080/metamer/faces/components/richTree/simpleSwingTreeNode.xhtml?templates=a4jRepeat
> # check "Test Loading Facet" and "Delayed Render (1sec)"
> # toggle some node in first tree, e.g. "Europe"
> # toggle the same node two more times
> result:
> * tree node's icon should change to a loading icon
> * loading facet works for second and all following requests
> * there is the same problem when tree is inside all iteration components - a4j:repeat, rich:dataTable, rich:cst, rich:edt, rich:dataGrid, ui:repeat
