Andrew Robinson commented on TRINIDAD-1055:
-------------------------------------------
Assigning this to me to have a look as I added the hide root node
functionality.
> Navigation from treeTable fails if rootNodeRendered="false"
> -----------------------------------------------------------
>
> Key: TRINIDAD-1055
> URL: https://issues.apache.org/jira/browse/TRINIDAD-1055
> Project: MyFaces Trinidad
> Issue Type: Bug
> Affects Versions: 1.0.7-core
> Environment: Observed with Windows XP, IE6 or Firefox 2.0.0.14,
> Apache MyFaces Core 1.1.5 and Trinidad 1.0.7.
> Reporter: Dirk Krummacker
> Assignee: Andrew Robinson
>
> I have a simple JSP page with only a commandButton and a treeTable. The
> commandButton is wired to an action listener method that populates a list
> with nodes and places it into page flow scope. This node list serves as the
> treeTable's model. There is a column in the treeTable displaying a
> commandLink, clicking on this link causes an action that is navigating to a
> second page. The backing bean is in request scope.
> When I use the default rootNodeRendered="true", this page works as expected:
> First the treeTable is empty. Clicking the button fills it, and now I can
> open and close all nodes. If I click on a commandLink in the treeTable, I am
> taken to the correct page. Everything is fine.
> However if I now set the treeTable's attribute rootNodeRendered="false" (and
> change nothing otherwise), the commandLink navigation stops working. I still
> can open/close nodes, but any click on a commandLink just causes the page to
> refresh.
> What is more, if I now click on "Expand all", the commandLinks suddenly start
> working again, just as if this "Expand All" click
> "repaired" the treetable. Also, if I specify initiallyExpanded="true" in the
> JSP it works even if the root node is hidden.
> There is no change in behavior if the action method is specified on the bean
> instead of the row object.
