You might also try something like the jenia components. I use their
multipleSelector component with a datatable. However, I imagine it
could work with a tree.

Hi,
I'm sory for this question, but there's not too much doc about this on
site, so... here we go:
I want to make a tree2 with checkboxes that I only collect once
together, and I could use some advice:
The examples I've seen, have the commandlink at every node, by
consequence fire off the second one gets clicked.
What I want, is:
- a CLIENT side tree2 (for speed)
- with checkboxes on every leaf element
- multiple leafs can be checked simultaneously ("simultaneously"
meaning before a new request fires off)
- under the tree a cmd button to ONLY THEN fire off an action.
The action should then perform an opeation on all the checked leafs.
I guess thsi is possible, but how to do this best?
If possible, I'd like a solution without javascript to collect the
checked nodes, yet if no other way exits, that's fine too.
With js I thought of smth like: (if it works,
"addToRequest(#{node.identifier});" ... should add the node ID to the
request. So all checked nodes would be sent with the request wen the
cmd button under the tree gets clicked.)
<t:tree2 id="clientTree" value="#{calmgmtbean.treeModel}" var="node"
varNodeToggler="t">
<f:facet name="setsTree">
<h:panelGroup>
<h:selectBooleanCheckbox
onclick="addToRequest(#{node.identifier});" />
<t:graphicImage value="..pics/calMgmt/document.png"
border="0"/>
<h:outputText value="#{node.description}"
styleClass="#{t.nodeSelected ? 'treeSetSelected':'treeSetUnselected'}"/>
</h:panelGroup>
</f:facet>
</t:tree2>
If possible, I would like to get rid of
"addToRequest(#{node.identifier});", of even better of the entire
"h:selectBooleanCheckbox" and use checkedNode (smth Matthias
Wessendorf provided us with for convenience - thank you Matthias! :-)
Yet in that case, how to collect all the ckecked nodes at the server
side?
Is it necessary to walk over all the nodes and perform a isChecked
check? (if so, does someone here has some tested code for this? Would
be a ice addition to http://wiki.apache.org/myfaces/Tree2 as well.
I think this would also be a fine candidate for a build-in method, to
ship with the ckeckNode tree. As with a checkednode tree, you have the
great option to batch process all checked nodes at once, serverside,
compared to all the servertrips per checked node you'd have without a
checkednode tree. (this is what I love most about it, it's a great
idea, yet now I guess every dev has to program the same method over
and over again for tree-traversal)
Thanks in advance,
Phil
