rich:tree selected node value on client side

[anonyin]

I have a requirement to capture the last selected node value when the user click on another action(out side the tree) in the page. Is there anyway I could get the last selected tree node value ?

Thanks.

1) You can handle every user selection and save it on server. Like this

2) You can handle every user selection by onselected event and save selected node in JS variable. It could look like this:

onselected="handleSelectionJSFunction(#{treeItem.id});"

Thanks for the reply.

onselected will give me the value when we click on the tree node, yes I could certainly capture it on server side by passing the selected node value to the refresh function below. Infact I'm doing it.

<a4j:jsFunction name="refresh"

                action="#"

                reRender="data">

                <a4j:actionparam name="param1" assignTo="#{bean.treeNodeId}" />

</a4j:jsFunction>

But when I click on another action(Say Search) in the page(this link/button is not part of the tree its outside the tree) I want the value of the last tree node selected before clicking Search button to be passed to my bean. Eventhough I set the value of the treeNodeId in the bean when click on the tree node, by the time I click on the search button that value is lost.

Any otherways to acheive this will also help.

Thanks.

Look at the following link:

I guess you need to pass selectedNodeId in actionparam inside a4j:commandButton - Search button.

P.S. Make sure that you do save selectedNodeId in a JS variable. Use alert command or debug your JS in firebug.
