Hi again,
Anyone has a clue about obtaining a user's selection in an s:tree element? I
used the example from the showcase, and I don't fully understand the following
script:
<script>
function treeNodeSelected(nodeId) {
dojo.io.bind({
url: "<s:url value='dynamicTreeSelectAction.action'
/>?nodeId="+nodeId,
load: function(type, data, evt) {
var displayDiv = dojo.byId("displayId");
displayDiv.innerHTML = data;
},
mimeType: "text/html"
});
};
dojo.event.topic.subscribe("treeSelected", this, "treeNodeSelected");
</script>
I put in logging inside every method of my dynamicTreeSelectAction action, but
nothing gets logged, so I gather that the node selection is not properly
handled. Can someone explain to me what is going on in this script and why my
action is never being called.
If you need to see the s:tree declaration, here it is:
<td width="90%" valign="top">
<div style="margin-right: 50px;">
<s:tree
theme="ajax"
rootNode="%{treeRootNode}"
childCollectionProperty="childrenNodes"
nodeIdProperty="id"
nodeTitleProperty="name"
treeSelectedTopic="treeSelected">
</s:tree>
</div>
<div id="displayId"></div>
</td>
There used to be some instruction text between the <div id="displayId"></div>
tag, but I removed it. There's a reference to this div in the script above,
but I don't know how it's being used.
Any help would be truly appreciated.
Best,
Session
