View Full Version : How can I process ExtJS 4.2.1 tree item text before it is rendered?

I need to swap the localization IDs with their actual string values (for the current locale) in tree data.

So if there were an event such as renderTreeItem, in its handler I might do this, where StringMessage.getResource(id) returns the localized string for the id:

onRenderTreeItem(text) {
return StringMessage.getResource(text)

root: {
expanded: true,
children: [
{ text: "detention", leaf: true },
{ text: "homework", expanded: true, children: [
{ text: "book report", leaf: true },
{ text: "algebra", leaf: true}
] },
{ text: "buy lottery tickets", leaf: true }

I use a convert function in the tree model.
