Render to new dynamic tab (using rails)

[ebaker280]

I'm using Ext with Ruby on Rails. I have a viewport with a border layout. In the west region is a site navigation tree, and in the center region is a tab panel. My navigation tree listener responds by creating a new tab in the tab panel and loading a url:

listeners: {
                  click: function(n) {
                      var t = tabPanel.findById(n.attributes.text);
                      if (!t) {
                          t = tabPanel.add(new Ext.Panel({
                              id: tabId,
                              title: "Tab titles goes here",
                              closable: true
                          }));
                      }
                      tabPanel.setActiveTab(t);
                      var updater = t.getUpdater();
                      updater.update({
                          url: "/ror_controller/" + ror_action,
                          scripts: true
                      })
                  }
              }

The javascript in my RoR action template is eval'd, but how do I render an Ext component into my new tab? In other words, if I embed javascript code within my RoR view template that creates Ext components, how do I make those components render to the new tab? For example, how do I display a new panel, or a grid panel, within the newly created tab?

Thanks!

I'm such a noob! All I needed was the id of my new panel, and then I can call add() with new components. Doh! I think Ext is finally starting to "click" for me.

If you insist on adding a new Component inside a Panel which is added to a TabPanel, then at least consider the layout of that completely redundant wrapping Panel.
