  1. This does work in Sencha Touch 2. When a field that a convert() function depends on is updated, the convert() function is called.

    I found a workaround based on this blog post:

  2. I have the following model:

    (function() {

    var fourDecimals = function(value, record) {
    return parseFloat(value.toFixed(4));

    Ext.define('App.model.Stock', {
  3. I would like to create a scatter chart and use crosshairs, like this:

    Is it possible to move the y axis over to the right?
  4. Actually, I don't think this completely solved the problem. Now I get

    Uncaught TypeError: Cannot call method 'apply' of undefined

    because of the added call, this.callParent(arguments).

  5. Apparently this.callParent(arguments) needs to be called inside (at the end of) launch(). This solved my problem. Now both launch() and initComponent() are only called once, each.
  6. For some reason, my Ext.application launch() method is being called twice. Additionally, some controls (such as windows constrained inside a panel to emulate an MDI) are being rendered twice.

  7. When I update a store associated with a Sencha Touch list (Ext.dataview.List), the list UI automatically updates (as in MVVM).

    I was trying to reuse a model across ExtJS and Sencha Touch applications. Sencha Touch expects "fields" to be defined inside "config," whereas ExtJS does not.


  10. When I attempt to find a record in an ArrayStore using Sencha Touch 2, no records are returned.

    store.findExact('Symbol', 'GOOG')

    returns -1.

    Okay, so they would be panels with docked, restyled titlebars.

    Is there a way to create panels with title in a Sencha Touch application, like those pictured below?

    I've seen a tear-away tab plugin for ExtJS 3 where you can re-dock tabs to other tab panels or undock them into their own windows. It wasn't perfect, but it was pretty darn good.

    Does any sort of dockable layout functionality exist in ExtJS? Something like described here. Even something third-party or in plugin form is fine.
