Ext 3 to 4 Migration

[brookd]

I know this is answered somewhere before, sorry, could not find it. My Question is how long will 3.4.0 be supported and maintained?

I'm stuck on it for a while..

Rather unlikely at this point - not sure what it would contain

How about fixes for future browser support?

Just started migrating my Framework in Ext 3.0.4 to 4.0.6.

I figured out some issues with comp. layer May 27!
I will post the issues to not forget something:

1) Window

Window (Line 945) need something like
if (!config) config = {};
because constructing windows without default config are not handled correct and throws errors!

2) annonying info LoadingText in the Framework itself!
Please fix for 4.0.7!
I think the message
[DEPRECATED][4.0][Ext.form.field.ComboBox] loadingText (config): Use listConfig.loadingText instead.
comes from the framework internally (see ext locale de file) 197+
if(Ext.form.field.ComboBox){
Ext.apply(Ext.form.field.ComboBox.prototype, {
loadingText : "Lade Daten ...",
valueNotFoundText : undefined
});
}

3) Info implicit model
[INFO][4.0][Ext.data.Store]: Registering implicit model Ext.data.Store.ImplicitModel-ext-gen1072. Please update your code to create a model explicitly.
Why this? implicit models are allowed (ex. Grid->Fields) ans are a great shortcut.
Maybe config option to disable annonying info (will disable it in coding line 1423!) because i will continue use implicit models in some cases and it is blowing my debugging output during migration!

Hi Guys,

I started thread in Q&A ext4.0 I am facing problem of timefield when I remove extjs3.0-compat.js file from project.

Can we get an answer to this question and mine? How long will 3.4 or "pre 4.0" code base be supported?? I wish I could upgrade, but as you know 4.0, its not exactly backwards compatible. Something thats already cost me tens of thousands of dollars. Thanks for that!

How about fixes for future browser support?

We will have a nice solution for this soon.
Stay tuned

[brookd]

A nice solution for what exactly? The fact that its gonna cost be tens of thousands of dollars in development hours to move to 4.0? Support for 3.4.0? What exactly?

[Ekambos]

No man. For that i cant really help. Sorry you have to spend that much money.
We are working on a solution that will make migrating from Ext3 to Ext4 and vice versa more easier. That s what i ment.

So how long we can keep this below code in our index and js file.

<script type="text/javascript" src="lib/compatibility/ext3-core-compat.js"></script>
<script type="text/javascript" src="lib/compatibility/ext3-compat.js"></script>
Ext.Compat.showErrors = true;

See , I know Timefield is date type now. so I need to explicitly render the Time field. But I dont think this is a solution for all. It should work similar way as string type.
Please suggest us, as we have migrated our code to Ext4.0 but dont know how long we need to keep that supporting/compatibility code in the files.

Version May 27 throws store implicit model exception when adding Array Store inside ComboBox field,
but this is an allowed option! see API docs for Ext.from.field.ComboBox configOption: store

• any Store subclass
• an Array : Arrays will be converted to a Ext.data.Store internally, automatically generating field names to work with all data components.
  

Using this will avoid annoying notification message that is wrong is such a case!

var id = 'Ext.data.Store.ImplicitModel-' + (config.storeId || config.id || Ext.id());
if (!config.store instanceof Array) {
notify({pkg:'Ext.data.Store', msg:'Registering implicit model ' + id + '. Please update your code to create a
