I ported our codebase to 3.4.1.1. The updated fixes are in the original post. As pointed out by @wm003 most of the fixes are still needed. Not that much changed between 3.4.0 and 3.4.1.1, so...

I updated the first post with the most recent version of the overrides for 3.4.0. There's a bunch of new ones which I hadn't posted here yet.

The one to be especially mindful of is the htmlEncode...

I will be upgrading our codebase to 3.4.1.1 this month most likely (it's a bit of a challenge because there are 100.000 lines of code in that codebase). At that point I'll go through the fixes file,...

Is anyone actually running complex applications (> 50.000 lines) on IE7 / IE8 with ExtJS 4.x?

My base requirements are acceptable performance on IE7 and good performance on IE8, and I'm wondering...

I've used just about everything else, only to realize I could have saved myself a lot of trouble jumping directly into the jetbrains bandwagon.

[by joeri]

As someone also stuck with a big codebase on 3.4, I'd like to add that I do think the ExtJS 4.x transition was necessary. Could it have been managed more smoothly? Yes. But it was in my opinion...

Wow, wow, please don't put words in my mouth.

I do not deny that adding modules and classical OO syntax at the language level would provide many benefits. If you look back in the thread I pointed...

That is an assumption for which I do not see much evidence. AS3 is javascript + static typing, and it is outperformed by V8 and Tracemonkey. Modern JIT engines observe code at run-time to infer types...

I guess we'll just have to agree to disagree on the impact of TypeScript on code quality. I doubt that many bugs in ExtJS would be avoided if it was developed in TypeScript, based on my experience...

I think if your team is struggling with the things in JavaScript that make scaling more difficult, TypeScript will not save them. It will just remove one issue from a list of dozens of issues that...

I had a hostility to the claim that JavaScript is unsuitable for large-scale development, not to TypeScript.

Now, if you ask my opinion about TypeScript itself, I see it as an experiment of where...

[by joeri]

I think everyone agrees that having support for TypeScript in combination with ExtJS would be a good thing.

The argument is about whether a static typing solution like TypeScript is essential for...

Except the big issues are all related to thrashing the DOM, and TypeScript does not solve that in any way. The DOM is simply not an API you want to write large systems directly on top of. That's why...

Well, now that you point out these words from Anders Hejlsberg, I've suddenly realized that for many years I was completely deluding myself that we were being productive in JavaScript. Many thanks...

Ahem, our product has 90.000 lines of ExtJS and Sencha Touch code (excluding whitespace and comments), and we don't think JS sucks. In fact, I personally consider it my favorite language.

If it's so easy to style ExtJS with SASS, where are all the amazing SASS-based sencha themes?

@wm003: Actually, i've taken a look at SAP's HTML5 UI toolkit, and it's indeed not as bad as you would think. It's very un-SAP-like.

It is purely client-side, and integrates with the server via...

So, ExtJS is built on sand? ;)

One more reason to be concerned about global warming and rising sea levels.

[by joeri]

In my opinion ExtJS needs to become more touch-friendly.

I think merging Sencha Touch and ExtJS is not practical at this point in time. Merging the layout systems is prohibitively complicated (and...

In case anyone is considering webstorm, jetbrains are doing a 75% off sale today (and their servers seem to be melting under the load).

Detached DOM elements being kept in memory are a typical symptom of leaking memory by having a circular reference from the DOM element to a javascript object and back to the DOM again.

The way to...

[by joeri]

Like in any garbage-collected environment you get memory "leaks" when unused data is kept referenced in memory "somewhere". ExtJS and ST apps are sensitive to this because they have many layers of...

Ugh, that's exactly the wrong response. Be clear and be public.

I'm not going to contact sales. It's your job to have a transparent pricing structure, not mine.

Since my comment on the blog post seems to be stuck in moderation (given a more recent comment was let through), I'm going to ask again here.

Will sencha provide a mechanism for existing customers...

It would be interesting to know the exact technical roadblocks to supporting windows phone 7.5. From my POV supporting it seems feasible, but I admittedly have not researched in detail.
