We are building an app with one thousand items in the list. On android the standard Sencha list view is unusable, it is so slow. Buffered list in sencha one was fantastic.

We are desperate to see buffered list working in Sencha 2. If there is any thing that we can do to help get Buffered list working in sencha 2, let us know soon.

Thanks

This sounds great... looking like it'll be a while for Sencha Touch 2, though? If possible, could someone send me the current version of the code for ST2? I could try to help.

THanks

By popular request, attached is the code, with samples, that was mostly working with ST2 PR3. After PR3, there were significant changes to both the Store and DataView classes, which will require this code to be quite significantly reworked.

I am buried in a new job, and unfortunately have almost little time to help on the port.

Good luck.

anyone interested to build this component collaboratively on Git Hub?

I think that the new infinite grid implementation in ExtJS 4.1 is a likely starting point. Just a suggestion.

just wondering, how do you add this component to sencha touch 2? do i need to tweak the sencha js file?

It is used in real project by many users. I have made some fixes and improvements. My list has got 3-4 em items in height so I have made some improvements for it.

I took a shot at making this work on ST2. At least it's showing a list and I can see it rendering on demand, but there's still lots of bugs to iron out.

Here it is: https://github.com/robertklep/buffer...sencha-touch-2

FWIW: I'm not an experienced Sencha Touch programmer, only been working with it for a week or so. More experienced programmers are very welcome

Sencha either needs to get their own version of this out the door, or at least sit a programmer down with this one and updated it for 2.0.1. This is such a crucial feature. Without it, the world of useful ST2 apps is quite unreasonably constrained.

I wish Sencha could at least post something on the subject.
