I am very glad to hear that.
In my project, I create three views for one entity, such as SimpleComment, DetailComment, FullComment.
I need to cry now..

Hi Leo,

Thanks for the samples i can run it successfully, i will check the three issues (scroll, image loader, and incremental) using this samples now.

Please note i use Crosslight v4 to test this issues (to check whether it already fixed in v4), also you can expect cool new features in v4 by the way! (like view projection, which only obtain needed data make your list become so much faster)

Hi Leo,

Looks like i encounter error when running your new samples (Index was out of range), can I use your old samples which still functional? (obtained in the top)

Did i'm still must swipe fast to reproduce the issue?

Hi Arief,

I updated my client assembly to Crosslight 3.0.5000.231
Duplicated sending issue is reproduced when incremental loads data.

Please take a look at my attachment & image:

My internet connection is also fast, about 20Mb/s, my server bandwidth is 1Mb/s.

I think this issue happens when the first response data is loaded but the UI is still calculating, and then the second request sends out immediately, when the second response data is also loaded into memory, the UI tries to reload UITableView and cannot decide current scroll position.

Just my imagination.

This issue should happen when swipe the UI so fast, or the layout of the UITableViewCell is too complicated to perform WillDisplay and GetHeight.

When uses dynamic height supported UITableViewCell, I found that the incremental loading behavior is strange.

On iOS 8.0 or higher platform:

The UITableViewController will incremental load data several times, it may have 3 or more http requests sent out at same time (page index range may be 10-20, 20-30, 30-40). After data loaded, the table will refresh and scroll bar may move to top (sometimes then move back to current postion).

On iOS 7.0 platform:

When scrolls the content to the bottom and incremental loading begins, an Unhandled exception will be thrown, and the app will exit.

This issue only happens when uses UITableViewCell that implements ISupportDynamicHeight and UITableViewController set to TableViewCellStyle.Custom. Please take a look.
