Scrollview broken in new daily build 2015.2581

corona273 · March 13, 2015, 3:58am

I’m encouraged to see that the latest daily build (2015.2581) has no fewer than 26 changes to the widgets, mostly scrollview, tableview, and pickerwheel. It’s great to see Corona addressing some problems with this library.

I’m sorry to report, though, that the changes have broken the scrollview widget: scrolling is no longer possible.

You can verify this with Corona’s sample Interface/ScrollView code. Scrolling works on 2015.2574. It doesn’t on 2015.2581 (the content springs back into place after an attempt to scroll). This behavior is present on the simulator and device.

In addition, if you set isBounceEnabled = true, the content doesn’t move at all.

I’m delighted to see the widgets get some love, and I hope that this will be an easy fix.

There’s an additional problem with the latest daily build, though it’s harder to describe:

Take the sample Interface/ScrollView code. Touch the scrollview and drag your finger off the screen to the top or the bottom. Repeat until the all the content in the scrollview is offscreen. It should not be possible to empty a scrollview this way.

I am experiencing the same issue

I’ve reported this to engineering.

Thanks, Rob.

It seems that if you setScrollWith after inserting objects it works. Can be useful if you have to use 2581 in order to use other improvements

Yeah it’s bust alright, basically if you scroll without your finger going outside the scroll area it’s fine, if you you scroll in any direction and you lift you finger up outside the scroll area the scroll does not bounce back, it stays where it is.

Engineering is working on a fix.

Has this been fixed in the recent daily releases?

corona273 · March 20, 2015, 4:24pm

It doesn’t look like the daily builds in the last eight days have fixed the bug. There’s no mention of any changes to any widgets since March 12:

Hi @corona273,

Have you tried the most recent build, i.e. 2589? I’m almost sure this fix went into QA yesterday or the day before, and it should be rolled into a daily build very soon, if it’s not already (but sometimes this doesn’t happen immediately after a fix clears testing).

Brent:

Thanks for your response – you folks have been busy! Lots of daily builds. But I just tested 2589 and it’s not fixed yet.

bjsorrentino · March 20, 2015, 10:34pm

OK, it should be soon… let me bump the engineers on pushing out this fix.

It’s still broken in 2590.

bjsorrentino · March 23, 2015, 9:56pm

Hi guys,

I believe this fix will be integrated in the next daily build, i.e. #2591 or #2592 at the latest.

Thanks,

Brent

Brent: Thanks for your help. Alas, scrollview and tableview in the latest daily build are still broken. Until you fix it, apps that use the standard pull-to-refresh gesture will not work.

(I think they are broken in a new and different way than they were previously, if that helps. My guess is that your March 24 changes in 2015.2594 introduced the new bug.)

You can test this for yourself by using your Scrollview sample project.

In daily build 2015.2574, prior to your widget changes, pulling to refresh and then dragging your finger off the screen to the bottom generated these console results:

2015-03-26 23:34:22.885 Corona Simulator[35823:507] Moved 2015-03-26 23:34:22.933 Corona Simulator[35823:507] Ended 2015-03-26 23:34:22.965 Corona Simulator[35823:507] Reached Bottom Limit

In daily build 2015.2598, the identical sample project, with the identical gesture, generates these:

2015-03-26 23:35:38.425 Corona Simulator[35877:507] Moved 2015-03-26 23:35:38.444 Corona Simulator[35877:507] Moved 2015-03-26 23:35:38.460 Corona Simulator[35877:507] Moved

I’m surprised you didn’t test your own sample projects against the new build!

Can you let us know when this widgets will be fixed? And just to be clear, this affects tableview as well.

corona273 · March 30, 2015, 11:12pm

I still haven’t heard back from anyone at Corona about an estimated fix date – scrollview has been broken for nearly three weeks of daily builds, and tableview for a week – but for those folks following the discussion here, the bug report # is in this thread:

Hi @corona273,

This fix has cleared testing and should roll into a daily build shortly upcoming.

Thanks,

Brent

corona273 · April 5, 2015, 6:21am

Thanks, Brent. I downloaded 2015.2605 and (albeit only a brief time testing) both tableview and scrollview seem to be fixed.
