Hi! I have a problem reagarding listview function after
I was using a three listview, and if I select one item in first listview, the selected items will be showed at second list view.
And then if it is one item selection in second listview, the selected items will be showed at thired list view.
If I reslected a items again at first or second listview, new contents view be showed at second list or thrid list

But, from new relase '23th, Aug., it is wrong working.
For example, when I try to slected a item in first or second listview after first selection, it always selected item in last seletion.

Can you post a copy of your project here so that we can test it?

The .AfterPicking events of ListView 1 and 2 are never triggered.

Works like this

gets a bit upset if you do not clear down after listview 3 selection and try selecting an item from listview1 again

Who should that help?
Of course, it should work as I intended in my test app.

anyone who wants to use dependent listviews....

Yes, maybe, but then that's unrelated to the topic here.

You should re-read the OP

Thanks @Anke. That's very strange behavior indeed. I'll see what we can about a fix.

English is admittedly not my native language, but I can't read anything that relates to your answer.

Same observations here.

Making a selection in one lv (listview) causes an additional selection in another lv, and sometimes crashes my app depending on what actions are triggered by the selection.

I like the more compact lv appearances though...

I've added a small app to the gallery to display this behavior.

The app is named ListviewTest210825.

Here's a direct link to the app.

Enjoy...

Is there a way to revert back to a legacy version of ai2 in order to compile broken apps to a usable state?

Actually, I am starting to study other block language for my project!!
I don't know when this problem will be fixed, so I recomend that let you move other block language.

Use the http://code.appinventor.mit.edu.ezproxy.canberra.edu.au server

No complicated projects are needed to show this error. Blocks are also not required. Just add two ListView components to a screen with several items. For example, by clicking on the second item in the first list, the second item from the second list is also highlighted. It seems that only one ClicListener is created for all lists.

test_listview.aia (1.2 KB)

http://code.appinventor.mit.edu.ezproxy.canberra.edu.au exhibits the same corrupt behavior...

:pensive:Does anyone have a workaround for this problem?

Of course, test in compiled apk, or in older version companion v2.60.
