iOS Question xCustomListView B4i issue

cooperlegend · Feb 22, 2019

No code changed since last week, but now one of my forms is crashing when loading using the xCustomListView library with view "type = CustomView, CustomType = CustomListView" within my form.

Has something changed ?

If I remove this view from the form, it loads fine (just doesn't show the view of course)

Can you post the full error message?

cooperlegend · Feb 24, 2019

I am struggling with that one. I have been unable to run my code in debug for quite a while now (it wont load)
This bug just crashes out of the program.

If only I can suss out why debug no longer works.....

You need to provide more information. What happens when you try to run it in debug mode? Does it happen with this project only or with all projects.

cooperlegend · Feb 24, 2019

OK, I somehow got debug to run and go this log code.

This problem is affecting all my other projects which use the customlistview, as soon as I re-compile the projects and run the they no longer work.
So I am guessing something on the Hosted Builder is broken causing this... ????

Erel · Feb 24, 2019

I'm unable to reproduce it. Can you upload a small project that shows this error?

Make sure to reference xCustomListView library. Don't add CustomListView code module.

cooperlegend · Feb 25, 2019

Thank you, small project attached

Erel · Feb 25, 2019

I've ran your project, compiled with the hosted builder. I see a black screen with "start" button. I click on it and it switches to an empty page.

cooperlegend · Feb 25, 2019

Oh, when I run this it crashes instead of showing the second (courses) page, I am compiling with your hosted server.

Both this and another project do the same when trying to load the customlistview pages.

No code has changed on either of these projects (in that area)

And this does this on both PCs that I have licenses for.

Something changed in the last week ,,,, I am stumped...

Try to uninstall the existing app, clean the project (Ctrl + P) and run again.

cooperlegend · Feb 25, 2019

Still no joy

I even started a brand new project and just created two pages, button on page 1 calls page 2 with the customlistview and this still crashes.

cooperlegend · Feb 25, 2019

Also tried just one page with just the customlistview on it
re-downloaded both the certificate and mobileprovision

tried both build hosts.

No issues here. Using B4i version 5.50 and online build server. I do not use #CertificateFile or #ProvisionFile.

Erel · Feb 26, 2019

Try to reinstall B4i in a new folder.

cooperlegend · Feb 26, 2019

OK, further info.

This bug is only happening on my older devices, iPad Mini on OS 9.3.5 and iPod Touch. Latest iPad Pro on 12.1.4 works fine. Any ideas?

Erel · Feb 26, 2019

Have you uninstalled the existing app from the iPad Mini?

What happens in release mode?

cooperlegend · Feb 26, 2019

Hi, The "Test" project was a new install anyway, but I tried again just now and re-installed both B4i-Bridge and the Test project and it does not work on either my iPod Touch or iPad mini both running 9.3.5 but works fine on my other later OS devices.
Can someone else try this on their older device(s) please.
I also re-installed B4i 5.51
These were in release mode.

cooperlegend · Feb 26, 2019

p.s. Why does my release say 5.51 when 5.50 is supposed to be the latest ?!?!? I re-installed from the last emailed link you sent me (Is this the cause of the issue?)
