TabbedPageWorkarounds: blank page after adding a tab

[tranb3r]

I've reported a few days ago here that I experienced an exception when programmatically adding a tab to a TabbedPage.

The exception has been fixed in version 1.2.4 of the TabbedPageWorkarounds.
However, when adding a tab, the current tab now becomes blank.

Could you please take a look? Do you need a repro?
Thanks!

@tranb3r yea can you add a repro?

Hopefully I can make this one work :-/

I did a PR over on MAUI that once we back port will make this all easier but, in the mean time 🤞

I've updated my repro here: https://github.com/tranb3r/Issues/tree/main/MauiAppTabbedPageBlank

Just launch the app and click on 'add tab' button. It's supposed to add a new tab to the tabbedpage.

• with 1.2.3: there was an exception
• with 1.2.4: the exception has been fixed, but the current tab becomes blank

@tranb3r alright pushed up another hack on the stack :-)

It'll flicker a little bit but I don't think I can fix that currently. I have some updates percolating inside MAUI that we'll hopefully backport to NET7 and then I can just remove all these hacks and the original code should work fine.

I've tested 1.2.6.
'add tab' does work. However, navigation is broken.
To reproduce, open the same sample, click on 'add tab' and then 'push page'.

Could you please take a look?
Thanks!

yea this is a tricky one :-/ I'll see if I can find a workaround, worst case we have a PR that will make it out to an upcoming 7.0 SR that should fix the cast exception

[tranb3r]

I've just tested the new maui SR (7.0.81).
The blank page issue is still here.
Could you please help and provide a fix?

Try the latest pushed version

I still had the workaround in place that didn't really work.

I've tried all versions of your nuget.
The TabbedPage is always broken.
Either it crashes, or I get a blank page, or the navigation does not work.

[tranb3r]

Version 1.3.1 has just appeared in my nuget feed.
I've tested it and it seems all issues are now gone.
Thanks a lot!
