Hi,

I just updated from 2.13.2 to 2.14 and now all my builds give out an empty App. One can see the top Bar (without) any text and the bottom navigation bar, but all content is missing. I migrated to the new build mechanisms too:

build-BerlinVegan-V_Play_Desktop_Qt_5_9_2_clang-Release/
build-BerlinVegan-Qt_5_9_2_iOS_V_Play-Release/

 

Did I miss something in the docs? Did I forget something?

Hi Julian,

can you try whether the Felgo Examples work, for example the Component Showcase?

If the issue also happens for the example or even with a fresh Felgo Project created in Qt Creator,
please remove Felgo with the MaintenanceTool and re-install with our latest installers.

Does the issue only happen for your project or in general?

Best,
Günther

Günther: I will do that. Thanks.

Günther: Thanks for responding. It seems to be our app.

[GüntherFelgo Team]

 

Hi,

if only your project is affected, the issue is maybe related to changes in the Navigation type that were part of the update, please see this topic:
https://felgo.com/developers/forums/t/error-after-the-update-to-2-4

Does your app e.g. use a customized Navigation per platform and are you able to resolve the issues with e.g. the snippet in the above post?

Best,
Günther

[Micu]

Hey Günther et al.,

The thing is: We do have our own menu abstraction (http://www.micuintus.de/2017/10/01/cross-platform-mobile-app-development-for-ios-sailfishos-and-android-with-qtqml/), which I tried to fix. Currently, we create our pages

onLoaded()

of of the NavigationItem: https://github.com/micuintus/harbour-Berlin-Vegan/blob/development/qml/components-v-play/MenuItem.qml#L21

But we don`t receive that signal any longer with the new Felgo version. I did find a solution for the pages to show up again, but also do we no longer receive

the

selected()

signal. Did you change anything there?

[GüntherFelgo Team]

Hi Micu,
thanks for your message.

We’ve found a bug with forwarding these signals in the new Navigation setup. We’ll work to fix this as soon as possible. There will probably be a minor update next week as well, we’d like to include the fix there if possible!

Best,
Günther

Hello,

we have the same issue here.

Our navigation system is completely broken.

Any suggestion for a workaround ? Or, better, is it possible to get sooner the fix ?

 

Many thanks for your help.

Best Regards.

F.
