NAvigate doen't work in Published version (in PowerApps Studio yes!)

[Anonymous]

Hey

I'm working with a Gallery and navigating to a form using  Navigate(Form1;ScreenTransition.Fade;{variable:Gallery.Selected}) and in the form in Items: variable

In PowerApps Studio all is OK, but when I publish the App it doesn't work

Try to open the form , but in less than  second return to the gallery screen

Please, I need to solve is as soon as possible

Thanks in advance

Is Form1 the name of your screen or your Form?

You need to specify the name of the Screen that you want to navigate to in the formula.

I hope this is helpful for you.

I seem to be experiencing the same problem. I haven't noticed any issues while working in PowerApps Studio, but a user who is helping me test noticed almost all of their navigation buttons stopped working.

The user was testing and navigating yesterday afternoon without any problems, but noticed the issue later that evening, continuing into today. I didn't make any code changes to the navigation buttons between those times however.

While troubleshooting, the user was able to get the navigation to work once out of approximately 5-6 refreshes, but nothing consistent. 

I also got the user to enter PowerApps Studio to try testing again and the navigation consistently worked fine for them there, so I am not sure what the problem is between the Studio and the Published version.

Unfortunately, there are a lot of differences between the player and the studio.  The studio is VERY forgiving of badly written formulas and invalid references to controls.  The player is strict and will fail to operate properly with the above conditions.  I personally wish the reverse was true - strict in design and forgiving in play.  

Check your formulas!!!  That is the key. 

If you are hanging results, this will fail. example on a height property: If(someCondition, 100) - There is no false condition.

If you are referencing controls and not their properties, this will fail. example Label1 instead of Label1.Text

So, lots of little things to consider.  

If you are having specific issues with something, then post that formula and it can then be reviewed.

Hi

Thanks a lot for your comments, but I think finally I've found a solution.

I've seen that the problem is that in the Published Version the 'variable' used in 'variable':Gallery.selected in Navigate is loosed. 

Then Navigate really works good but doesn't know the register to edit in the form.

I've testet with Set and also it doen't work

But with UpdateContext it's OK

My solution:

On Select:

EditForm('yourform');;UpdateContext({'yourvariable':gallery.selected})

And in item in the form: '

'yourvariable'

I hope this will useful for other users

Regards
