Deep Linking to Record

[jrybachek]

Hello, 

I am trying to set up deep linking in my Power Apps following the video How to Migrate from App OnStart by Bulb Digital 

I have created an app StartScreen, LoadingScreen with OnVisible property of:

Set(
    isAppLoaded,
    false
);
If(
    IsBlankOrError(Param("ticketID")),
    Set(
        SelectedItemID,
        Value(Param("ticketID"))
    )
);
Set(varItemSelected, true);
Set(
    isAppLoaded,
    true
);

With a timer on the LoadingScreen and an OnTimerEnd property of:

If(varItemSelected,Navigate(OrderFormScreen), Navigate(Screen1));

And for the OrderFormScreen OnVisible property:

If(Not(IsBlank(SelectedItemID)), UpdateContext({varRecord:LookUp(PCSOrders, TicketNumber = SelectedItemID)}))

I have tried to enable the OnStart of the app and I cannot get that to show. Here is the screen I get when trying to load a specific record:

I appreciate any help you may be able to provide.

I made the changes. Passing the item from Screen1 to OrderFormScreen is working again using the varRecord.

I still get the same error when trying to deep link. 

Could it be an issue with TicketNumber being a text field? TicketNumber is the reference field in the Orders SharePoint List.

Again, thank you for all of your input and assistance. I appreciate it greatly.

Hi @jrybachek ,

No ,this is something else - I am actually using the ID as the parameter I send through, which I do on every one of my deep-linked apps and I have never experienced your error. It actually should simply come up as a blank screen if not record is found. As a test. get rid of the Navigation (automatic) and put it on a button on the first screen. See if it lands on that properly and then navigates.

I created a button on the starting screen, which is LoadingScreen. The button has an OnSelect of below.

Set(gblID, 11111 ); Set(varRecord, Blank());Navigate(OrderFormScreen);

I wanted to set the glbID to an existing record. I also cleared the varRecord because I had tested that and the variable was still stored. I get to the OrderFormScreen but it does not bring in the item.

Also, I tested going to just the loading screen, and the OnTimerEnd did work to route me to Screen1 when not trying to use a deep link.

@jrybachek ,

Try the same thing using the deep link - just put all the code on the Button

If(
   !IsBlankOrError(Param("ticketID")),
   Set(
      gblID,
       LookUp(
          PCSOrders, 
          TicketNumber = Param("ticketID")
       ).ID
    )
);
If(
   gblID > 0,
   Navigate(OrderFormScreen), 
   Navigate(Screen1)
);

and the Form Item

LookUp(
   PCSOrders, 
   ID = gblID
)

I also suggest you get away from using a Variable as the Item of a form - unless you update the Variable  -OnSuccess use

Set(
   varRecord,
   Self.LastSubmit
)

your form will not show the current state of the record. I use the gblID on every form I have and it works perfectly.

That gave me progress! Thank you! Tomorrow I will have to move stuff around to get it to work without pressing a button, but that worked as expected, for the most part.

Thank you so much for your help
