OnInstallAppPerCompany

[bachii1010]

Hi

As in the below code when we run the app using F5 or Ctrl + F5 the trigger OnInstallAppPerCompany is not triggering.

Please Suggest

Thanks & Regards

Just a hunge...

This probably happens because you synchronize (default behaviour), therefore don't install, but upgrade. Add this to your launch.

It will remove the previous version first, then actually perform an "install", which will trigger the code.

Note that your data will be wiped every time you deploy from VSCode! So, only necessary when testing your install-codeunit.

I tested this. I have the opposite behavior :-/.

It is always going to run that trigger, no matter what the schemaUpdateMode setting is. #puzzled

Do notice that debugging does not seem to be an option.. . don't know if that is what you are trying to do...

HI Waldo,

As you suggested i have put recreate in launch.Json but it does not seems to work in that way also the trigger OnInstallAppPerComany is not triggering.

Also is debug not possible for this trigger.

Please suggest?

In order to debug, you need code from the web client that triggers it for the moment. We have a backlog item to add more to how debugging works.
The why OnInstallAppPerCompany is not triggering needs investigating

[waldo1001]

It does trigger on my end though...

@kalberes i tried to do both ways(debugging and not debugging) but it is not triggering.

Can you please suggest?

Hi,
Please specify which versions of the AL extension and server are you using.

[bachii1010]

@kalberes i am using March preview update which is 0.15.18771

I have submitted a request for the owning team. As soon as there is a response it will be logged here.

@bachii1010 I'm afraid I have not been able to reproduce this yet on the March preview you mentioned. Can you provide some sample version of the code you are using in the trigger? Or in the codeunit?

[bachii1010]

@HunterFeltman-MSFT i am using the same code as in this document in the below link i additionally kept a message to check if the trigger is running or not.

Please suggest

I'm not familiar with this particular example code, however, I can tell you that the OnInstallAppPerCompany trigger is going to be run in a UI-less 'background' session and as such will never display messages to users, so unfortunately you would never see things in the client.

If you are sure that the 'IsExampleApplicaitonAreaEnabled' function should be responding back with 'false' then you could check the DB to see if 'EnabledExampleExtension' code has actually executed (though it also seems that there are more 'quit early' checks inside that)

If you want to be really sure, I suggest creating a simple dummy table & page and then populate said table in this code.

for example:

table 50000 TempTable
{
    fields
    {
        field(1;PK; Integer) { }
        field(2;Value; Text[250]) { }
    }
    
    keys
    {
        key(PK; PK) { Clustered = true; }
    }
}

page 50000 TempPage
{
    PageType = Card;
    SourceTable = TempTable;
    
    layout
    {
        area(content)
        {
            group(GroupName)
            {
                field(Value;Value) { ApplicationArea = All; }
            }
        }
    }
}

codeunit 50000 TempCodeunit
{
    Subtype = Install;

    trigger OnInstallAppPerDatabase()
    var
        tempTable : Record TempTable;
    begin
        tempTable.PK := 1;
        tempTable.Value := 'Hello, World!';
        tempTable.Insert();
    end;
}

Note: Use the 'recreate' schemaUpdateMode to assert that data is cleared from this table before you F5 multiple times with this code.

You might have to adjust object ids, but with this you could then navigate directly to your page and see if data was inserted into the table (indicating that the trigger did, in fact, run)
To directly navigate to the page, use a ?page=50000 query string parameter to the webclient URL in your browser

@HunterFeltman-MSFT thanks for the update yes i tried with your example it is executing i will go into further details what is going wrong with ours.

Thanks once agian!!!!!

No problem, thanks for letting us know about the potential issue. Hope you figure out the problem in the ApplicationArea example.
