Power Platform Community Forum Thread Details

I'm using a library component, and everything seems to work differently than your usual Power Apps forms etc.

I used to pass all the parameters individually from app 1 to app 2, and before release day, I noticed it dropped 3 parameters, so the URL wasn't displaying them, and taking user to the wrong path as a result.

My record always has a lookup column elsewhere, so The JSON function cannot serialize tables / objects with a nested property called '_ownerid_value' of type 'Polymorphic'.

Launch(
ActionsAppURL,
{
data: JSON(SelectedAction, JSONFormat.IncludeBinaryData)
}

Is there a reliable way to pass the record and populate it in the parent app? I'm trying to pass less parameters, and still I saw the RecordCount parameter go missing, which is what drives most of the behaviour (0 means new action, 1 means existing action, more than 1 list of actions). The purpose is to either land in list of actions, or single action screen

Hello @inanoffice23,

That won’t really work in a reliable way. Passing the whole record via Launch() breaks as soon as the record contains lookup columns (especially polymorphic ones like _ownerid_value), because JSON() can’t serialize them. On top of that, URL parameters can get truncated, so values can silently go missing.

What does work is passing only the values you actually need, but wrapped in a single parameter. For example, pass a small JSON object made up of simple types only (no lookups / records / tables):

Launch(
    ActionsAppURL,
    {
        ActionId: 25,
        RecordCount: 2
    }
)

Then in the target app, read and parse that parameter and load the record again using LookUp().

In App 2 (OnStart or OnVisible):

example:

Set(
    g_ActionDetails,
    If(
        Param("RecordCount") = 1,
        LookUp(
            Actions, //Please use your list or table name
            ActionId = Value(Param("ActionId")) //ActionId - use your comparison column here
        )
    )
);
