Nested Gallery Loading Problem

Posted on by mwferris

Hello,

I have a Gallery nested inside another Gallery using the Planner connection. The "parent" gallery consists of all of a user's plans, and the "child" gallery contains all tasks in a bucket with a specific name (reporting).

The "child" Gallery Items formula is:

Filter(Planner.ListTasks(ThisItem.id).value, bucketId = bucket_id.text)

This is resulting in errors being generated when the app loads, saying the Planner.ListTasks id is invalid. This makes me think that the "child" gallery is trying to load before the "parent" gallery has loaded?

Is there a way to 1) resolve this issue; or, 2) suppress the error message, as the galleries fill in after a few seconds.

Here is what the nested gallery looks like:

I would suggest to have a dummy collection with the shape of a single task and set it to the child gallery when the ThisItem.id is empty (or is blank). Some fields in the dummy collection could even be set to something like "Loading..."

Thanks, that worked. For anyone else, this was what fixed it:

If(IsEmpty(ThisItem.id), Filter(Temp, title="loading..."),Filter(Planner.ListTasks(ThisItem.id).value, bucketId = bucket_id.Text))
