I am working on the creation of a component to help manage my application. The component is initialized with a table of items:

Table(
 // Amenities
 { // Nav Control Properties
 ItemKey: "amenity", ItemDisplayName: "Amenities", ItemIconName: "GiftBox",
 // Custom app management properties
 SortColumn: "AmenityName",
 SortDirection: SortOrder.Ascending
 },
 // Inventory Items (Header)
 {
 // Nav Control Properties
 ItemKey: "inspection", ItemDisplayName: "Inspection Items", ItemExpanded: true,
 // Custom app management properties
 ItemHeader: false
 },
 // Categories
 {
 // Nav Control Properties
 ItemKey: "category", ItemDisplayName: "Categories", ItemParentKey: "inspection", ItemIconName: "WebAppBuilderModule",
 // Custom app management properties
 SortColumn: "Title",
 SortDirection: SortOrder.Ascending
 },
 // Category Items
 {
 // Nav Control Properties
 ItemKey: "catItem", ItemDisplayName: "Category Items", ItemParentKey: "inspection", ItemIconName: "WebAppBuilderFragment",
 // Custom app management properties
 SortColumn: "AmenityName",
 SortDirection: SortOrder.Ascending
 },
...
) // Table

The above "Items" property for the component forces a Reset when changed. The reset copies the table into a collection.

ClearCollect(
 ccolItems,
 Self.Items
);

The properties under Nav control properties are read-only. The properties under Custom app management properties can be updated as needed.

To perform the update I added a Custom Property defined as follows:

The GridSortColumn has the following code in it:

With(
 {
 curItem: LookUp(
 ccolItems,
 ItemKey = Key
 )
 },
 If(
 Not( IsBlank( curItem ) ),
 If(
 // Error: on '<>' in next line
 curItem.GridSortColumn <> SortColumn,
 UpdateIf(
 ccolItems,
 ItemKey = Key,
 {
 GridSortColumn: SortColumn
 }
 )
 );
 SortColumn, // Return passed in Sort Column
 "" // Return nothing if key not found
 )
)

I am getting an error in the above code. I put a comment above the line where I am getting the error.

I do not understand what '_Min' is in the above error.

I tried to setup GridSortColumn_SortColumn (passed property) with a default value, since it is optional. That code is:

LookUp( ccolItems, ItemKey = cgblItemKey, GridSortColumn )

I get an error here to that is just as helpful:

I have no idea what that means.

This was working at one point. It broke when I changed the Key parameter from Optional to Required. Even if I switch it back it still gives me the error.

Any thoughts or ideas would be helpful.

Thank you.
