Error When Creating Custom Summary
posted

Hello, 

I'm having a few issues using custom summaries with nested groups. See details below and provide assistance if possible, any help is appreciated. You will find a stackblitz reproduction of the issue at the bottom.

Scenario: Show only the sum of child level items that are nested in groups.

Problems:

  • Summary shows on each child level.
    • Example:
      • Level1
        • Child 1
        • Child 2
        • Summary of child values should show here and does
      • Summary of all Level 1 children should not show here but does
  • Custom summary to only show the sum value has been defined but all summary values still show

Notes:

  • The console shows an error of "ERROR TypeError: classRef is not a constructor"
    • Stack Trace:
    • HelloComponent.html:4 ERROR TypeError: classRef is not a constructor

  • I'm sure I'm missing some type of wiring but can't spot it. I've followed the examples found at https://www.infragistics.com/products/ignite-ui-angular/angular/components/grid/summaries.html#summaries-with-group-by
  • The "classRef" error shows up even without the grouping.
  • The structure of my reproduction is partly pulled from my personal solution that this problem shows up in.
