Tree Grid does not work as expected



Including multiple tree grids sourced from the same data inside the same section results in displaying duplicate rows in the expanded grid nodes.

Error Messages

Not Applicable

Steps to Reproduce

Create a section with multiple tree grids with the same source in the same section.

Root Cause

A defect in Pegasystems’ code or rules.

The tree grid layout displays child nodes that are use a unique partial. This partial is determined by the containing section and the parent layout ID. Dynamic layout can contain other layouts, but there is no differentiation between cells of the dynamic layout, hence the partial is same for both tree grid layouts. This results in fetching incorrect markup.


Perform the following local-change:

Place each tree grid inside its own section.
