Kinetic Grid Grouping Fix

See it in 10 seconds

A live capture on a 4,466-row Epicor Kinetic Job Entry grid — grouping then ungrouping balloons it to ~2 GB without the fix, and stays windowed at ~80 rows with it.

What it fixes

In Epicor Kinetic, grouping a large data grid by several columns and then ungrouping it defeats the grid’s virtual scrolling: every row re-renders into a single table body. On a ~4,400-row grid that balloons the tab to roughly 2 GB of heap and ~470,000 DOM nodes, making the browser sluggish or crashing the tab.

This extension applies a small, targeted patch to Kinetic’s own grid code so that ungrouping restores the normal virtual-scroll window. With the fix on, the same group→ungroup cycle stays at about 80 rendered rows and a few hundred MB of heap.

Install & use

Install the extension

From the Chrome Web Store listing pending review, or load it unpacked from the source folder via chrome://extensions → Developer Mode → Load unpacked.

Flip the toggle ON

Click the toolbar icon and turn on the switch. It is OFF by default — nothing changes until you enable it.

Reload your Kinetic tab

The patch is applied as main.js loads on the next refresh. Group and ungroup freely — the grid keeps its compact window.

Expected: in the default mode Chrome shows an “extension is debugging this browser” banner while the fix is ON. That is normal — it is how the patch is delivered — and it disappears the moment you turn the fix OFF.
