ListGrid image field and imageURLPrefix

[Hirn]

Version v13.1p_2026-06-21/Pro Development Only (2026-06-21)

I noticed what appears to be inconsistent behavior with ListGrid image fields.

I have a common field definition:

const ListImageField = {
type: "image",
title: " ",
padding: 0,
align: "center",
width: 20, imageHeight: 16, imageWidth: 16,
valueIconLeftPadding: 0,
valueIconRightPadding: 0,
canEdit: false,
escapeHTML: false, canSort: false, canFilter: false, canHide: false, canHover: true, showHover: true };

Case 1

{ ...ListImageField,
name: CONSTANT.TYPE,
imageURLPrefix: "[SKINIMG]users/",
imageURLSuffix: ".png",
canHover: false, showHover: false
}

In this case, the grid always tries to load PNG files from the users folder, even when the value matches an icon defined in the framework icon map (stockIcons.svg).

Case 2

{ ...ListImageField,
name: CONSTANT.TYPE,
canHover: false, showHover: false,
  formatCellValue(value, record, rowNum, colNum, grid) {
     return isc.Canvas.imgHTML({
         src: `[SKINIMG]users/${value}.png`,
         width: this.imageWidth,
         height: this.imageHeight,
         align: "center",
     });;
}

In this case, the icons are loaded correctly from stockIcons.svg. My question is whether the same behavior is expected in case 1 as in case 2.
