      Current Result

      zss.wpd:660 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'appendZSH')

    at R.<computed>.s.charAt.o.func (zk.wpd:formatted:8724:53)

      Expected Result

       No error

      Debug Information

       After each row size command, a pruning of the current row cache is performed

      this.activeBlock.pruneFromRange()

      If more than 1 row height reduction happen in the same transaction, this can cause next row size reduction targeted rows to have been removed from cache, but the size command is already queued.

      When the appendZSH function is called, the target row is no longer in the activeBlock.rows cache, and fails due to row not found.

       

      Workaround

      <script><![CDATA[
zk.afterLoad('zss', function() {
	var xMainBlockCtrl = {};
	zk.override(zss.MainBlockCtrl.prototype, xMainBlockCtrl ,{
		appendZSH: function(row, zsh) {
			if(!this.rows[this._getVisibleRowIndex(row - this.range.top)]){
				return;
			}
			var result = xMainBlockCtrl.appendZSH.apply(this, arguments);
			return result;
		}
	});//zk.override
});//zk/afterLoad
]]></script>
