ERROR TypeError: this.cloneObject[this.mainElement.id] is undefined in DashboardLayouts component

[caslavhaslerrail]

There is an error inside DashboardLayouts component that occurs after adding new panel but only if previous panel was dragged or resized

This happens because startRow property is not destroyed in removeAll() mehod here:

And because startRow property is not destroyed in removeAll() method, when updating layout in updatePanelLayout() method it is checking for swap and then it fails because before updating panel layout all panels are removed but startRow property is not destroyed.

I am using Angular 11 and SyncFusion DashboardLayout 19.4.52.

Can you please fix this because this component is mission critical for our project and fix seams like very trivial?

Hi @caslavhaslerrail

We have prepared a Dashboard Layout sample in Angular 11 and ensured it with the shared details. However, adding panels works fine after drag and resize without any console errors in both 19.4 and latest version(25.2).

Attached sample for reference.

If possible, please give a try on upgrading to our latest version of layouts package.

Sample with latest version: Syncfusion-Dashboard (forked) - StackBlitz
