AUR6004

Error Message

AUR6004: Invalid render target. The target element must have a parent node.

Description

This error occurs when the virtual repeater attempts to insert/move views, but the render target is detached (its parentNode is null). Virtualization requires the target to be in the DOM.

Example Trigger

<!-- ❌ The virtual-repeat host is conditionally removed while still active -->
<div if.bind="show">
  <div virtual-repeat.for="item of items">${item}</div>
</div>

If show flips rapidly during activation, the repeater may try to render into a detached node.

Correct Usage

• Avoid tearing down the virtual-repeat host while it is initializing.

• Prefer guarding the entire component (or delaying data/activation) so the repeater initializes on a stable DOM tree.

Troubleshooting

• Check lifecycle timing: ensure the host stays attached during bind/attach.

• If you toggle if.bind, consider debouncing the toggle or moving virtualization to a stable container.
