Tree grid infinite children issue.

I have issue with tree grid. The tree grid is showing me the infinite children if expand any items.

Here is the code.

<vaadin-grid .items = “${this.documentations}”
<vaadin-grid-column path=“Actions” .renderer = “${this._renderActions}”>

public class DocumentationDTO {

private Documentation documentation;

private Long documentationId;

private List<DocumentationDTO> childrenDocs;

}

There is only one “Testing” item and it has only one child

How does your dataProvider look like?

Actually I am just passing items
