Uncaught TypeError: $0 is null

[SpilkoRobert]

Hi,

I experience some error logs in browser console, when adding a vaadin Combobox to a cell...
Minimal repro:
Table table = new Table();
TableRow tableRow = new TableRow();
TableDataCell tableDataCell = tableRow.addDataCell();
tableDataCell.add(new ComboBox<>());
table.getBody().addRows(tableRow);
renderedComponent.add(table);

Uncaught TypeError: $0 is null

Can you please check and try to reproduce it?

Thank you,

Hi, I tried to reproduce this issue but could not. Can you please elaborate your use case a bit more? Especially which Vaadin version you are using and in which context the table is used (what is that renderedComponent for instance) ?

Hi,

Vaading version is: 24.3.6
HtmlTable version is: 1.2.0
renderedComponent is a VerticalLayout

What might be important is that the parent of this part of the UI is rendered conditionally based on reflection.

For this we also...:
@LoadDependenciesOnStartup(Bundle.class)

@route(value = "bundle")
@uses(Table.class)
public class Bundle

[stefanuebe]

2.3.6 or 2.6.3?

What happens, if you leave the table out and only add the ComboBox to your layout in the same constellation?

And have you tried adding the @uses(Table.class) to your AppShell for once?
