Grid.select(item) does not highlight the newly selected row.

[masbaehr]

If i select a row programmatically the row is not marked as selected

The select method i used is this:

Grid.select(item)

A row selection with the mouse marks the selected row in light-blue, but the programmatic (pre)selection does not highlight the selected row

Tested with the following example and could not reproduce:

Grid<String> grid = new Grid<>();
grid.addColumn(string -> string);
grid.setSelectionMode(SelectionMode.SINGLE);
grid.setItems("foo", "bar");
grid.select("foo");
add(grid);

Result:

See also the examples of programmatic selection: https://vaadin.com/components/vaadin-grid/java-examples/selection

Closing as invalid.

I'm also seeing this issue. I tried your example and it worked fine. However once I point the grid to an actual object (and not just the list of strings), that's where it breaks for me.

here's my code:

here's a screenshot of the log output:

here's a screenshot of what I see in the browser:

as you can see in the screenshots, other than me calling on my specific class to populate the grid, it's identical to yours. Also, based on the log output, it is "selecting" the first item fetched by default. However in the browser, no row is highlighted. I've greatly simplified this from what I'm trying to do for real. I'm actually working with a multi-select for real, but this appears to be the same issue regardless so I'm just using a single select here.

thanks for your help.

@mikethomas77055 did you solved it? It seems like items have different hashCode/equals results.
But I don't see the selection for the item being one of items of grid which equals by reference.
So I don't know what's wrong here.

I ended up solving it by adding this to my AbstractEntity class (all of my entity classes extend AbstractEntity, so adding it to AbstractEntity solved this for all entities).

@mikethomas77055 thanks for reply!
I found the reason of my issue - the Grid component works well, the reason was PaginatedGrid (I use it) which resets selection in it's onAttach event.
