Grids are not consistently acting as drop targets #1121

Open joelpop opened 4 years ago

joelpop commented 4 years ago

I’m getting some unexpected behavior with a view I’ve created having three grids. (I’m using 14.1.23.) I’m trying to drag a row from any grid to any other grid using GridDropMode.ON_GRID, but the other two grids don’t always allow it. I’ve also tried it with GridDropMode.BETWEEN with better, but still inconsistent results. Attached is a code sample that demonstrates it. This code is essentially the “Drag Rows Between Grids” example from https://vaadin.com/components/vaadin-grid/java-examples/drag-and-drop. IntegerQueueView.java.zip

Thanks for the issue @joelpop. I move this ticket to Flow repo.

Grid dnd specific issues belong to the component integration repository grid-flow.

I was able to reproduce this a few times on Firefox (not Chrome) but it's really random. Couldn't pinpoint any specific condition under which the issue occurs.
