LookupField in headerRow of the grid bug and workaround

[XandrMaster]

Thank you for very cool component 👍 ! But there is small bug if you use this component in the HeaderRow of the standard Vaadin Grid.
There is a Kotlin example :
val headerRow = Grid.appendHeaderRow() headerRow.getCell(column).component = LookupField().apply { comboBox.isClearButtonVisible = true grid = UsersGrid() }

• this code works not well : If you click to open the search dialog button you will see just empty Grid with no any columns or settings. It bug reproduced only in headerRow of grid .
• Workaround : just setup Grid in the constructor : LookupField<Users>(UsersGrid(), ComboBox()) instead of LookupField.setGrid(Grid<T> grid)
