If I now paste data into the grid, taking option 2 to paste each line into a separate item, creating items if necessary, PhDProj is not set for the pasted items. Therefore, if I immediately refresh the grid, the newly posted data does not meet the filter and is not displayed.
I would have thought that because the two grid level options are set, the pasted new items should have PhDProj duly and immediately set and should therefore be preserved across the refresh operation.
Of course, the data is not lost – it is somewhere. But that somewhere is rather inaccessible. Certainly, it can be found using the Omnibox option to search the entire file and to show items in the search grid. But that shows the new items to be displayed in - shown in - no grids. Furthermore, from the search dialogue, you can do nothing with the data that you find. You cannot, for example, set a yes/no field such that the data would appear in a grid.
It seems to me that here we have a bug – all pasted data in a grid with auto-assign set for all items should be added to that grid with the yes/no field set even when the data is pasted from the clipboard. We also have an enhancement request, which is that it should be possible to do more with data from the search dialogue, for example to be able in some way to show it in a grid by means of setting a yes/no field.
I am also fairly certain that the shown in column in the search grid does not always show all the grids for which an item meets the filter criteria.
