BTW, if you haven't created new fields in a database, everything in the copied/pasted items should transfer. So, it's pretty straight forward, really. Pierre was only referring to the extra fields one might have created. At this time, those won't be created on the fly.
At the moment, F5 (refresh) is VERY important to get used to.
In a grid, all
filters/source bar related changes
on items (removing some fields, adding items with the "add item" window...) won't appear/be updated in the grid if you don't refresh .
(So, in the above mentioned case, if you added items using the add item window to an already opened grid, you have to refresh --> that will "reload" all items meeting the source and filters and show them on the grid. Same applies if you untick some key fields on some items so that they don't meet the source anymore : a refresh is necessary to clear them of the grid.)
Having to refresh has some downsides, but also some advantages. But autorefresh is coming anyways (as an option...) -- isn't it, Pierre?
