Previously the dialog for inserting a relation behaved differently depending on whether the query has two or more than two tables. If there are only two, then you can select either table as the left table and the right table will automatically flip to select the other table. If there are more than two tables then instead it will remove the second table from the list of options for the left table and remove the first table for the list of options for the right table. As you change the values of a combobox it would add and remove options in the other one so that you can never select the same table in both boxes. This behaviour is quite annoying if you happen to want to choose the second table as the left part of the join. In that case you have to first set the right table to something else so that it will appear in the left combobox and let you select it. After that you can select the table you actually wanted in the right box. Instead of that behaviour, this patch makes it always have all the tables available in each combobox. If you select the same one that is already in the other combobox, it will now just shove the selection along by one place including wrapping around back to zero if the last one is already selected. I think this is easier to work with. It also means we don’t have to have a special case to handle when there are only two tables because the general case will have the same behaviour as before the patch.
