Quick View 'locating' error when block matrix is reduced while QV is temporarily inactive

[chrherold]

The following problem occurs when switching Quick View on and off by the button in the header
in the following scenario:

• In the block matrix, there is at least 2 filtersets OR 2 datasets
• QuickView is activated and an entry is selected to be displayed
• QV is deactivated by the "Quick View" button
• one of the alt least 2 filtersets OR datasets is removed
• QV is reactivated by the "Quick View" button

The following error is displayed:

    slot_id, filt_id = self.get_quickview_ids()
TypeError: 'NoneType' object is not iterable

now if shift + click is used, in the first attempt the following error is displayed:

I guess its an issue with the matrix the QV expects to find. it is not an issue if the matrix is extended. It remains an issue if a (e.g.) filterset is removed and one is added.

One way to catch this would either to try and still find the correct location it last was or to just display the initial message to select a field by shift+click again which would anyway be necessary in case the QV selection was removed.

(PS. Deef started to play with the program, hunting for exceptions :)
