Last item.data() of pya.LayoutQuery returns None #261
Description
This ticket refers to this issue mentioned in the forum: https://www.klayout.de/forum/discussion/1218/custom-query-in-a-python-script-bugs
In a query like below, the last item.data() unduly returns None. In particular, if there is only one cell instance matching the query, the result is result = [None], which is disappointing.
query = "select cell.name from instances of .. where cell_name ~ 'CellName1'"
result = [item.data() for item in pya.LayoutQuery(query).each(layout)]

Hi Olivier,
thanks for this issue report. I can reproduce it, but that does not seem to be a systematic issue. With "search and replace" the result is fine. I'll check the Python integration code.
Regards,
Matthias
Fixed #261 (iterator must not be incremented while value is used)

I guess I found the root cause. I'll give it some testing and then merge it.
