Wt

Hi,

I use a WStandardItemModel with a WSortFilterProxyModel to filter rows using the filterKeyColumn() of class WSortFilterProxyModel. I have enabled dynamic sorting using setDynamicSortFilter(true)!

If I change an filterKeyColumn item and some rows are filtered I get the following core dump. I figured out a workaround by the following steps:

• setDynamicSortFilter(false);
• change filter key column items
• setDynamicSortFilter(true);

However the core dump should be fixed!
